PPM-WCY61 2 Wire 20mA Differential Pressure Transducers

PPM-WCY61-P050A Infectious Disease Room 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
