Pressure gauge with diaphragm seal
Model: P761 (Pressure gauge with inline type diaphragm seal)
P762 (Pressure gauge with extension type diaphragm seal)
P763 (Pressure gauge with pad type diaphragm seal)
Spec. sheet no. PD07-08
Service intended
Pressure gauge with diaphragm seal 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.
Model : P761
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
Model : P762
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
Model : P763
