High-temperature gas collection tube level transmitter (1mH2O=9.81kPa ) gas pressure-guided type, used for high-temperature, corrosive liquids, sewage, etc. The transmitter consists of a stainless steel gas collection tube, stainless steel capillary tube, and junction box. The sensor part and signal processing circuit are inside the junction box. The gas inside the gas collection tube immersed in the liquid contacts the medium, and the pressure is transmitted to the sensor through the gas guide tube, avoiding direct contact between the sensor and the measured medium. It is suitable for high-temperature and corrosive applications, effectively solving the difficulties of level measurement for high-temperature corrosive liquids and sewage.
