VH991 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.
VH991 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.
VH991 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.
