XJZC-03A/QF Rotary Speed/Ram Monitor （JIANGYIN ZHONGHE ELECTRICALPOWER INSTRUMENT CO., LTD）
Operation Manual
The XJZC-03A/QF speed/impactor monitor receives two critical interrupt signals while measuring speed. It is used to continuously monitor and measure the rotation speed of the rotating mechanism, and record two critical breaking speeds at the same time. The output analog current signal and alarm contact signal can be easily connected with DCS, PLC system and paperless recorder. It can be widely used in electric power, fan, steel, petrochemical and other industries.
XJZC-03A/QF speed/impactor monitor receives two on-site impactor switch quantity signals, the on/off quantity is closed for the impactor to play status signal, and the off for the impactor not to play status signal. It can also receive two high level signals.
一. Use
Suitable for measuring the speed of all rotating machinery. Such as steam turbine.
二. functional characteristics
1.Programmable speed monitor adopts advanced ARM high-performance embedded processor, high versatility hardware design and rich software programming functions, so that the sensor and instrument measurement of linearity, frequency response, temperature drift and anti-interference ability to be greatly improved, plus all parameters are digital setting, making the system measurement accuracy is higher, more reliable protection action.
2. Two configuration modes: The working mode and parameters of the instrument can be set by the upper computer software configuration or the instrument key configuration.
3. Record spikes detected by monitors in real time;
4. Real-time record the speed value of the impactor when it is knocked out and retracted;
5. The parameters of the instrument can be viewed or set by pressing a button. Including: meter number, range, number of teeth, measured transmission coefficient, measured transmission coefficient, alarm value, alarm delay value, alarm relay output, (4 ~ 20)mA corresponding range, etc.
6. The parameters can be stored for a long time after a power failure.
Seven. It has the function of power on and power off suppression (protecting historical data, suppressing false alarm), and self-locking alarm output function within about 10 seconds after power-on.
8. Can output a key phase pulse signal.
9. It has RS485 communication interface and adopts common MODBUS-RTU communication protocol.
