Differential expansion sensor

Differential expansion sensor,Widely used in sectors such as electricity, petroleum, and chemical engineering. By using DO type eddy current sensors, differential expansion can be measured and monitored. Has a level 2 alarm. Equipped with a current output interface, it can be connected to devices such as computers. The monitor adopts a 160 × 80 (mm) universal case, LED digital display, PVC color facial mask and light touch keys. It has beautiful appearance, novel style, reasonable structure, simple installation, stable performance, reliable quality and accurate measurement.

Main function: Display differential expansion measurement value, alarm, and shutdown setting value, which can be displayed separately on the LED digital tube. The alarm function indicates alarm, shutdown, and input signal faults respectively through LED light-emitting tubes. The alarm delay time setting function adjusts the alarm delay time range from 0 to 3 seconds to prevent false alarms caused by on-site interference. ● Self diagnostic function a. Any input system malfunction, such as probe wear, poor wire contact or breakage, can be detected, and the alarm and shutdown output circuits can be cut off at the same time. b. Equipped with power on and power off detection functions, while disconnecting the alarm output circuit, it can effectively suppress false alarms from the monitoring instrument. The output interface is equipped with a 4-20mA current output universal interface, which can be connected to computers and other devices.
