EPRO PR6423/010-010 + CON021 Shaft Vibration Sensor Kit

The EPRO PR6423/010-010 + CON021, also cataloged as the PR6423/010-010 + CON021 Shaft Vibration Sensor Kit, operates as a dedicated hardware component for non-contact shaft displacement measurement and signal conditioning within MMS6000 machinery protection systems.

Hardware Specifications

Eddy-Current Probe Scaling & Gap Voltage Validation

The PR6423 probe head generates a high-frequency electromagnetic field that senses distance variations to conductive target shafts. Combined with the CON021 signal converter, the system executes accurate eddy-current probe scaling, delivering an 8 V/mm output sensitivity across static and dynamic measurement ranges. Technicians perform gap voltage validation during installation to set the probe tip within its 1.5 mm nominal linear gap window. The CON021 module converts high-frequency impedance fluctuations into standardized analog signals, enabling direct transmission of shaft position and radial vibration data to downstream PLC and DCS architectures without distortion.

Frequently Asked Questions

Q: How does the CON021 converter interface with field wiring and central control panels?

A: The CON021 converter mounts directly onto a standard DIN rail inside field junction boxes or control panels, accepting sensor cable inputs and delivering linearized analog outputs via integrated screw terminals powered by an external 24 VDC source.

Q: Can the PR6423/010-010 probe operate inside high-temperature machinery housings?

A: Yes. The passive stainless steel probe tip and 10-meter continuous cable withstand severe environmental thermal exposure ranging from -35 to +180 deg C, while the CON021 signal converter must remain in a milder cabinet environment between 0 and +65 deg C.

Field Installation Guidelines

Mount the PR6423/010-010 probe into its mechanical bracket and adjust the tip spacing using a feeler gauge to match the 1.5 mm nominal gap distance, or monitor DC gap voltage output at the CON021 terminals until achieving target bias. Secure the CON021 converter onto a standard 35 mm DIN rail in a protective panel.

Connect probe cabling directly to the converter screw terminals, taking care not to exceed minimum bend radius limits along the 10-meter cable run. Route all field signal wires through grounded metallic conduit, keeping them separate from high-voltage motor power lines by at least 300 mm. Ground signal cable shielding at a single point on the main cabinet earth bar to prevent common-mode ground loop noise.
