I. WZPJ Integrated Temperature Transmitter
An integrated temperature transmitter typically comprises a temperature sensor (thermocouple or resistance thermometer) and a signal converter (transmitter module), compactly housed together within a protective sheath. It directly transforms the physical temperature signal into a standard 4–20 mA current output (or outputs via protocols such as RS‑485 or HART), achieving “sensing + transmission” in a single step.
II. Key Features
Features Explanation Integrated structure The sensor and transmitter are highly integrated with no external circuitry, making installation simple and ensuring high reliability Two-wire output Standard 4–20 mA current signal, with strong anti-interference capability, suitable for long-distance transmission (up to 1000 meters) Wide measurement range Resistance thermometer temperature measurement range: -200℃~500℃; thermocouple temperature measurement range: 0℃~1300℃, meeting the requirements of various operating conditions High accuracy class Accuracy can be >±0.2%FS, ±0.2%FS, or ±0.5%FS, allowing flexible selection based on actual needs Multiple connection methods Supports threaded connections (M27×2, G1/2, etc.), flange connections, and clamp connections, suitable for various installation scenarios On-site display optional Optional LCD display or LED digital tube display, providing clear on-site readings at a glance High protection rating Standard protection rating IP65; IP68 available; dustproof and waterproof, suitable for harsh outdoor conditions Explosion-proof certification Available in intrinsically safe (Ex ia IIC T6) or flameproof (Ex d IIC T6) versions, suitable for flammable and explosive environments III.
