Monitran launches low-profile accelerometer
The MTN/1100SHC accelerometer is specifically designed to provide effective vibration and shock monitoring in a wide range of OEM, industrial and machinery applications, where space is limited.
The probe is positioned without making contact with the shaft but near enough to measure the gap.
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 24V DC input and the 4-20mA output operating on a two-wire loop-powered circuit.
The driver has a linearity of 1% 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 0-2 to 12mm.
