CJ-B08 type shaft vibration shaft displacement eddy current transformer

The CJ-B08 shaft vibration shaft displacement eddy current transducer can be widely used in the measurement and protection control of large mechanical runout (equipment vibration relative to the connecting base) in industries such as power, metallurgy, petrochemicals, steel, and environmental protection. The vibration caused by loose installation screws on the main monitoring equipment relative to the base can be detected and alarmed early, prolonging the operating life of the machine and shortening the maintenance cycle of the unit. The front-end transmitter integrates the preamplifier into the transmitter, greatly simplifying the wiring on site. The transmitter also comes with a display and on-site setting buttons, making it convenient for users to operate on site. The transmitter is powered by 24V and fully isolated internally, improving anti-interference ability. The output is controlled by a digital output of a microprocessor for analog circuits.

CJ-B08-ZD axis vibration transmitter selection: φ 8mm (8.0v/mm) sensor

CJ-B08-ZW axis displacement transmitter selects a sensor with a diameter of 8mm (8.0v/mm) or 11mm (4.0v/mm)

The column eddy current sensor is a non-contact integrated displacement measurement tool. New processes and technologies have been adopted to integrate the preamplifier into the probe, removing the intermediate wiring link and making it an integrated unit. It has the advantages of non-contact measurement, large measurement range, high sensitivity, strong resistance, not affected by oil, steam and other media, simple structure, and easy installation.

Application field

thatThe series of eddy current sensors isWidely used in various fields of industrial production and scientific research. Especially in high-speed rotating machinery (such as steam turbine units, water turbine units, fans, motors, pumps, etc.), it is widely used to measure axial displacement, radial vibration, runout, shaft speed, and phase.

At the same time, it has been widely used in fields such as metal plate thickness measurement, material identification, weighing measurement, and material deformation measurement.

Installation Instructions

1. Requirements for the tested object: The material of the tested object has an impact on the sensor characteristics, with 2mm corresponding to -2~-18V

When the measured object is a circular axis and its axis is orthogonal to the axis of the probe, it is required that the diameter of the measured object be greater than three times the diameter of the probe, otherwise the sensitivity of the sensor will decrease.

3. The thickness of the measured object affects the sensitivity of the sensor. Metal materials with good magnetic conductivity such as steel require a thickness greater than 0.1mm, while metal materials with good magnetic conductivity such as aluminum require a thickness greater than 0.6mm

4. The tested material is a magnetic sensitive metal, otherwise there may be errors.

5. The measured surface should be smooth and free of holes, scratches, etc. Speed and phase detection measurements can be taken on the measured surface mounting table or open slot. Displacement measurements generally require the surface roughness of the measured surface to not exceed 08-16um, and shaft vibration measurements generally require the surface roughness of the measured surface to not exceed 0.4-0.8um.

When placing an order, the user must specify the material, shape, size, etc. of the tested object. If the user does not specify in the contract, 45 # steel will be used as the tested material during factory calibration, and the diameter of the tested surface will be calibrated to be greater than 3 times the diameter of the probe.
