Product Details
The integrated temperature and pressure transmitter's central sensing unit utilizes globally leading high-precision pressure sensor diaphragm and bellows technology and packaging processes. The pressure sensor diaphragm and bellows are 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 from the metal substrate, improving the flexibility of the electronic circuit and its ability to withstand transient voltage protection. The temperature sensing unit uses high-performance, high-reliability imported platinum resistance or thermocouples, and is packaged with a stainless steel metal probe. It uses corrosion-resistant cables with aviation connectors to connect to the display head, facilitating easy plug-and-play disassembly.
This product uses a modular design in its circuit design, with a microprocessor at its 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 via a Hart handheld 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 of hazardous environments, making it very convenient to perform quick menu operations and complete all parameter settings, comprehensively improving the performance of the transmitter.
