HPT708 Monocrystal Silicon Differential Pressure Transmitter
HPT708 DP transmitter for Oxygen clean sensors & instruments which have sensor cells that are dry or filled with a halocarbon oil fill, which will not burn when exposed to an ignition source in an Oxygen environment.
Application :
● Liquid oxygen/ nitrogen/CO2 level application
● Automatic testing system
● Storage and fuel, Oil, Water Tank applications
● Gas DP pressure measurement
● Chemistry Industry level application
● Petrochemical industry
Advantages
01Filling fluid Halocarbon oil /100% O2 compatible
02All media wetted parts are cleaned oil grease free
03Improved EMC resistance and reduced installation sensitivity
04Linearized and temperature -compensated output signal
05Calibration of zero /Span and Turn -down
06It can be used in areas where there is a risk that the device will be exposed to high levels of pure Oxygen
