Stainless steel pressure transmitter
FST800-215-A Hunan Firstrate Sensor Co., Ltd.

The FST800-215 explosion-isolated pressure transmitter adopts the MEMS technology and the advanced glass micro-melting technology to avoid influences on the product caused by the temperature, humidity, mechanical fatigue and medium, thus to improve its permanent stability in the industrial environment. Its pressure sensitive elements are made of imported 17-4PH stainless steel in an integrated way based on the standard explosion-proof structure design with the explosion grade of ExdⅡCT6, which is identified by relevant state authorities. Digital circuits capable of strong RFI & EMI resistance and automatic temperature compensation are installed inside the transmitter.
