4-20mA industrial pressure transmitter for hydraulic system


Hi sendo senosr, we are a research company, we are looking for industrial pressure transmitters that offer 4-20mA output signal with 25Mpa gauge pressure, the pressure connection 1/4" npt is acceptable to us. The sensors will be used in oil pressure in a hydraulic system, and also for measurement of carbon dioxide pressure. The sensors will measure relatively fast changing pressure, so we prefer to have at least 100 reading per second for each sensor. Both media and environment temperature will not excedd 40C. In the future the sensors will be used in the similar applications.

SS302 Series 4-20mA industrial pressure transmitter

l CE conformity

l 4-20mA, 1/4"NPT, 250bar(g)

l Stable Piezoresistive sensors

l Compact, rugged construction

l Stainless steel 316 diaphragm

l Working temperature: -20 to 80°C


SS302 series piezoresistive pressure transmitters are the basic type in sendo sensor, also it is the most widely used one.

SS302 series adopt a high performance piezoresistive pressure transducer as the sensing part, used with a special digital circuit, widely temperature compensated, well suitable for precision applications in industrial environments for pressures ranging from 0,1 to 1000 bar, liquids or gas.

A modular concept uses the selection of off-the-shelf capsules, allowing a customised production. Numerous options and variants are available, fully adapted to the customer requirements: Mechanical(pressure connection) and electrical interface, ports,signal outputs, materials in media contact, oil filling, special features…
