Functional Features The Proximitor Sensor features a thin design allowing mounting in either high-density DIN-rail installations or traditional panel mount configurations. Improved RFI/EMI immunity achieves European CE mark approvals without special mounting considerations. SpringLoc terminal strips require no special installation tools and facilitate faster, more robust field wiring connections. The sensor is fully interchangeable with other 3300 XL 11 mm system components.
Application Scenarios Steam turbine vibration and position monitoring, gas turbine axial position measurement, large compressor radial vibration monitoring, generator bearing position monitoring, pump shaft displacement measurement, industrial fan monitoring, heavy rotating machinery condition monitoring.
Performance Parameters The Proximitor Sensor outputs a DC voltage from -24 Vdc to 0 Vdc proportional to the gap distance. The sensitivity is 3.94 V/mm with linearity within ±0.10 mm over the 4.0 mm standard range. The frequency response extends from 0 to 10 kHz. The sensor maintains accuracy specifications across the full operating temperature range.
Material Composition The housing is constructed from nickel-plated aluminum. The connector material is gold-plated brass. The terminal strips are SpringLoc design for reliable field wiring connections.
Structural Characteristics The sensor features a compact housing suitable for panel mounting. The mounting base provides electrical isolation and eliminates the need for separate isolator plates. The housing dimensions are compatible with standard industrial control panels. The sensor includes coaxial system connectors for probe and extension cable connection.
Working Principle The Proximitor Sensor generates a high-frequency RF signal that is transmitted to the probe tip through the extension cable. The probe tip creates an electromagnetic field that induces eddy currents in the conductive target surface. The resulting energy loss is detected by the Proximitor Sensor and converted into a DC voltage output that is directly proportional to the physical gap distance between the probe tip and the target.
Installation Requirements Mount the sensor in a control panel or equipment enclosure using the panel mount configuration. Connect the probe and extension cable to the sensor coaxial connectors. Wire the sensor output to the monitoring system using the SpringLoc terminal strips. The sensor requires -17.5 Vdc to -26 Vdc power supply. Ensure the total electrical length of the probe plus extension cable equals 8.0 meters.
Usage Precautions Do not operate the sensor outside the specified temperature range. Ensure proper power supply voltage to maintain linear range performance. The sensor is not field-calibratable; factory calibration ensures accurate performance. Protect the sensor from excessive moisture and contaminants. Verify electrical length matching between all system components.
