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.
Instrument welded diaphragm with threaded process connection, require hydraulic fluid to transmitter pressure to instrument.
Ambient : -20 ~ 65 °C
Fluid : Refer to filling liquid reference table
Diaphragms are available in many corrosion resistant materials. Compatibility of selected material and process fluid should be determined by the user
Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately
±0.5 % per 10 ℃ of full scale
