YD9810 Axis vibration transducer

YD9810 Axis vibration transducer

Axis vibration transducer directly connect with DCS, PLC interface provides a simple, low-cost way to monitor rotating machinery rotor vibration and transmitter vibration.

● Connection Diagram is as follows:



Under what circumstances should recalibrate the transmitter?

Ø  Transmitter will not be used for more than one year;

Ø  Transmitter used continuously for two years;

Ø  Tested material and factory calibration material discrepancies;

Ø  After troubleshooting.

Calibration devices and equipment

Ø  Displacement calibrator

Ø  Micrometer

Ø   Digital Multimeter

Ø  +24V DC power supply

Ø  Sine wave signal generator


Displacement characteristic curve calibration

Select the same material tested specimens.

Installed probe micrometer (range should be larger than the sensor range 20%).

Respectively, power, digital multimeter probe to the transmitter.

Rotary displacement calibrator knob so that the specimen plane close to the probe, the probe head and then transferred to the sensor and sample spacing linear starting distance.


Check transmitter output

Turn on the power, rotational displacement calibrator knob, adjust the probe is linear midpoint, see OUT output whether 4.00mA ± 1%; sensor fixed on the vibration table, select the appropriate midpoint of the vibration frequency and vibration amplitude, view the output OUT whether 12mA ± 1%; selecting the appropriate end of the vibration amplitude and the vibration frequency, to see if the output OUT is 20mA ± 1%; does not meet the above needs to be sent if the factory calibration;


Fault repair

Sensor system anomalies appear in the calibration or work, first on their own preliminary examination, the problem is serious, please contact the Company or the Company throughout the sales and service agents.

● System Check

1) Terminals wiring is wrong;

2) Wiring short or open;

3) Power supply voltage is correct;

4) Measuring instruments are shorted or open.


●Probe Check

1) High frequency probe and probe head plugs are clean, if dirty, please use ethanol scrub.

2) Extension cable (extension cable if there is any) whether short or open circuit, if the fault, replace the extension cable.

3) Check whether the probe shorted or open: first extension cable disconnected (if any), and then a multimeter to measure the resistance of high frequency probe pin plug and the plug housing between digital, its normal value should be in the 2.0 to 10.0 between Ω, if the resistance value is very small (less than 1.0Ω), the description of this probe short-circuit; If the measured resistance value is very large (greater than 10Ω), a description of this probe is open or poor contact. When found in both cases, you have to replace the probe.

● Check the transmitter

1) To check whether the probe and extension cable supporting the transmitter. If there is an extension cable, be sure to connect the extension cable.

2) The determination of the intact probe, connected to the transmitter. When the probe head against the metal conductor, the original signal output of the transmitter should be minimized; When the probe head away from metal conductors, the original signal output of the transmitter should be maximized. Otherwise it can be determined that this transmitter has been damaged, or the sensor system is bad, then the system should be repaired or replaced transmitter.
