CAT1 split-type Wireless Temperature and Pressure Transmitter

Fearless Deep Well · Dual-Sensor Integration · The Ultimate Isolation Solution for Industrial Measurement and Control

The split-type wireless temperature and pressure transmitter features a physical separation design between the sensor and the transmitter module, connected via an industrial-grade wireless HART protocol. It integrates simultaneous measurement of dual parameters: temperature (RTD/thermocouple) and pressure (piezoresistive/capacitive). The sensor can operate in extreme environments ranging from -200°C to 1000°C, while the transmitter module is deployed in a safe zone. Combined with dual-battery power supply and LoRaWAN/5G dual-mode transmission, this design completely eliminates wiring risks and signal interference in scenarios such as deep wells in reactors, rotating equipment, and enclosed spaces, providing an intrinsically safe, maintenance-free monitoring solution for high-risk processes.

Conquer six extreme scenarios
✅ Ultra-high temperature reactors: Insertable sensors withstand 1000°C molten salt/metal liquid, wireless modules are installed on the outer wall to protect against heat radiation.
✅ Deep wells/underground pipelines: Sensors withstand 100MPa pressure, transmitters transmit wirelessly at the wellhead, eliminating moisture and corrosion.
✅ High-speed rotating equipment: Non-contact wireless transmission resists centrifugal interference (>10,000rpm).
✅ High-radiation areas: Sensors are deployed in nuclear waste pools, with transmitters remotely reading data from a safe zone
✅ Micro-sealed containers: 3mm-diameter sensors are implanted in micro-reactors, with wireless modules mounted externally
✅ Mobile equipment: Hydraulic systems in construction machinery, zero data loss in vibrating environments

Ending a decade of safety pain points:
✦ High-temperature cable burnout ✦ Rotating equipment slip ring failures ✦ Leakage risks from openings in sealed containers ✦ Manual inspections in high-radiation zones
