EPRO PR9268/301-000

Operating Parameters

Power supply: EPRO PR9268/301-000 usually uses 24 V DC power supply, which is generally considered to be stable and reliable. This voltage level is widely used in industrial working environments; therefore, it is easy to integrate with existing power supply systems.

Wide temperature range: The different types housed in EPRO PR9268 represent different models that can operate in a wide temperature range of -20 to +100 °C (-4 to +212 °F), such as PR9268/01x-x00, PR9268/20x-x00 and PR9268/30x-x00, and the remaining PR9268/60x-000 and PR9268/70x-000 can operate in the range of -20 to +200 °C (-4 to +392 °F). The extended temperature range is very wide, so the sensor can be used in different low-temperature storage facilities and high-temperature processing plants.

Protection rating: The protection rating of the EPRO PR9268 varies depending on the model. The PR9268/20x-x00 and PR9268/30x-x00 are rated IP55, while the PR9268/01x-x00 and PR9268/60x-000 and PR9268/70x-000 are rated IP65. These ratings protect the sensor from dust and water intrusion; therefore, it is reliable and durable when working in a variety of conditions.

Measuring range and accuracy: The measuring range and its accuracy vary from model to model. For example, the +/-2 kilomicron PR9268/302-100 can measure speeds between 0 and 60,000 revolutions per minute, but with an accuracy of ±0.1%. This is different from the PR9268/201-000, which has a measurement range of +/-1,500 µm (59,055 µin), a sensitivity of 28.5 mv/mm/s (723.9 mv/in/s) (80 hz/20 °C/100 kohm), and an accuracy of +/-1% of full scale.

Bandwidth: Some models also offer good bandwidth for some high extended ranges; for example, 10 kHz for the PR9268/206-100 enables such measurement configurations to control fast changes in the measurement parameters, suitable for dynamic applications.

Product Features

Speed and Vibration: The main function of the EPRO PR9268/301-000 is basically monotonic monitoring of speed and vibration of rotating or reciprocating machinery. It can send alarm signals to different machinery when the mechanical vibration amplitude is large. These signals are converted into voltage signals proportional to the vibration speed, so they are easily combined with different control systems and monitoring equipment for real-time speed monitoring and analysis of data therein.

Non-contact measurement: In addition, the concept of some models in the EPRO PR9268, such as the PR9268/300-000, uses non-contact measurement technology based on the principle of electromagnetic induction. This will completely exclude target wear and ensure that maintenance is postponed to the future, extending the service life of the sensor and the measuring device.

Directional measurement: Some models, such as the PR9268/201-000, are manufactured in a way that they are aligned for certain directions. Whether placed vertically or horizontally, this provides different sensitivities and characteristics, allowing accurate measurement of casing vibrations in different directions in critical turbomachinery applications.

Compatibility and integration: The EPRO PR9268/301-000 is designed to be compatible with a range of control systems and monitoring equipment. It can provide output signals that may vary as 4-20 mA DC output, analog voltage, frequency or pulse for easy integration into existing industrial automation systems.

Application range

The EPRO PR9268/301-000 has a wide range of applications in many industrial fields. It is most widely used in turbomachinery, including steam, gas and hydro turbines, where accurate shaft vibration and speed measurement is critical to ensure safe and efficient operation of the equipment. It is also used in compressors, pumps and fans to monitor machinery condition and avoid impending failure. The sensor can also be used in many industrial machinery gearboxes, camshafts and crankshafts to provide useful data for condition monitoring and predictive maintenance.
