RDZW-2N-A05-B01-C02-D02-E01 Axial Displacement Monitor
The input signal of the monitoring instrument comes from the DWQZ series eddy current sensor. The amount of axial position change of the inner rotor relative to the fixed part of the rotating machine is mainly measured.
The main function
With power and power-down protection.
With zero confirmation function to ensure the instrument zero and mechanical zero
Keep the same.
Input signal abnormal failure indication function, and blockade
Alarm Output.

Alarm setting: 2 points in positive range, 2 points in negative range, and set arbitrarily in full scale range.
Alarm output: LED indicator, relay normally open contact closed output, capacity DC28V/2A, AC250V/2A.
Use power: 220VAC ± 10%, 50Hz ± 5%; power consumption <10W.
Use ring?: No corrosive surrounding, no strong magnetic field and other occasions.
Operating temperature: 0~50°C; Storage temperature: -20~60°C; Relative humidity: 20~90% (non-condensing).
Dimensions: width 160 x height 80 x depth 245 (mm3).
Opening size: width 152× height 76 (mm2).
The main function
Monitoring and protection of axial positions of rotary machinery such as steam turbines, turbines, compressors, blowers, etc.
Technical indicators
Input signal: Select different specifications of DWQZ series eddy current sensor system according to the required measurement range.
Linear range: Ф8mm probe 2mm;
Ф11mm probe 4mm;
Ф25mm probe 12 mm.
Displacement display ± X.XX (mm), gap voltage display -XX.XX (V), accuracy: ±1.0%.
Current output 4 ~ 20mA analog signal, load resistance ≤ 500Ω, accuracy: ± 1.0%.
Alarm output: LED flashes, relay action, relay contact capacity DC28V / 2A, AC250V / 1A.
DC-24V voltage output for powered eddy current sensors.
Failure indication: When the input signal is abnormal, LED failure indication and block alarm output.
The parameters can be displayed or set on the display by pressing a button. The parameters that can be set or displayed include: alarm value (positive alarm value, negative alarm value, positive stop value, negative stop value), alarm delay time, forward gain, negative gain , zero gap voltage, current linear correction.
With zero confirmation function, just use the instrument keys to easily make the instrument zero and mechanical zero consistent.
Automatically save historical peak value and historical alarm status after alarm, set data and history parameters can be saved for a long time after power failure.
With power-on and power-down suppression (protect historical data, suppress false alarms), self-locking alarm output function within 30 to 45 seconds after power on.
Environmental requirements:
* No corrosion, no strong magnetic field, etc.
*Use temperature: 0～50°C;
* Storage temperature: -40～60°C;
* Relative humidity: 20 to 90% (non-condensing).
Power Source: Voltage AC220V±10%, Frequency 50Hz; Power Consumption <10W.
