‘Grip Tight’ vibration sensors and accelerometers

MONITRAN have announced that they are to manufacture patent pending ‘Grip Tight’ (GT) versions of their vibration sensors and accelerometers. Using a GT-bodied vibration sensor/accelerometer means the fitting or removal of the sensor to/from its GT stud takes literally seconds, while the mechanical bond, which is essential for the transfer of energy, is unaffected.

Unlike the traditional threaded mounting option, a GT sensor does not have to be screwed on to the stud. This is a major benefit because sensors that have integral cables can be twisted when tightening the sensor on to the stud. According to Monitran, the GT method removes, completely, the risk of sheering the stud-to-machine bond whether it is screw or adhesive.

A GT-bodied sensor also has no hexagonal base, as a spanner is not required for mounting the sensor to its stud. Instead, the tightening of a grub screw draws the base of the sensor down on to the GT stud.

Grip Tight is suited to applications where the vibration sensor is not intended to be a permanent fixture, eg the sensor is taken from machine to machine as part of a regular vibration-based condition-monitoring routine.

Sensors available with the new GT body include: Monitran’s MTN/1100 family, which has AC outputs suitable for vibration analysis; and the MTN/1185 range (DC outputs), which has been designed for machine protection.

The GT studs come with M6/M8 male or female threads as standard, but can be made-to-order to virtually any stud-to-machine mounting method. The grub screw in the sensor has a 4mm thread and Allan keys are supplied.
