HZS-04T-S wall-mounted reverse tachometer (WT－φ16-L80 )Integrated eddy current sensor
HZS-04T-S wall-mounted reverse tachometerOverview
Rotating machinery such as industrial feed water pumps usually does not allow reverse rotation. When reverse rotation occurs, immediate measures should be taken. The intelligent reverse tachometer is designed for this purpose. It is equipped with two eddy current sensors and installed at the required Angle. It can not only measure the rotational speed of the equipment but also monitor the rotation direction of the shaft, and provide alarm and protection signals when the equipment reverses.
Function Description
l Achieve intelligent processing: Alarms, dangers, number of teeth, and range values can be set through the panel keys
It features alarm, danger and reverse alarm functions. The panel is indicated by indicator lights, and the rear panel has terminal blocks providing relay output.
The alarm delay adjustment range is 0.1 to 6 seconds to prevent false alarms caused by on-site interference
There is a current output terminal on the rear panel that is proportional to the rotational value for record output

Installation and wiring
1. Installation
Insert the sensor into the installation bracket, ensuring that the distance between the probe and the speed measurement gear is between 0.5 and 1.5mm, and then tighten the fastening nut.
2. Wiring
Under normal circumstances, the cables of eddy current sensors use high-temperature three-core shielded wires.
WT-φ16-L80 wiring method: ① Green: Signal output (IN+) ② White :COM (-)
③ Red :+12V (UT) ④ Metal wire: Shielded
Note: This wiring method is for reference only. If it does not match the cable label, please refer to the cable label!
