Product Description

Waterproof 20mA SS316L Digital Pressure Transducer 0

FeaturesWaterproof 20mA SS316L Digital Pressure Transducer 1

  • Aluminum-alloy electronic housing; protection IP65;
  • Reversed signal polarity; moment overcurrent,overvoltage, interference protection;
  • Optional signal output;
  • Gauge, absolute and sealed gauge optional
  • Offset and full scale adjustable
  • LCD indicator optional
  • Stainless steel material contacting with the media; flush diaphragm and tantalum diaphragm optional;


The product uses piezoresistive OEM pressure sensor as sensing element, which is accurate tested and laser trimmed to compensated zero and sensitivity in wider temperature range. The amplifier circuit transforms sensor signal into standard output signal. Through long-term aging and stability testing, the whole product’s performance is stable and reliable. The product is suitable for rugged environment which needs zero elevation and range adjustment, could be widely used for process control and pressure measure of petroleum, chemi-industry, metallurgy, power station, textile industry, building material, hydrology and environment control, etc.
