Single flange high-precision intelligent 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.

Product Details

Our company independently designs, develops, and manufactures the WLP-0601 series of intelligent pressure transmitters. The central sensing unit uses 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 media 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 and transient voltage protection capability of the electronic circuit. Platinum-grade accuracy reaches ±0.05%, and the unidirectional overpressure can reach up to 70 MPa. Excellent static pressure performance, with optimal static pressure error controllable within ±0.05%/10 MPa, minimal temperature influence, optimally controllable within ±0.04%/10K.

The circuit design adopts a modular design with a microprocessor as the core and supplemented by advanced digital isolation technology, giving the instrument extremely high anti-interference and stability. Using the Hart protocol for communication, it can be remotely operated through a Hart hand-held device or a computer with Hart software installed to complete the configuration of measurement information. Simultaneously, it uses digital compensation technology and compensates the transmitter through a built-in temperature sensor, improving measurement accuracy, reducing temperature drift, and featuring good long-term stability and high reliability. The user-friendly infrared wireless setting and one-button zeroing function meet the safety operation requirements in hazardous environments, making it very convenient to perform quick menu operations and complete all parameter settings, comprehensively improving the performance of the transmitter.
