¡ß Diaphragm seal type low pressure gauge ¡ß
¡Ü Model : P428 - P429
¡Ü Service intended :
The P428 and P429 series are designed to measure low, vacuum or compound pressure. These series are consisted of diaphragm which is to protect device and designed to isolate pressure gauge from corrosive, contaminative, hot viscous pressure media.
¡Ü Design : Internal diaphragm
¡Ü Nominal diameter : 100, 150mm
¡Ü Accuracy : ¡¾1.5% of full scale
¡Ü Scale range (kPa, mbar) :
- -1 ~ 0 to -30 ~ 0kPa
- ¡¾0.5 to ¡¾15kPa
- 0 ~ 1 to 0 ~ 35kPa
¡Ü Working pressure :
- Steady : 75% of full scale
- Over range protection : 130% of full scale
¡Ü Working temperature :
- Ambient : -20 ~ 65 ¡ÆC
- Fluid : -20 ~ 80¡ÆC
¡Ü Upper flange (gauge side) : Stainless steel (304SS,316SS)
¡ÜDiaphragm :
- Stainless steel(316LSS)
- Monel, Hastelloy-C
¡Ü Upper flange (process side) :
- Stainless steel (304SS, 304LSS, 316SS, 316LSS)
- Monel, Hastelloy-C
¡Ü Process connection :
- Model P428 : PT, NPT, & PF others feasible
- Model P429 : Flanges to ANSI, JIS & other standard
