HS-420 Transmitter 4-20mA velocity- 2 Pin MS

Vibration Monitoring with Hansford Sensors

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
  • Sealed to IP68
  • Various mountings

Typical Applications:

Fans, pumps, motors, gearboxes, compressore, centrifuges, conveyors, Air handlers, rolls, dryers, presses, cooling, VAC, spindles, machine tooling, process equipment
