SMART TWO WIRE VIBRATION SWITCH-NEW CLASS OF MONITORING DEVICE
This smart, two-wire vibration switch is a new type of device for machinery condition monitoring and protection. It has been designed to be a cost effective tool for generating an alarm or initiating shutdown of small to medium-size machinery, such as electrical motors, pumps, cooling towers, fans, and compressors. The vibration switch is designed like universal unit, including an acceptability of any supply voltage from 24 till 265 VAC or VDC, and it is field configurable thru the same two operation wires (pins) by using special USB programmer. Additionally to programmability, vibration threshold of the device is adjustable electronically by external magnet sensor activation technology (Patent and Trademark pending). Construction of the devise provides possibility of electrical connection in series or/and in parallel several units for different applications. The device is entirely self-contained within hermetically sealed, stainless steel housing. The units appearance is very similar to industrial accelerometer and has the same simplicity of installation. In the same time it is based on true RMS vibration velocity measurements switch providing virtual universal compatibility with any type of load, relay, monitoring system, or control device.
