SHDP/GP Differential Pressure/Pressure Transmitter with Remote Diaphragm seals provides a kind of reliable measuring way to avoid the measured medium from directly contacting with seal diaphragm of the transmitter.

Transmitters with Remote Diaphragm seals are suitable for the following operation conditions:


  • Mediums with high temperature should be isolated with transmitter.
  • Measured mediums have corrosion to transmitters.
  • Suspending liquid or mediums with high viscosity
  • Measured mediums solidize or crystalize due to change of environment or technological process temperature.
  • Strict purification of measuring head is needed for replacing measured mediums
  • Measuring head must be kept clean and sanitary.
  • Pressure measurement of sealed container.

Effect Factors

1. Temperature Effect

Remote diaphragm is normally equipped with 1.5 m capillary;


  • PFW Pancake seal and SCW Sanitary tri-clamp seal


The error from temperature effect on PFW Pancake seal and SCW Sanitary tri-clamp seal is less than 0.62Kpa/55℃.The error increases 0.2Kpa when the capillary increases per 1.5 meters.


  • RTW Threaded remote seal and RFW flange remote seal


The error from temperature effect on RTW Threaded remote seal and RFW flange remote seal is less than 1.99Kpa/55℃.The error increases 0.62Kpa when the capillary increases per 1.5 meters.

2.  Power supply Effect

Less than 0.005 % of output range

3. Load Effect

No load effect when the power supply is high than 12V DC.

4.  Installation Position Effect

Max 250Pa effect but can be adjusted, no effect on the measuring range.
