Explosion-proof Pressure Sensor Hart Pressure Transmitter Pressure Transducer Sensor with Digital Display
Our explosion-proof pressure sensor adopts a high-performance pressure-sensitive chip, combined with advanced circuit processing and temperature compensation technology, to convert pressure changes into linear current or voltage signals. Our company offers two output signal options: analog and RS485, which can be connected to on-site PLCs, configuration software, HMI screens, or industrial controllers. Additionally, our networked data concentrators or monitoring hosts can be used to upload data to our free cloud platform, allowing users to view real-time data, historical records, and alarm logs via a computer or mobile app.
Additionally, the sanitary (flush diaphragm) pressure sensor is based on this pressure sensor but features a welded, sealed isolation diaphragm. This diaphragm sealing device comes in various structural designs, making it particularly suitable for high-temperature, high-viscosity, and crystallized media, as well as environments prone to clogging. It is also ideal for pressure measurement in sanitary and pharmaceutical applications.
