ONE系列UE温度开关美国UE温度开关带温包（ONE series UE temperature switch US UE temperature switch with temperature bulb and capillary ）

ONE series UE temperature switch US UE temperature switch with temperature bulb and capillary self-diagnosis monitoring performance of ONE series UE temperature switch Mechanical switches do not have self-test function, they are very passive instrument switches, all 1 series products have IAM (I'm at work) self-diagnosing capability, able to detect problems before there are problems in the operation of the switch. When the switch is about to detect a fault, and the original 4-20mA analog output exceeds the range of 4 and 20mA, the switch provides remote fault indication, and the fault report will be displayed on the display. This intelligent and reliable IAM detection enables Series 1 products to comply with SIL-2 requirements, providing a higher risk assurance mechanism than those used in SIS transmitters. ONE series explosion-proof temperature switch features: shell: 4X/IP66, aluminum epoxy coating. Dial: Polycarbonate pressure-sensitive keypad and display resistant to UV damage. Cover: Epoxy coated aluminum with tempered glass interior (Ex series models only). Electrical interface: 1/2"NPT internal thread stainless steel interface; 3/4"NPT external thread cast aluminum interface (only explosion-proof series models). Setpoint & Deadband: User set, 100% full scale adjustable. Memory: Equipped with non-lost data memory to ensure the security of programming and data. Effective transmission distance: 2W2D/2X2D and 2W3A/2X3A can reach an effective transmission distance of 2000 feet.
