CAT1 Wireless Temperature and Pressure Transmitter

Dual-channel synchronization · Wireless freedom · The ultimate evolution in industrial measurement and control

The wireless temperature and pressure transmitter employs high-precision silicon piezoresistive + platinum thin-film RTD technology, integrated with an industrial-grade wireless IoT system (LoRaWAN/NB-IoT/5G), enabling millisecond-level synchronous measurement of both pressure and temperature parameters. The transmitter features an all-welded stainless steel structure, combined with an ultra-low power wireless architecture and AI self-diagnostic algorithms, completely eliminating wiring constraints and signal interference in applications such as rotating equipment, deep wells, and explosion-proof zones. It provides a maintenance-free, intrinsically safe monitoring solution for the energy, chemical, and manufacturing industries.
