Product Description
The explosion-proof oxygen temperature and humidity transmitter designed by our company is used for the detection of oxygen temperature and humidity in the air. When the oxygen concentration exceeds the preset alarm value, an audible and visual alarm signal will be issued to remind users to take safety measures in time. The transmitter adopts the original high-quality temperature and humidity sensor imported from Switzerland, and the imported first-line big brand electrochemical oxygen sensor. The sensor has the characteristics of high measurement accuracy and strong anti-interference ability, which ensures the excellent measurement performance of the product. With large-screen LCD display, protection grade IP65, explosion-proof mark: Ex d IIC T6 Gb, it can be used in harsh outdoor environment.
The equipment adopts wide voltage 10-30V DC power supply, 485 signal output, standard Modbus-RTU communication protocol, ModBus address can be set, baud rate can be changed, the communication distance is up to 2000 meters.
