Type: P791, P792

 

Service intended

 

P790 series diaphragm seal are suitable for conditions where the process medium can cause corrosion to the instrument connection and the pressure sensing element, which the process medium contains suspended solid particles are viscous and be clossed. It is also suitable for where the process medium can freeze or solidify the internal parts of the instrument and where the medium requires flushing from the system to prevent contamination.

 

Design

 

Instrument welded diaphragm with threaded process connection, require hydraulic fluid to transmitter pressure to instrument.

 

Filling liquid

 

Silicone oil

 

Working temperature

 

Ambient : -20 ~ 65 °C
Fluid : Refer to filling liquid reference table

 

Diaphragm material

 

Diaphragms are available in many corrosion resistant materials. Compatibility of selected material and process fluid should be determined by the user

 

Temperature effect

 

Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately
±0.5 % per 10 ℃ of full scale
