MCS-11 microcomputer speedometer

Physical indicators:

Overall dimensions:

Dimensions: 160 × 80 × 160mm

Hole size: 152 × 74mm

Environmental indicators:

Temperature: Operating temperature -20℃To+60℃Storage temperature -30℃Up to+70℃。

Relative humidity ≤ 90%There are no corrosive or strong magnetic fields around.

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.

Main functions:

Monitoring and protection of the rotational speed of rotating machinery such as steam turbines, industrial steam turbines, water pumps, fans, and motors.Online monitoring of large rotating mechanical equipment such as steam turbines, water pumps, motors, fans, blowers, compressors, coal mills, oxygen concentrators, crushers, and separation machinery. The customer base is distributed in various industries, including petroleum, chemical, power, steel, pharmaceuticals, etc.

Easy installation and maintenance, precise measurement, effective suppression of false alarms, reliable stability, and quality assurance
