High-temperature pressure transmitters are designed for harsh industrial environments such as petrochemical plants, metallurgy, steam systems, melt extrusion equipment, pneumatic conveying, and pharmaceutical machinery. Models like STG10, STG27, STG33, and STG40 cover medium to high temperatures up to 350°C with various pressure and media compatibility.
The STG33 melt pressure transmitter can withstand up to 350°C at the diaphragm, making it suitable for plastic extrusion, melt processing, and high-temperature industrial systems with stable and repeatable performance.
They use corrosion-resistant materials such as 316L stainless steel, titanium, tantalum, or Monel, combined with diaphragm isolation structures to resist acids, alkalis, salt mist, and aggressive media.
STG27 is designed for medium-to-high temperature applications up to around 300°C, mainly for steam and hydraulic systems, while STG33 and STG10 are intended for higher temperatures, melt processes, and stronger corrosion environments with enhanced thermal protection.
They typically support 4–20mA analog output, and some models also offer 0–10V, 0–5V, and RS485 Modbus-RTU. For example, STG10 supports multiple signal outputs for easy integration with PLC and automation systems.
Yes, certain models such as STG10 are designed with explosion-proof capability, meeting CT4/CT6 or intrinsic safety standards, suitable for hazardous environments like oil and gas and chemical industries.
Selection depends on temperature range, medium type, pressure range, output signal, and installation. For melt applications choose STG33, for steam and general high temperature choose STG27, and for corrosive high-temperature environments choose STG10.
Yes, OEM customization is available, including pressure range, output signals, materials (316L, titanium, tantalum, etc.), process connections, and protection levels to meet various industrial integration requirements.
