Electrical parameters
Sensitivity: 7.87 volts / mm (200 mV/mil) ±12.5%/20%, including interchangeability errors when measured in 0.25 mm (10 mil) increments over a linear range of 1.5 mm (60 mil).
Output Signal: Outputs a linear voltage signal proportional to the change in the surface gap of the object under test, starting at approximately 0.25 mm (10 mils) from the target surface and from 0.25 to 1.75 mm (10 to 70 mils) (approximately - 1 to - 13Vdc).
Frequency response: 0 to 10kHz, 0,-3dB typical, field wiring length 305 m (1000 ft).
Mechanical & Installation Parameters
Thread size: 1/4 - 28 UNF thread, non-armoured.
Counterbore requirements: Minimum diameter of 9.5 mm (0.375 in.), minimum diameter of 13 mm (0.5 in.) recommended. Counterbores smaller than 13 mm (0.5 in) often cause a change in the scale factor of the distant clearance.
Target Requirements: Minimum diameter of 8.9 mm (0.35 in.) for flat targets; For axial measurements, the minimum shaft diameter (X-Y azimuth probe configuration) is 30 mm (1.2 in.) and the minimum axial diameter (X-Y proximity probe axial offset of 23 mm (0.9 in)) is 20 mm (0.8 in.).
Environmental parameters
Operating temperature range: Usually the probe and extension cable can work in the environment of -34°C~177°C, and the preamplifier can work in the environment of -34°C~66°C, but the specific model may be slightly different.
Protection level: not clearly given, but usually has good protection performance, can adapt to dust, moisture and other conditions in industrial environments.
