Complete range of diaphragm seals for application on all our pressure and differential pressure instruments.

As part of the Delta Mobrey Performance Series, model version 207 has been manufactured specifically for applications which need to understand levels of absolute pressure, the 207 pressure switch incorporates a sealed reference vacuum for true absolute pressure sensing.
This concept for this robust range of products was developed over 50 years ago. Each model has gone through a range of modifications and enhancements since then, ensuring these products give a consistent level accurate measurement in industries where chemical attack is possible. The Performance range is robust and a hardworking fundamental set of instrumentation.
The 207 Pressure Switch is suitable for setpoints between 0 and 1 bar absolute with maximum working pressures up to 3 bar. (EAC certification is available on request).
Key Benefits

The GR7 Temperature Switch provides users with a compact, robust and hermetically sealed switch for use in safe and hazardous areas. This makes them particularly suitable for panel mounting in harsh environments. This product comes with a rigid or semi-rigid thermal system and is suitable for setpoints between -40°C and +350°C, with a maximum working temperature of up to 360°C (EAC certification is available on request).
Key Features

The model D35 Differential Pressure Transmitter comes fitted with two diaphragm seals. It is suitable for measuring pressures from -100mbar to 70bar with maximum working pressures up to 420bar. The D Series SMART Differential Pressure Transmitter is suitable for a wide range of applications for measuring differential pressure, level and flow.
Key Features

Delta Mobrey’s 2HT Pressure Transmitter offers customers a compact HART transmitter housed in a robust, all stainless steel enclosure.
The 2HT can be supplied with an optional D-CAL digital display that not only provides users with a visible indication of the measured pressure but that also provides users with access to over 80% of the transmitters HART commands, therefore reducing the need for costly third party communicators. For applications where the ambient temperature can vary significantly, the 2HT can be supplied with an optional high accuracy calibration enabling the accuracy to be maintained within 0.1% for ambient temperatures ranging from -30°C to +70°C.
The model 2HT pressure transmitter is suitable for measuring pressures up to 1000bar with maximum working pressures up to 1500bar and has been designed to work in harsh and heavy duty applications, such as off-shore.
