Pressure Sensor

Diffused silicon pressure sensor is often used in industries with high demands on automation, including heat supply, refrigeration, chemical engineering, coal mining, petroleum, food processing, water supply, etc. Because of its intrinsic characteristics, this collection of pressure transmitter cannot be used for high or low temperature mediums.
