美国UE温度开关UEONE系列电子式温度开关防爆直插式（U.S. UE temperature switch UEONE series electronic temperature switch explosion-proof in-line ）

Significance of the development of UEONE series electronic temperature switch explosion-proof in-line ONE series products of UE temperature switch in the United States The switch products of United Electric Controls (UE) are of high quality in terms of workmanship quality and design concept. Among them, the 1 series products have gathered nearly 80 years of design experience, and its advantages and performance are even higher than other electronic switch products. UE sets a new standard of quality, reliability and versatility for the Series 1 digital electronic pressure and temperature switches. So that it can be used in more harsh or dangerous environments, the advanced self-diagnosis function and digital electronic functions of the 1 series products enable it to be widely used in various industries. UE's 1 series products have a variety of types to choose from, from explosion-proof series, intrinsically safe series to fire-proof series pressure, differential pressure or temperature switches , you can choose according to your own needs. The 1 series also has two full-scale adjustable set points and dead bands, is equipped with a 4-20mA analog output, and has almost absolutely no loose parts design. This feature makes it compared to previous switch designs. It is more suitable for application in different environments. With no loose parts, the UE1 series can be used in environments with high vibration and shock frequencies. For the upgrade of user's factory equipment, the 1 series is designed with various power types to choose from. It has 2-wire DCS system power supply and analog loop power supply mode, and can also provide external power supply. The maximum load can reach 10 amperes 280 VAC. The following are some application cases: 1. Pumps and compressors - start/stop, optimization, shutdown;2. Lubrication monitoring - oil tank temperature, bearing pressure, pre-maintenance;3. Hydraulic oil pressure - high pressure monitoring, Emergency shutdown;4. Filter monitoring - automatic flushing, display blockage and abnormal conditions, provide flow value;5. Safety system - complete safety level 1&2, alarm and shutdown, on-site alarm switch, fast response time;6. Renovation and upgrading of factory equipment - upgrading of power plants and sewage treatment, replacing mechanical switches.ONE series temperature switch characteristics Housing: 4X/IP66, aluminum epoxy coating.
