SP38D Piezoresistive silicon differential pressure transmitter is widely used in process control, environmental control, flow control, hydraulic and pneumatic equipment, servo valve and transmission, chemical products and chemical industry as well as medical instrument and so on.
The core sensor is high precision piezoresistive silicon technology with SP38D, it can be built-in static pressure and temperature compensation, which maximum improves the static pressure and temperature performance of the sensor. With high overload and high static pressure, high static pressure up to 40MPa. SP38D is suitable for all kinds of harsh environment, the working temperature is -40~120°C.
