4-20mA Duct Humidity Temperature Sensor for HVAC Building Management
The Duct Type Humidity Temperature Transmitter measures temperature and relative humidity in air ducts. The probe filter at the bottom of the duct temperature and humidity sensor is made of 25um high-strength stainless steel material, which can not only ensure the entry of gas molecules but also prevent the entry of dust particles and water droplets. 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. Besides, the equipment adopts waterproof casing design. Pipeline humidity and temperature transmitter for the long distance transmission, using 4-20mA industrial universal interface, direct access to a variety of display devices, to achieve humidity and temperature monitoring.
This duct sensor is designed and developed specifically for HVAC systems. It has the characteristics of high accuracy and low cost. It is an ideal instrument for measuring the relative humidity and temperature of the air. It can provide customers with reliable temperature and humidity measurement solutions. This design shell reduces the installation cost to the greatest extent, reduces the workload on site, and improves the product's anti-pollution and anti-condensation performance, so as to ensure that the error is minimized during the work process.
Moreover, the flange plate of this sensor is equipped with a high-quality silicone sealing ring, which can ensure the sealing between the equipment and the exhaust pipe during installation, greatly reduce the outflow of gas in the exhaust pipe, and ensure accuracy of data measurement to the greatest extent. The top of the duct temperature sensor can be equipped with a high-brightness color LED display to ensure that the displayed value can be seen clearly in a dim place. Therefore, if you require to view the reading at the device, you can customize this sensor with display.
