Product Details

Integrated vibration probe HZDB4

The integrated vibration probe HZD-B-4 integrates the vibration velocity sensor and precision measurement circuit together to form a high-precision vibration measurement system, realizing the function of the traditional "sensor+monitoring instrument mode vibration measurement system. The transmitter can be directly connected to DCS, PLC or other equipment, making it an ideal choice for vibration measurement of factory equipment such as fans, motors, water pumps, etc.

Is there any poor contact phenomenon in the capacitive transmitter

1. Connectpower supplyCheck the output voltagesignalThe state. If there is no output voltage, check whether the power supply voltage is normal first; whether it complies withpower supplyrequirement; Is there any wiring error between the power supply and the load device. ifterminal blockNo voltage or reverse polarity can cause no voltage signal output. If the above reasons are excluded, further examination should be conductedamplifierIs there any damage to the components in the board circuit; Whether there is poor contact in the circuit board connectors can be determined by comparing the measured voltage of the normal instrument with the corresponding measured voltage of the faulty instrument. If necessary, the faulty amplifier board can be replaced. When checking the flow type, for J typecapacitanceSpecial attention should be paid to taking anti-static measures for the amplifier board.

2. Connect the power supply, and if the output is too high (greater than 10V) after receiving the input pressure signalDC）Or the output is too low (less than 2.0VDC), and there is no response when changing the input pressure signal and adjusting the zero and range screws. For such faults, in addition to checking for any abnormalities in the sensitive components of the measuring part, the "oscillation" on the amplifier board should also be checkedcontrol circuitWhether the 'part' is working properly or not. The normal peak voltage between high-frequency transformers T1-12 should be 25~35VP-P; The frequency is approximately 32kHz. Next, check each component on the amplifier boardoperational amplifierThe working condition; each partcomponentsWhether there are any damage issues, etc. This type of malfunction requires replacement of the amplifier board.

3. The requirements for circuit design and process assembly quality are very strict. In actual use, for any circuit faults that occur, after inspection and confirmation, it is necessary to contact the manufacturer to replace the faulty circuit board to ensure the stability and reliability of the instrument's long-term operation. When using a capacitive level gauge, if it is not a metal container, it is necessary totransmitterUse a wire to connect the outer shell to the bottom of the container, otherwise the measurement will be inaccurate.
