12V Duct Mounting Modbus air temperature and humidity sensor for HVAC system

It adopts standard industrial interface 4~20mA/0~10V/0~5V analog signal output, and can be connected to on-site digital display, PLC, invert, industrial control host and other equipment. The imported temperature and humidity measuring unit has small drift and high precision. The pipeline installation method is convenient for on-site installation. It adopts anti-interference circuit design and can withstand various strong electromagnetic inter preferences such as on-site inverse. The equipment adopts waterproof casing design. The probe filter net uses 25um high-strength stainless steel material to ensure the entry of gas molecules. It also prevents the ingress of dust particles and water droplets, and can be applied to wet and high dust occasions for durability.
