Axial Displacement Transmitters

MET991 Axial Displacement Transmitter - Loop Powered

Brief introduction

MET991 two-wire shaft displacement transmitter converts the peak value of displacement into the industrial standard signal of 4 to 20mA, providing displacement monitoring protection and alarm for machinery.

■ MET991 two wire axis displacement transmitter application description

MET991 two-wire axial displacement transmitter is mainly used to test the axial displacement of the rotating shaft of the machine. It can be very convenient and industrial field existing PLC or DCS system directly connected, using 4 to 20mA loop power supply, does not need additional power distribution and instrument conversion, can be simple and convenient, low cost and effective for rotating equipment monitoring protection.

Usually, the axial displacement measurement is installed in the axis direction of the axis of rotation, measurement.

MET991 two-wire axial displacement transmitter, is essentially an eddy current sensor, its probe can measure the displacement change between the measured object (metal) and the probe. When the distance between the measured object and the probe changes, the transmitter can convert the shift change into a current signal of 4 to 20mA.

MET991P Axial Displacement Transmitter - 3 Wires

Brief introduction

MET991P three-wire shaft vibration transmitter converts the peak value of vibration displacement into 4 to 20 mA industry standard signals, providing vibration monitoring protection and alarm for machinery.
