ABB 266HSH Overview

The ABB 266HSH is a high overload gauge pressure transmitter developed for process measurement applications where the pressure instrument may be exposed to demanding operating conditions.

ABB describes the 266HSH as a high overload gauge pressure transmitter capable of measuring liquid, gas or steam pressure in a pipe or on an open tank. The transmitter is designed to maintain measurement performance in demanding ambient and process conditions. :contentReference[oaicite:2]{index=2}

The 266HSH combines pressure sensing technology with electronic signal processing and configurable communication capabilities. This allows it to operate as part of a larger process instrumentation and automation system.

High Overload Pressure Measurement

High overload capability is one of the defining characteristics of the ABB 266HSH.

Industrial pressure transmitters can encounter pressure conditions significantly above the normal measuring range during process disturbances, startup conditions or abnormal operating events. The 266HSH is designed specifically for applications requiring high overload resistance.

ABB specifies maximum working pressure up to 105 MPa, equivalent to approximately 15,225 psi. :contentReference[oaicite:3]{index=3}

Gauge Pressure Measurement

The 266HSH is a gauge pressure transmitter. Gauge pressure measures the pressure of the process relative to atmospheric pressure.

This measurement principle makes the transmitter suitable for monitoring pressure in process pipelines, vessels and other industrial equipment where pressure is evaluated relative to the surrounding atmosphere.

The 266HSH is therefore different from the ABB 266NSH, which is designed as an absolute pressure transmitter.

Liquid, Gas and Steam Applications

The ABB 266HSH can be used for measuring pressure in different process media.

ABB specifically identifies liquid, gas and steam as suitable measurement media for the 266HSH. :contentReference[oaicite:4]{index=4}

This broad process compatibility makes the transmitter applicable to many industrial systems, including utility processes, production equipment, fluid handling systems and pressure-controlled process lines.

Industrial Process Instrumentation

Pressure measurement is a fundamental part of industrial automation. Pressure values can be used for process control, equipment monitoring, alarm generation and operating-condition analysis.

The ABB 266HSH can provide pressure information to a process control or monitoring system through its configured electrical and communication interface.

Depending on the selected transmitter configuration, the instrument can be integrated into conventional analog systems or digital fieldbus architectures.

Communication Options

The ABB 266HSH platform supports multiple communication technologies. ABB lists 4–20 mA HART, low-power 1–5 V HART, WirelessHART, PROFIBUS PA, FOUNDATION Fieldbus and Modbus among the available communication options. :contentReference[oaicite:5]{index=5}

The exact communication method is determined by the ordering configuration of the individual transmitter. Therefore, the complete model code should be retained when identifying a specific unit.

HART Communication

HART communication provides digital communication in conjunction with conventional process signal transmission.

For compatible 266HSH configurations, HART can be used for transmitter setup, monitoring and access to instrument information while maintaining compatibility with appropriate analog process instrumentation.

ABB also provides configuration tools and device descriptions for its 266 pressure transmitter family. :contentReference[oaicite:6]{index=6}

WirelessHART Option

The ABB 266HSH platform can also support WirelessHART.

WirelessHART can reduce the need for dedicated signal wiring in suitable process installations and allows pressure measurement information to be incorporated into wireless industrial monitoring architectures.

ABB states that WirelessHART functionality can help reduce installation complexity by eliminating complex wired infrastructures in appropriate applications. :contentReference[oaicite:7]{index=7}

Modbus Communication

ABB also offers a Modbus version of the 266HSH pressure and temperature transmitter.

The Modbus implementation provides access to pressure information and optional process temperature information through compatible host systems. ABB describes the Modbus 266HSH as an intelligent pressure and temperature transmitter capable of communicating with host devices supporting the Modbus protocol. :contentReference[oaicite:8]{index=8}

Pressure and Temperature Information

The 266HSH platform can provide pressure measurement and, for applicable configurations, process temperature information through an externally connected Pt100 resistance temperature detector.

This capability can allow pressure and temperature information to be handled within a common instrumentation architecture.

Accuracy

ABB specifies a base accuracy for the 266HSH starting from approximately ±0.06%, depending on the selected configuration and operating conditions. :contentReference[oaicite:9]{index=9}

The actual measurement performance of an individual transmitter depends on the sensor range, configuration, process conditions, temperature effects and calibration requirements.

Sensor Range

The 266HSH is available with different sensor ranges. ABB’s product information identifies span limits extending from approximately 16 kPa to 105,000 kPa, with the exact range depending on the selected sensor configuration. :contentReference[oaicite:10]{index=10}

When selecting or replacing a transmitter, the calibrated range and sensor code should therefore be checked against the original process requirement.

