Description

4-20mA Vibration Transmitters

The same 4-20mA technology used to measure temperature, pressure, flow and speed can also be extended to measure the overall vibration of rotating machines with Vibration Transmitters.  Adding Vibration Transmitters or Vibration Probes to the machine provides a critical measure of the machine’s health through this machine monitoring. Trended Overall Vibration values can be used to identify changes in balance, alignment, gears, bearings and many other potential faults.

Today’s modern control systems offer flexibility in Vibration Transmitters or Vibration Sensors selection and use standard 4-20mA current loops for most applications. 4-20mA loops are inherently low in noise and signals can be transmitted over very long distances. Vibration Transmitters or Vibration Probes outputs are proportional to current with 4mA representing a zero level and 20 mA a maximum level over the chosen range.

All our loop powered vibration probes conform to a lifetime warranty on material and workmanship.

Our Vibration Transmitters range includes:

LP200 & LP300 Series. 4-20mA Loop Power Output Vibration Transmitters.

  • Peak & RMS outputs available
  • 4-20 mA output proportional to velocity
  • 4-20 mA output proportional to acceleration

Loop Power Vibration Sensors/Transmitters like the LP200 Series (4-20 mA proportional to vibration measured in velocity) or LP300 Series (4-20 mA proportional to vibration measured in acceleration) can be mounted on the machine and added to the control loop. As the overall vibration of the machine changes, the 4-20 mA output will vary proportionally.

LP401, LP402 & LP404 Series . Dual Output, Loop Power Sensors Vibration Transmitters

  • 4-20 mA Output & Dynamic Vibration Outputs
  • Outputs to PLC, DCS, SCADA

Dual Output Loop Power Sensors also provide a secondary output of dynamic vibration. These secondary outputs could be acceleration or  velocity and are combined in three different loop power sensor configurations:

  • LP401 Series – Overall Velocity (4-20 mA), and Dynamic Velocity (100 mV/in/sec)
  • LP402 Series – Overall Velocity (4-20 mA), and Dynamic Acceleration (100 mV/g)
  • LP404 Series – Overall Acceleration (4-20 mA), and Dynamic Acceleration (100 mV/g)

LP232, LP234, LP332 & LP334 Series – Dual Output, Loop Power Sensors Vibration Transmitters

  • 4-20 mA Vibration Output
  • Temperature Output: 10mV/°C (VDC)
  • Outputs to PLC, DCS, SCADA

The Dual Output 4-20 mA Vibration and Temperature Sensor is available with an acceleration or velocity output in combination with a 10 mV/°C temperature output. Power is supplied by the 4-20 mA current loop. The overall vibration is proportional to 4-20 mA and can be used with a PLC, DCS, or SCADA for monitoring the vibration amplitude. The DC voltage output is proportional to temperature from -40°C (0.10 VDC) to +85°C (1.35 VDC). This output can be trended in voltage to monitor the change in temperature of the machine.
