- Robust Construction: Designed for the heaviest industrial applications requiring superior mechanical strength.
Application Scenarios
Perfectly suited for the largest turbines, heavy-duty compressors, and industrial fans where shaft displacements are extremely significant and a maximum linear range is required to prevent signal saturation.
Performance Parameters
- Linear Measurement Range: 200 mils (5.0 mm)
- Frequency Response: 0 to 10 kHz (-3 dB)
- Operating Temperature Range: -52°C to +177°C (-62°F to +350°F)
- Supply Voltage: -24 VDC nominal
Material Composition
Constructed with premium 316L stainless steel and high-temperature dielectric materials, ensuring structural integrity and electrical isolation in the most demanding environments.
Structural Characteristics
Features a streamlined profile with an integrated cable exit that minimizes bending stress. The M30 thread provides secure mounting in heavy machinery housings.
Working Principle
Operates on the principle of electromagnetic induction. The probe acts as one plate of a transformer, with the conductive shaft acting as a shorted secondary. Changes in gap alter the coupling coefficient, changing the coil’s impedance.
Installation Requirements
Install in a properly sized M30 tapped hole. Ensure adequate clearance around the probe body to prevent electrical arcing to grounded surfaces. Verify that the total system length matches the proximitor’s calibration specification.
Usage Precautions
Inspect the probe tip for scratches or pitting before installation, as surface damage can cause signal non-linearity. Keep the cable away from sharp edges and hot exhaust pipes.
