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

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

The 230 model of the Performance Series pressure switches utilises bourdon tube type sensors that offer a very linear response to pressure change. This sensor, coupled with a precision stainless steel mechanism designed to minimise friction in the moving parts, helps deliver the market leading performance customers have come to expect from the series. The model 230 Pressure Switch is suitable for setpoints between 0bar and 600bar with maximum working pressures up to 690bar. (EAC certification is available on request).
This range of products was initially created over 50 years ago. Continual product improvements and design updates ensures that this range of products provides a consistent level of measurement and control, giving customers, in industries which may be susceptible to corrosive atmospheres, confidence that the measurement is accurate.
Key Features

The 306 Performance Series differential pressure switches utilise a nitrile diaphragm based sensor. This, when coupled with a precision stainless steel mechanism designed to minimise friction in the moving parts, helps deliver the market leading performance customers have come to expect. The model 306 Differential Pressure Switch is suitable for setpoints between -12.5mbar and 4bar with maximum working pressures up to 15bar. Also available in the 386 model (EAC certification is available on request).
