The Aosong AW3020A is a current-type temperature and humidity transmitter designed for industrial applications. It features high-precision capacitive digital sensors with a wide measurement range and strong anti-interference capabilities. The device supports real-time display of monitoring values, internal alarm functions for high/low limits, and outputs an industrial standard 4~20mA signal. This manual is written in Chinese.
| Temperature Measurement Range | -20~60℃ (External probe: -40~80℃) |
|---|---|
| Humidity Measurement Range | 0~99.9%RH |
| Measurement Accuracy (at 25℃) | ±0.3℃/±2%RH |
| Resolution (Temperature) | 0.1℃ |
| Output Signal | 4~20mA current signal |
| Operating Voltage | 20~36VDC (USB 5V) |
The load impedances RL1 and RL2 must be less than 400Ω to avoid unexpected errors in the current signal.
Errors may occur if the device is placed in an environment for too short a time, near heat/cold sources, or directly in sunlight.
