Pressure Transmitter PCM113
Product overview
The pressure seat of the PCM113 transmitter is processed using a 17-4PH stainless steel single piece integrated structure. The integrated stainless steel structure makes its overload performance much higher than commonly used sensor materials such as ceramics and diffused silicon. The pressure connection has no welds, no silicone oil or other organic substances, and good sealing performance. The sensitive components of the sensor adopt glass micro melting technology, which greatly improves the high temperature and vibration resistance of the sensor, ensuring the long-term stability, reliability, and durability of the transmitter in harsh industrial environments. In the standard purification production process, all parameters are strictly controlled, and the entire product has undergone strict testing and aging screening of components, semi-finished products, and finished products, with stable and reliable performance.
The PCM37 pressure transmitter can be widely used in fields such as automotive air conditioning, braking, oil, and pressure monitoring of onboard CNG pressure tanks.
