Product Description

Model 266HRH is a high overload gauge pressure transmitter characterized by the remote seal construction and suitable  for measuring liquid, gas or steam flow as well as level, pressure and density.


This transmitter features in-field replaceable electronics module that thanks to the auto-configuration functionality  dramatically improves plant productivity. Its intuitive plug-and-play display with easy setup procedure really helps  users by saving time and lowering maintenance and inventory costs. Moreover, the innovative TTG (Through The Glass)  technology allow users to configure the instruments in the field without removing the windowed front cover and  consequently to save a lot of time.

SIL2/SIL3 certification issued by TÜV Nord according to IEC 61508 represents another key-feature within 266 pressure  transmitter portfolio. This certification is a real guarantee of protection and makes of 266HRH the smartest fit in  Safety-critical loops.


266HRH features WirelessHART communication protocol allowing a shorter installation times by eliminating complex wired  infrastructures, and lower overall implementation costs of process measurement.

266HRH battery life is about 10 years at 32 sec. update rates, delivering a very cost effective and reliable solution  to monitor your process assets.

Pressure Transmitter FAQ

What is a pressure transmitter used for?

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.

How do I choose the right pressure transmitter?

Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.

What is the difference between gauge, absolute and differential pressure transmitters?

Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.

Can Xinyi Instrument provide customized pressure transmitters?

Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
