High Temperature Precision, Right Before Your Eyes: The New Instrument YW-140G Intelligent Digital Display High-Temperat

In industrial processes such as petroleum refining, high-temperature steam, and food sterilization, media temperatures often soar above 200°C. The challenge for pressure measurement lies not only in the temperature resistance of the sensing core but also in enabling operators to read data intuitively and accurately on-site. Traditional remote-mount instruments often lack local displays, causing inconvenience for inspections and debugging. Xi'an Xinyi Instrument Technology Co., Ltd. precisely addresses this need with the launch of the YW-140G Stainless Steel High-Temperature Pressure Transmitter. This innovative product integrates high-temperature measurement capability with on-site digital display, utilizing an imported high-temperature resistant chip and an efficient heat dissipation structure design to reliably measure media temperatures up to 300°C. Equipped with a 5-digit LCD display, it allows engineers to clearly read real-time pressure right next to boilers or sterilization tanks. With its all-stainless steel construction, IP65 protection rating, and exceptional long-term stability (≤0.2% FS/year), the YW-140G provides an intelligent solution that combines accuracy and convenience for demanding high-temperature applications in industries like petroleum, chemicals, boilers, and food & pharmaceuticals.

1. Integrated Heat Dissipation Design, Confidently Facing 300°C Challenges
   The YW-140G is specifically engineered for high-temperature environments. Its core features a 316L stainless steel isolation diaphragm and an imported high-temperature resistant sensor chip, with a specially designed efficient heat dissipation structure between the pressure port and the electronics housing. This design effectively isolates heat conduction, ensuring internal electronic components operate within a safe temperature range, enabling the transmitter to directly measure process media up to 300°C. It perfectly handles pressure monitoring in scenarios involving boiler steam, hot oil, and high-temperature reactors.

2. Integrated digital display, easy to read on-site readings at a glance
   Unlike ordinary non display pressure transmitters, YW-140G integrates a clear 5-digit LCD display screen at the top. This allows on-site operators to directly read the current pressure value next to the equipment without the need for additional tools or handheld terminals, greatly facilitating daily inspections, on-site debugging, and troubleshooting. The screen displays clearly, adapts to outdoor lighting environments, and enhances the safety and convenience of operation.

3. Durable and sturdy design, suitable for various harsh environments
   The transmitter body adopts a fully stainless steel structure, combined with a sturdy aluminum alloy junction box, with an overall protection level of IP65, which can effectively resist dust, moisture, and rain, suitable for outdoor or humid industrial site installation. The product undergoes strict testing and aging screening from components, semi-finished products to finished products, ensuring long-term stability of better than 0.2% FS/year, and can withstand mechanical vibrations of 20g (20-5000Hz). It can also work stably near vibration sources such as compressors and pumps.
