GW-Y2 Oil Motive Motor Travel Monitoring InstrumentDetailed product description：

1、 Introduction
GW-Y2 hydraulic engine stroke monitoring instrument, equipped with YW-02 linear displacement sensor, can measure the valve position opening of various rotating machinery. The starting valve, power limiter, synchronizer, and oil motor stroke of the steam turbine generator set reflect the working condition, load size, and operating efficiency of the unit. It is necessary to connect the oil motor stroke monitoring instrument with the oil motor sensor for accurate monitoring and measurement

2、 Main functions
display function
The measured stroke value, I value alarm, and II value alarm set value of the hydraulic engine can be displayed separately on the LED digital tube, with a 4-digit digital tube display and the first digit being the symbol bit.
alarm function
There are two levels of alarms, and users can set the alarm value according to their needs. When the stroke of the hydraulic engine exceeds the alarm set value, the corresponding alarm indicator light on the front panel will light up, and the monitoring instrument will output a switch signal on the rear panel to protect the controlled equipment.
Record output
Equipped with a 4-20mA current output interface, it can be connected to devices such as computers, DCS, and PLC systems.
