2、 Main functions:

Monitoring and protection of the rotational speed of rotating machinery such as steam turbines, industrial steam turbines, water pumps, fans, and motors.

3、 Function Description:

• The measured value and alarm set value can be displayed separately on the LED digital tube.

• Alarm values can be freely set and modified.

• When the alarm setting value is exceeded, the alarm indicator light will turn on, and at the same time, a switch signal will be output on the rear panel to protect the monitored equipment.

• Alarm setting delay adjustment, ranging from 1-60 seconds, to prevent false alarms caused by on-site interference.

• Maintain set parameters and other memory values during power outages.

• Equipped with a current output interface, it can be connected to devices such as computers, DCS, PLC systems, and paperless recorders.

• It has power up and power down detection functions, sensor disconnection detection functions, and cuts off alarm and shutdown output circuits, effectively suppressing instrument false alarms.
