Functional Features The Proximitor Sensor features improved RFI/EMI immunity that satisfies European CE mark approvals without requiring special shielded conduit or metallic housings. SpringLoc terminal strips require no special installation tools. The multiple agency approval option ensures compliance with international safety standards. The sensor is fully interchangeable with other 3300 XL 11 mm system components.
Application Scenarios Power plant steam turbine monitoring in hazardous areas, chemical processing equipment vibration monitoring, oil and gas compressor monitoring requiring agency approvals, petrochemical refinery rotating equipment monitoring, offshore platform machinery protection systems, nuclear power plant condition monitoring, regulated industrial environments worldwide.
Performance Parameters The Proximitor Sensor outputs a DC voltage proportional to the gap distance with 3.94 V/mm sensitivity. The linear measurement range is 4.0 mm with deviation from best fit straight line less than ±0.10 mm. The frequency response is 0 to 10 kHz typical. The multiple agency approvals cover intrinsically safe and non-incendive installations.
Material Composition The housing is constructed from nickel-plated aluminum. The connector material is gold-plated brass. The terminal strips feature SpringLoc design.
Structural Characteristics The sensor features a compact housing for panel mounting. The mounting base provides electrical isolation. The housing is rated for industrial environments with resistance to oil, moisture, and contaminants. The sensor includes coaxial system connectors.
Working Principle The Proximitor Sensor generates a high-frequency RF signal transmitted to the probe tip. Eddy currents induced in the conductive target surface cause an impedance change detected by the sensor. The sensor converts this into a DC voltage output directly proportional to the physical gap distance.
