Turbine Speed Electric Valve Actuator With 4 Led Digital Display
Speed indicator RZQW-3 speed controller dispaly
turbine speed, impact monitoring device usually display the turbine speed, internal memory function can be an emergency breaker impact "," hit "back" and "high speed" units stored in the instrument, when pressing the corresponding key can be conveniently displayed two ram "hit", "back" movement speed and the highest speed "". The instrument and the corresponding speed analog signal output.
Use :
For the turbine speed monitoring and emergency breaker status monitoring.
Technical parameters
. the input signals: three high resistance CS injection speed sensor (two 11Omm long, a long 75mm).
. display mode: 4 LED digital display
. Measuring range: O to 9999 rpm.
. emergency governor impact detection speed: n > 2000 rpm.
. Speed. The detection accuracy: n < + 1 rpm.
. Analog output: DC4. ZOmA or O IOmA, the load resistance hair 500Q.
. The output precision: level 0.5.
. Warning: usually set speed. The "super 1" 3300 rpm, "super 2" 3420 rpm, are normally open contact. If there are special requirements can be put in order.
. At the relay contact capacity: DC3OV / 7A AC25OV / 7A AC125V / 12A.
. reset function: press "maximum speed of historical instruments alarm status and storage reset" button when the value of all the stored data is cleared.
. Automatic save and historical peak. To see the speed and time of arrival, the instrument set data and record history parameters can be stored for a long time after power off. . the instrument has the power up and power down the false alarm suppression function, after power on 30 45 seconds of a self-locking alarm output.
