Frequently Asked Questions

What is the communication protocol for this sensor?

The sensor uses an RS485 serial interface configured for the Modbus RTU protocol. This allows it to be connected in a multi-drop network with other Modbus devices, such as PLCs, SCADA systems, or building automation controllers, over distances up to 1200 meters.

What is the required power supply for the RS-WS-N01-9TH-EX?

The sensor operates from a wide-range 10 to 30V DC power supply. This flexibility makes it compatible with common 12V or 24V DC systems used in industrial and building automation. Its maximum power consumption is only 0.1W.

How do I install this sensor in an HVAC duct?

The sensor is designed for duct mounting. It typically requires a mounting hole in the duct wall. Ensure the sensing element is fully exposed to the air stream and that the unit is securely fastened. Always follow local HVAC codes and the manufacturer's installation guidelines for optimal performance.

What is the accuracy and long-term stability of this sensor?

The sensor provides a temperature accuracy of ±0.5°C and a humidity accuracy of ±3% RH. It features excellent long-term stability, with a typical drift of ≤0.1°C per year for temperature and ≤1% RH per year for humidity, minimizing the need for frequent recalibration.
