JWB-K series temperature transmitter is a temperature transmitter designed with advanced circuit module integration technology, which can be connected with different temperature sensors to realize the measurement of environmental temperature and medium, and output standard current signal or voltage signal. The transmitter is small, light, easy to install and portable, with stable and reliable performance; it adopts proprietary circuit with good linearity, strong load capacity, long transmission distance and strong anti-interference ability. It can be widely used in temperature measurement in electric power, petroleum, building materials, scientific research and other industries.
This manual introduces the JWB series temperature transmitters developed by Beijing ColliHigh, describing their compact design, stable performance and suitability for industries such as power, petroleum, building materials and research. It explains the series variants (K, H, B, D, TT4C) and their specific mounting options.
The document details technical parameters (power supply, output types, accuracy, load capacity), physical dimensions, wiring diagrams for each variant, and important safety precautions for installation and operation. This manual is written in Chinese.
| Power Supply | DC24V |
|---|---|
| Current Output | 4 mA ~ 20 mA |
| Load Capacity (current output) | ≤500 Ω |
| Environmental Temperature Range | 0 °C ~ 50 °C |
The transmitter can provide either a 4 mA ~ 20 mA current output or a 0 V ~ 5 V voltage output.
The device is powered from a DC 24 V source.
If the transmitter has no sensor, a resistor equivalent to the sensor must be connected before power‑on to avoid an open‑circuit condition.
