Extended Cable Length for Flexible Installation
The PR6423-10R-111 distinguishes itself with a 10‑meter integral coaxial cable. This extended length accommodates larger machinery where the driver unit resides farther from the measurement point. The RG178/U cable maintains signal integrity over the full distance. Fluorocarbon insulation provides excellent resistance to oil and chemicals.
Mechanical Robustness and Environmental Sealing
EPRO constructs this sensor entirely from stainless steel with full epoxy potting. Consequently, the PR6423-10R-111 survives high-pressure washdowns and temporary submersion. The M12 × 1 thread permits straightforward installation in standard drillings. Two included lock nuts secure the sensor against vibration-induced loosening.
Passive Design with Active Performance
Unlike many industrial sensors, this model contains no internal electronics. The passive eddy current coil simply reflects impedance changes to the driver. Therefore, you achieve exceptional temperature stability and long-term reliability. The EPRO CON011 converter easily conditions the signal for PLC or DCS integration.
Application Versatility in Turbomachinery
You will find the PR6423-10R-111 ideal for steam turbines, gas compressors, and hydro generators. Its 2 mm linear range captures both dynamic vibration and slow shaft displacement. Moreover, the sensor requires no calibration after installation. This feature significantly reduces commissioning time.
