PPM-WCY61-P050A Low Differential Pressure Transducer
Product Introduction:
It is consisted of stainless steel diaphragm and gilt ceramic fixed
electrode. When pressure changes, the space between two electrode
pad also changes, which result in the change in capacitance value.
And then the unique detective circuit will transfer the change of
capacitance value into linear DC signal.
inherit the consistent characteristics of high-precision,
rapid-response and low range. Considering the requirement of
pharmaceutical plant and clean room for low differential pressure
transducer, on-site LCD is developed and accessories with non-dust
accumulation surface are added to meet the industrial applying
requirement; so it is a desire choice for pharmaceutical plant,
clean rooms of electronic factory and no-dust laboratory. low
differential pressure transducer can measures pressure difference
or gauge pressure (static pressure) and can choose the output
signal in 4-20mA, 0-5VDC or 0-10VDC. transducer has conducted
temperature compensation with an exciting voltage of 24VDC and can
choose 24VAC as power supply for voltage signal product. The
minimum measurement of Model 261C range is at 0 ~ 25Pa with an
accuracy of ±1%FS at room temperature; The unit are temperature
compensated to ±0.06%FS/°C thermal error over the temperature range
+5 to +65°C.
Applications :
Pharmaceutical Plant
Clean Room
Bio-Safety Labs
Infectious Disease Room
Stairwell Fire and Smoke Protection
