◆ Diaphragm seal type pressure gauge ◆
● Model : P710-P720-P730 : P711-P712-P721-P722-P731-P732
● Service intended :
Suitable for the situation Where the process medium would corrode the instrument connection and pressure sensing element. Where the process medium contains suspended solids,or is sufficiently viscous to clog the instrument connection and pressure sensing element. Where the process medium might freeze or solidify in the instrument connection and pressure sensing element due to ambient or process temperature change. Where the process medium requires flushing from the system to prevent contamination.
● Design : Internal diaphragm
● Accuracy : Refer to gauge model
● Suitable Pressure range (MPa, kPa, bar) :
·-0.1 ~ 0 to -0.1 ~2.5kPa
·0 ~ 0.1 to 0 ~ 35MPa
● Filling liquid : Silicon oil KF96(-20~200°C)
● Working temperature :
Temperature rating of the diaphragm seals depend on the fill fluid the diaphragm material and the lower housing material. standard fill fluids are available for temperature ranges from -20°C to 200°C
● Diaphragm material :
Diaphragms are available in many corrosion resistant materials. Compatibility of selected material and process fluid is the responsibility of user.
● Upper flange (gauge side) : Stainless steel (304SS, 316SS)
● Diaphragm :
- Stainless steel(316LSS)
- Monel, Hastelloy-C
- Tianium, Tantalum, Nickel, Alloy20
● Under flange(Process side) :
- Stainless steel (304SS, 304LSS, 316SS, 316LSS)
- Monel, Hastelloy-C, Titanium, Nickel
● Process connection :

- Model P720- P730 : Flanges to ANSI- JIS or other Standard
● Optional extras :
- Diaphragm and lower flange are available in PTFE coating or PTFE lining (see note)
- Lower body (process side) are available in purging plug or heater jacket.
● Note : PTFE lining is available up to 10MPa (coating) for P720 and P730 series.
