Wireless communication pressure transmitter

Our company independently designs, develops, and manufactures the WLP-0601 series of intelligent pressure transmitters. The central sensing unit adopts globally leading high-precision silicon pressure sensor technology and packaging processes. The single-crystal silicon pressure sensor is located at the top of the metal body, away from the medium contact surface, achieving mechanical and thermal isolation; the glass-sintered integrated sensor leads achieve high-strength electrical insulation with the metal substrate, improving the flexibility of the electronic circuit and its ability to withstand transient voltage protection. Platinum-grade accuracy reaches ±0.05%, and the unidirectional overpressure can reach up to 70 MPa. Excellent hydrostatic performance, with hydrostatic error optimally controllable within ±0.05%/10 MPa, minimal temperature influence, optimally controllable within ±0.04%/10K.
