Product Introduction
The Epro PR6480/361-000 Eddy Current Sensor is a precision-engineered non-contact vibration and displacement measurement probe designed for use in high-performance rotating machinery monitoring systems. Belonging to the Epro PR6480 series, this sensor is specifically developed for applications that demand high accuracy, wide temperature tolerance, and reliable operation under harsh industrial conditions.
The PR6480/361-000 works on the eddy current principle, where an electromagnetic field generated at the sensor tip interacts with a conductive target. Variations in the target’s position or vibration alter the field, allowing the sensor to produce a proportional voltage output that corresponds to the displacement or vibration amplitude. When paired with Epro converter units such as CON011, CON021, or CON031, the PR6480/361-000 delivers highly linear and temperature-stable measurement signals.
Engineered for industrial durability, this model features stainless-steel housing, IP67-rated environmental protection, and excellent resistance to oil, dust, and EMI noise. It is ideal for long-term installation in power generation, petrochemical, and process industry environments where precise shaft vibration and clearance monitoring are critical for operational safety.
