Our advanced vibration transmitters, or loop powered sensors, are engineered for use with the latest PLC (programmable logic controller), BMS (building management system), or SCADA (supervisory control and data acquisition) technologies, offering sophisticated solutions for condition monitoring and preventative maintenance. The family is available with a variety of different cables.
Key Features:
4-20mA output proportional to velocity
AC ‘g’ for data collection
Various mountings
Sealed to IP65
Flexible cable
Flame retardant to IEC 60332-1
Includes 5 metres of cable (other lengths available on request).
