WTR10-E Temperature and Humidity Transmitter with RS485 Output Supports for MODBUS-RTU Protocol

WTR10-E Temperature and Humidity Transmitter with RS485 Output Supports for MODBUS-RTU Protocol

Description:
WTR10-E temperature and humidity transmitter uses high-precision digital sensor, with reliable performance, high precision, small annual drift and fast response. RS485 bus technology is used. Based on the industrial protocol for MODBUS-RTU, it realizes low-cost temperature and humidity status online monitoring. Thus, it is a practical integrated sensor for you.

Features:
- High-precision digital temperature and humidity sensor is of high sensitivity, good stability, and automatic temperature compensation throughout the process.
- MCU adopts professional leading high-quality low-power chips (for STC) to ensure processing power and stability.
- With standard RS485 output, it can realize long-distance communication.
- In the industrial field, it is suitable for various standards for Modbus-RTU communication protocol.

Technical Parameters:
- Power supply range: DC9V~40V (1: With lightning protection function.) 2: There is a power protection function and there is no need to distinguish between positive and negative poles. Note: RS485A/RS485B needs to be connected correctly and reverse connection is not allowed)
- Power: < 0.1W
- Measuring range: temperature: -40°C to 85°C; Humidity: 0~100%RH
- Measurement accuracy: temperature: ± 0.3°C, resolution: 0.01°C; Humidity: ±3.0%RH, resolution: 0.024 RH
- Response time: 2s
- Communication output interface: RS485
- Baud rate: can be set to 2400, 4800, 9600 and 19200 (set baud rate command BPS=0: baud rate 2400; BPS=1: baud rate 4800; BPS=2: baud rate 9600; BPS=3: baud rate 19200. The default baud rate is 9600)
- Byte format: 8 data bits, 1 stop bit and no need to check
- Communication protocol: for Modbus-RTU
- The correspondence address can be set: 1--253, the address defaults to 1 [set address command ADR=1 (address 1); ADR=2 (Address 2); ADR=3 (Address 3); And so on]
- Installation: mounted to rail
- Shell material: ABS

Application Fields:
The temperature and humidity transmitter can be used in industrial site measurement, telecommunication base stations, production workshops, warehouses, agricultural greenhouses, hospitals, laboratories, hotels, temperature and humidity monitoring, on-site measurement and others.

Installation Method:
WTR10-E is a high-precision temperature and humidity transmitter, with beautiful and compact appearance. Standard rail structure design makes it easy to install. It can be installed indoors and to ceilings.

Attention:
1. The product is not suitable for long-term condensation and chemical pollution environment to prevent chemical reagents, oil, dust, etc. from directly invading the sensor. Remember not to do cold and thermal shocks.
2. Please check carefully before use to ensure that the wiring is correct. The positive and negative terminals of the power supply can be connected reversely, because the power supply of this product does not need to distinguish between positive and negative terminals. The communication line needs to be connected correctly according to RS485A and RS485B, otherwise it will not be able to communicate.
3. Avoid heat transfer and temperature difference between the test areas to avoid inaccurate temperature and humidity measurement.
4. Installed in an area with a stable environment to avoid direct lighting. Stay away from windows and equipment such as air conditioning, heating devices, etc., and avoid going directly to windows and doorways.
5. Try to avoid high-power interference equipment (such as frequency converter, motor, etc.) to avoid inaccurate measurement.
6. If you want to disassemble the product, you must disconnect the power supply first, and then disassemble it.
7. This transmitter is used indoors, to prevent water from entering the transmitter to avoid damage.
8. If you encounter some problems during use, please not disassemble or repair the product. Please contact our customer service staff to solve the problems you encounter under the guidance of engineers. Thank you!
