Diaphragm pressure gauge with seal type

Model : P761,P762,P763

Service intended

Diaphragm seal type gauges are suitable for the situation where the process medium would corrode the instrument connection and pressure sensing element. Furthermore, this type of gauge is suitable for corrosive, highly viscous, crystallising or hot pressure media. Additionally, it is recommended to be used where the process medium might freeze or solidify the instrument connection and pressure sending element due to the ambient or process temperature change and where the process medium requires the flusing from the system to prevent any contamination.

Design

Internal diaphragm

Accuracy

Refer to gauge model

Suitable pressure range (MPa, kPa, bar)

-0.1 ~ 0 to -0.1 ~ 2.5 MPa
0 ~ 0.1 to 0 ~ 35 MPa

Filling liquid

Silicone oil

Working temperature

Temperature rating of the diaphragm seals depends on the fill fluid, the diaphragm material and the lower housing material. Standard fill fluids are available for temperature range -20 ~ 200˚C

Diaphragm material

Diaphragms are available in many corrosion resistant materials. Compatibility of selected material and process fluid is the responsibility of user

Temperature effect

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