Performance Parameters The Proximitor provides identical electrical performance to other 3300 XL 8mm Proximitors. The linear output range is 2.0 mm (80 mils) with linearity of ±0.025 mm (±1.0 mil). The incremental scale factor is 7.87 V/mm (200 mV/mil) with ±0.25 V/mm tolerance. The average scale factor is within ±1.0%. The frequency response is 0 to 10 kHz (-3dB). The CSA/NRTL/C certification ensures safe operation in specified hazardous environments without compromising measurement performance.

Material Composition The Proximitor enclosure is constructed from aluminum with anodized finish. The panel mount base is made from electrically insulating composite material certified for hazardous location use. Internal electronic components include precision operational amplifiers, RF demodulation circuits, and filtering networks. The PCB is FR-4 epoxy glass fiber with industrial-grade components. Connectors are gold-plated brass. The unit is fully encapsulated with materials rated for the specified temperature range.

Structural Characteristics The Proximitor features a rectangular enclosure with standard 8mm diameter mounting holes on the panel mount base for screw attachment. The RF input connector and signal output connector are located on opposite ends. The enclosure includes grounding provisions for hazardous location installation. Internal layout separates RF and signal processing stages. The unit is fully potted for environmental and vibration protection. CSA/NRTL/C approval labels are affixed to the enclosure.

Working Principle The working principle is identical to other 3300 XL 8mm Proximitors. The unit receives the modulated RF signal from the probe via extension cable, demodulates it using precision detector circuitry, filters and amplifies the resulting signal, and produces a DC voltage output proportional to the probe-to-target gap. The output is -10.0 VDC at the recommended 0.25mm (10 mils) mounting gap. The CSA/NRTL/C certification ensures that all electrical energy levels are limited to safe values for the specified hazardous environment.

Installation Requirements

• Must be installed in accordance with CSA/NRTL/C Class I, Division 2 wiring methods and practices
• Mount on a grounded metal panel in a suitable enclosure rated for the hazardous location
• Ensure proper electrical isolation from ground using the insulating panel mount base
• Use sealed conduit or cable glands for all cable entries into the hazardous area enclosure
• Connect the probe/extension cable to the RF input connector with proper torque
• Connect output to the monitoring system using shielded cable with shield grounded at the safe area end
• Connect -24 VDC power supply observing correct polarity
• Install external barrier or isolator if required by local electrical codes for intrinsically safe circuits
• Maintain all hazardous location certification labels and markings
• Follow all applicable national electrical codes for Division 2 installations

Usage Precautions

• The CSA/NRTL/C certification is valid only when the unit is installed according to approved methods
• Do not modify or repair the unit; modifications void the hazardous location certification
• Ensure all conduit seals and cable glands maintain the integrity of the hazardous area enclosure
• Never apply power without the probe connected
• Do not exceed the supply voltage range
• Ensure target material matches calibration material
• Keep probe cables away from high-voltage power cables
• Do not kink or sharply bend probe cables
• Check connector tightness periodically
• Replace unit if output drifts beyond ±10% of calibrated value
• Store in original packaging if not installed immediately
• Follow lockout/tagout procedures for maintenance in hazardous areas
