Introduction:

Our transmitter is professionally used for pipeline temperature and humidity measurement. 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.

FEATURES:

1. Temperature and humidity acquisition, 4 ~ 20mA, 0 ~ 10V, 0 ~ 5V analog signal output;
2. -4080C, -2080C, -4060C, 050C and other temperature range dialing settings, the site can be freely changed, other ranges can also be customized;
3. Temperature accuracy 0.3 C, humidity accuracy 3% RH, high precision, low drift;
4. The terminal block adopts the military-grade spring-type screw-free terminal, which can be connected by one press and one plug. Even if there is no screwdriver, the line can be quickly connected, and the wire diameter can be adjusted to 0.3~2.0mm2;
5. Using special EMC anti-interference device, the site can withstand strong electromagnetic interference, industrial grade processing chip, wide range of use;
6. Support AC and DC power supply, DC 10 ~ 30V wide voltage range power supply, AC power supply voltage 24V 10%, power input without positive and negative points, can be applied to both four-wire and three-wire connection;
7. The flange has a high-quality silicone sealing ring, which ensures the tightness between the equipment and the exhaust pipe during installation, greatly reduces the outflow of gas in the exhaust pipe, and ensures the accuracy of data measurement to the utmost extent.
