This device is suitable for various applications including SMT industry monitoring, cold storage, pharmaceutical GMP systems, and environmental monitoring. The transmitter uses a separate probe design compatible with multiple external high-precision sensors. This manual is written in Chinese.
| Temperature Measurement Range | 0℃~+50℃ |
|---|---|
| Measurement Accuracy | ±0.5℃ |
| Communication Port | 4-20mA |
| Power Supply | DC12V-24V |
| Storage Temperature | -40 - 85℃ |
The calculation uses V= A*(I-4) /(20-16), where I is measured current and A is the range.
The device requires a DC voltage between 12V and 24V for operation.
