Operating Conditions

Measurement Range: The EPRO PR6423/10R-010 may have a static measurement range of ±1.0 mm (0.04 in) and a dynamic range of 0 to 500 microns (0 to 20 mils). Some models may have a measurement range of 0 to 5 mm.

Initial Air Gap: The initial air gap is 0.5 mm (0.02 in) or 1 mm (40 mils), depending on the specific model.

ISF: The sensor typically has an ISF of 8 v/mm (203.2 mv/mil) ± 5 % over the temperature range of 0 to 45 °C.

DSL: The DSL is ±0.025 mm (±1 mil) over the temperature range of 0 to 45 °C.

Minimum shaft diameter: Typical diameters of measuring shafts are no less than 25 mm (0.98 in), or no less than 50 mm (1.97 in), depending on the model.

Target material: Target material is ferromagnetic steel, such as 42CrMo4 (AISI/SAE 4140).

Operating temperature range: The sensors have a wide operating temperature range of -35 °C to +200 °C (-31 °F to +392 °F), although some models have an even longer operating range of -40 °C to +180 °C (-40 °F to +356 °F); for other models, the cable has an operating temperature range of -40 °C to +150 °C (-40 °F to +302 °F).

Protection rating: IP66 or IP67, providing excellent standards of protection against dust and water.

Output signals: 4-20 mA, 0-10V DC and RS-485 can be easily integrated with other control systems.

Power supply: The power supply is typically 24 VDC.

Product features

Non-contact measurement: The eddy current working principle prevents the measuring element from physically contacting the target; therefore, in a sense, the wear of the sensor and the measured object is reduced and the impact of the measurement on the operation of the monitored equipment is minimized.

Accurate measurement of various parameters: The EPRO PR6423/10R-010 is able to accurately measure radial and axial dynamic displacement, position, eccentricity and speed, providing complete details on the mechanical condition of the machine. Therefore, potential problems can be detected at an early stage, avoiding unnecessary failures and maintenance costs.

High reliability and accuracy: The high-precision measurement and stable performance of the EPRO PR6423/10R-010 make the measurement data highly accurate and reliable, even in harsh industrial environments. The rugged construction combined with international standards, CE, ATEX, CSA compliance also increases the reliability and suitability of the device in hazardous areas.

Easy integration: Sensors using standard output signals and protocols are compatible with any control system; they are easily integrated into existing factory automation architectures, connected to DCS, PLC or other control systems for real-time monitoring and control of the system.

Applications

The EPRO PR6423/10R-010 can be used to monitor critical turbomachinery of one form or another in various industrial sectors. This includes steam/gas/hydraulic turbines, compressors, gearboxes, pumps and fans. Continuous monitoring of the dynamic displacement, position, eccentricity and speed of the shaft ensures that such critical equipment continues to operate safely and reliably, thereby improving production efficiency and reducing maintenance costs.
