Piezoresistive pressure transducer -20 to 20kpa for hydraulic system pressure

Time:2019-03-22

Application:

The sensors will be used to monitor a closed hydraulic system pressure whose fluid may be either oil-based or water-based, but always chemically compatible with standard 316 SS.

Temperature:
The usual system working temperature is between 35 and 45°C, and the environment temperature inside the machine is between 30 and 35°C.
