SP38D Piezoresistive silicon differential pressure sensor

The core sensor is high precision silicon technology with SP38, it can be built-in static pressure and temperaturecompensation,
which maximum improves the static pressure and temperature performance of the sensor.With high overload and high static pressure,
high pressure up to 40MPa. SP38D is suitable for all kinds of harsh environment, the working temperature is -40-120℃.

SP38D Piezoresistive silicon differential pressure transmitter is widely used in process control,environmentalcontrol,flow control,
hydraulic and pneumatic equipment,servo valve and transmission,chemical products and chemical industry as well as medical isntrument and so on.
