Eddy current probe driver has direct PLC
interface
The latest MTN/ECPD-2 series driver for use with the range of Monitran inductive eddy current proximity probes has a 2 wire 4-20mA output which will interface directly with PLCs
The latest MTN/ECPD-2 series driver for use with the range of Monitran inductive eddy current proximity probes has a 2 wire 4-20mA output which will interface directly with PLCs Eddy current probes are used extensively in industry to monitor rotating shaft alignment on such equipment as pumps, turbines, centrifuges, etc The probe is positioned without making contact with the shaft but near enough to measure the gap

Simple pump vibration monitoring probes
The latest eddy current probes from Monitran, for non-contact vibration monitoring of pumps, have been designed to offer reliable AC or DC displacement measurement, with a 4-20mA output
New vibration sensor has choice of output signals
A new vibration sensor is designed to meet the requirements of building service managers, who are using vibration monitoring systems to help provide trouble-free utility services for their workplace
Any wear in bearings or other misalignment will be seen by the probe whose output will change in proportion.
This output is applied to the MTN/ECPD-2 where it is conditioned and converted to a 4-20mA signal for direct interface into a PLC.
The PLC can then be used to initiate alarms or control or stop the machinery in order to avoid danger or prevent damage to personnel or plant equipment.
The eddy current probes are constructed in stainless steel with overbraided cable for operation in tough conditions and connect to the driver via a SMC miniature coaxial connector.
An alternate version, the MTN/EPHD080, is also available where the complete system of probe and driver are constructed as one unit.
Electrical connection is by screw terminals for the 24VDC input and the 4-20mA output operating on a 2 wire loop-powered circuit.
The driver has a linearity of 1 percent nominal, a frequency range of 5Hz to 1kHz, and can be matched to all other Monitran probes to give a choice of probe style, and differing measurement ranges from 0-2mm up to 12mm.
