Production of high-precision DF9011 precision transient tachometer

DF9011 Precision Transient Speedometer

Functional Description

Query the basic setting parameters of the instrument;

The instrument provides a DC power supply with overvoltage protection and short-circuit protection to the sensor;

Overspeed and zero speed over limit discrimination of monitoring values, status indication, and output;

The instrument has three control relays, which can achieve multi-level protection and zero speed control.

The range, alarm, danger, and number of teeth can be set and changed arbitrarily.

DF9011 Precision Transient Speedometer

Product Features

To ensure the high reliability of instruments, the design and manufacturing concept of monitoring PLC is adopted.

Built in microprocessor for continuous self diagnosis of sensors, instrument circuits, and software.

E2PROM automatically memorizes instrument operation status data.

A truly multifunctional and intelligent monitoring instrument

By using the front keyboard to set overspeed alarm, zero speed alarm, and tooth count on the speed gauge, it is easy to monitor and protect various speed quantities
