The sensor offers a standard IEPE type interface to enable easy integration with existing plant protection and monitoring equipment. Furthermore, the VEL/GLF provides advantages over traditional piezo-electric based velocity vibration sensors which are susceptible to many forms of interference in low frequency applications that can result in spurious readings and alarms.
The VEL/GLF offers high noise immunity due to the low impedance electro dynamic nature of the sensor assembly. In addition to the filtering of high frequency events - and since no electronic integration is required - the design is immune to the saturation problems that impair the reliability of piezoelectric devices.
