Product Introduction (英文部分)
The WZP2-130B industrial RTD is a dual-element platinum resistance thermometer designed for reliable temperature measurement in harsh environments. With a standard Pt100 sensing element, it delivers accurate readings across -200°C to +420°C range. The modular assembly structure features replaceable components including stainless steel junction boxes (splash-proof or waterproof) and oxidation-resistant protection tubes, ensuring long-term stability in petrochemical, power generation and metallurgical applications. Its twin independent channels allow simultaneous data transmission to multiple control systems.122
Key Features
This RTD utilizes thin-film platinum technology with class B accuracy (±0.3°C or ±0.005|t|). The hermetically sealed sensing assembly exhibits >100MΩ insulation resistance at 100VDC. Standard 16mm OD protection tubes withstand 1.5x rated pressure, while the 3-wire configuration eliminates lead resistance errors. Customizable insertion lengths (L=XXmm) and process connections (NPT/G螺纹) adapt to various installation requirements. The 5mA current limit ensures minimal self-heating effect during continuous operation.121924
Typical Applications
Ideal for dual-redundancy temperature monitoring in turbines, reactors and pipelines. Compatible with most PLC/DCS systems through direct resistance output or via temperature transmitters. Recommended for steam lines (-30~420°C), hydraulic oil tanks (-50~150°C) and solid surface measurements. Installation notes: For pipe mounting, insert length should reach centerline; avoid excessive vibration locations.41527