Configuration Code

The complete designation 266HSH.P.S.B.A.7-LS.B6 contains multiple configuration positions defining the specific construction of the transmitter.

For this reason, the full ordering code is more useful for product identification than the basic model name 266HSH alone.

ABB documentation uses structured ordering information to define sensor type, wetted materials, process connection, housing configuration, output, display and mounting options. :contentReference[oaicite:11]{index=11}

B6 Mounting Bracket

The B6 configuration identifies a pipe or wall mounting bracket made from carbon steel in the 266HSH ordering structure.

ABB documentation identifies B6 as a mounting bracket for pipe or wall installation and distinguishes it from the B7 stainless-steel bracket option. :contentReference[oaicite:12]{index=12}

The mounting bracket provides a mechanical solution for installing the transmitter on suitable pipe or wall structures.

LS Configuration

The LS element in the product code represents an additional configuration option within the ABB 266HSH ordering structure.

Because ABB uses several configuration positions and option codes within the 266HSH ordering system, the complete designation should be retained when documenting the instrument.

The exact meaning of individual option combinations should be confirmed against the applicable ABB configuration documentation for the relevant product revision.

Barrel Housing Design

The ABB 266HSH family is available in different housing and electrical connection configurations. Documentation for the P-style transmitter identifies barrel housing versions and associated mounting arrangements.

The housing configuration determines how the transmitter electronics and electrical connections are physically arranged within the installation.

Process Connection

The process connection is one of the most important parameters when selecting a pressure transmitter for an existing installation.

ABB offers multiple process connection configurations across the 266HSH family. Depending on the sensor and ordering code, options include different threaded process connections and material arrangements.

The exact process connection for 266HSH.P.S.B.A.7-LS.B6 should be verified against the corresponding ABB ordering documentation and nameplate before replacement or installation.

Wetted Materials

Pressure transmitter wetted materials are selected according to the process medium and operating environment.

ABB’s 266HSH ordering system includes different diaphragm, process-connection and fill-fluid configurations. The correct material combination is important when the transmitter is used with corrosive or chemically demanding process media.

The exact wetted-material configuration should always be matched using the complete model code.

Through-The-Glass Configuration

Selected ABB 266 transmitters can use ABB’s TTG, or Through-The-Glass, technology.

This technology allows configuration of the transmitter through the glass without removing the front cover. ABB identifies TTG as a feature intended to simplify field configuration and reduce the time required for instrument adjustment. :contentReference[oaicite:13]{index=13}

Local Display and Configuration

Depending on the selected option, the 266HSH can be equipped with an LCD display for local process-value indication and instrument configuration.

ABB documentation identifies configurable display information such as process value and output percentage on the bargraph. :contentReference[oaicite:14]{index=14}

A local display can be useful during commissioning and routine process inspection because the pressure value can be viewed directly at the transmitter.

Configuration Software

The ABB 266 pressure transmitter family can be configured using compatible PC configuration tools and device description software.

ABB documentation states that configurable parameters, including range values, can be changed using configuration software with the appropriate DTM for 266 models. :contentReference[oaicite:15]{index=15}

This provides an additional method of commissioning and maintaining the transmitter beyond local instrument controls.

Safety Applications

ABB identifies SIL2/SIL3 certification according to IEC 61508 as an important feature within the 266 pressure transmitter portfolio. :contentReference[oaicite:16]{index=16}

The applicability of a specific safety certification to an individual transmitter depends on its exact configuration, certification status and intended safety-system architecture. The relevant nameplate and certification documentation should therefore be checked for the specific unit.

The ABB 266HSH can be applied to a wide range of industrial pressure measurement tasks.

• Process pipeline pressure measurement
• Liquid pressure monitoring
• Gas pressure measurement
• Steam pressure measurement
• Industrial utility systems

The 266HSH can serve as the field measurement device between a process and a control or monitoring system.

The transmitter senses process pressure, converts the measurement into the configured output signal and can communicate additional information through supported digital communication protocols.

This architecture allows the pressure measurement to be incorporated into PLC, DCS, SCADA and other industrial process-control environments when the relevant communication interface is supported.

High-Pressure Process Measurement

The high overload design makes the ABB 266HSH particularly relevant to applications where pressure conditions can be severe.

The specified maximum working pressure of up to 105 MPa demonstrates the high-pressure capability available within the 266HSH product family. The actual allowable pressure for an individual configuration must be determined from its sensor range, process connection, temperature and applicable technical documentation. :contentReference[oaicite:17]{index=17}

Long-Term Process Stability

ABB describes the 266HSH as providing long-term stability under extreme ambient and process conditions. :contentReference[oaicite:18]{index=18}
