Product Introduction
The terminal block uses military-grade spring-type screwless terminals, just press and plug to connect wires. Even without a screwdriver on site, wiring can be completed quickly, and it supports wire diameters of 0.2–1.5 mm.2；
Multiple temperature ranges such as -40～80℃, -35～35℃, -35～50℃, 0～50℃ can be set via DIP switch, and can be freely changed on site. Other ranges can also be customized;
Adopts dedicated EMC anti-interference components, can withstand strong electromagnetic interference on site, industrial-grade processing chip, wide application range;
The flange is equipped with a high-quality silicone sealing ring, which ensures the sealing between the device and the exhaust duct during installation, greatly reduces the leakage of gas in the exhaust duct, and ensures the accuracy of data measurement to the greatest extent.
