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
