The EPRO PR6423 is a high - performance eddy - current sensor widely used in industrial automation and monitoring systems. Here is the detailed information in English:
- Brand: EPRO
- Model: PR6423
- Country of Origin: Germany
- Measuring Range: Static ±1.0 mm; Dynamic 0 - 500 μm (peak - to - peak)
- Sensitivity: 8 V/mm
- Measuring Material: Conductive steel (such as 42CrMo4)
- Nominal Air Gap: 1.5 mm (center of the measuring range)
- Linearity Error: ≤±1%
- Zero - point Temperature Difference: 200 mV/100K; Sensitivity Temperature Difference: 2%/100K
- Long - term Drift: ≤0.3%
- Operating Temperature: - 40°C to + 70°C (some models support short - term temperature resistance of + 120°C or + 200°C)
- Power Supply Voltage Influence: ≤20 mV/V
- Cable Length: Standard 1 meter, can be extended to 3 meters or 9 meters (depending on the model)
- Protection Level: IP65/IP67
- Output Signal: 4 - 20 mA or ±5 V analog signal
- Non - contact Measurement: The PR6423 adopts a non - contact measurement method, which does not touch the measured object, avoiding interference with the operation of the equipment and wear on the sensor itself.
- High Precision: It has high - precision measurement performance, with a linearity error of ≤±1% and a long - term drift of ≤0.3%, which can accurately measure the vibration and displacement of the shaft.
- Good Environmental Adaptability: It can work in a wide temperature range from - 40°C to + 70°C, and some models can withstand short - term high temperatures. At the same time, its protection level reaches IP65/IP67, which can adapt to harsh industrial environments.
- Compact and Durable Design: The sensor has a compact structure, small size, and light weight, which is convenient for installation and use. At the same time, it is made of high - quality materials, with high reliability and durability.
- Vibration and Displacement Monitoring: It is mainly used to monitor the shaft vibration, axial displacement, eccentricity and other parameters of rotating machinery, such as turbines, compressors, pumps, fans, etc. By accurately measuring these parameters, it can provide important data support for the condition monitoring and fault diagnosis of equipment.
- Signal Conversion and Transmission: The sensor can convert the measured physical quantity into an electrical signal (4 - 20 mA or ±5 V analog signal) and transmit it to the subsequent monitoring and control system for further processing and analysis.
- Turbine Machinery: It is widely used in steam turbines, gas turbines, hydro - turbines, etc., to monitor the vibration and displacement of the turbine shaft, ensuring the safe and stable operation of the turbine.
- Rotating Equipment: Such as sleeve - bearing motors, gearboxes, water pumps, etc. It is especially suitable for scenarios where the casing vibration monitoring fails due to oil - film damping, and can directly monitor the dynamic behavior of the shaft system.
- Industrial and Laboratory: It is widely used in the equipment health monitoring of industries such as power generation, petrochemical, chemical, and metallurgy, as well as in some laboratory equipment that requires high - precision vibration and displacement measurement.
