SPECIFICATION & PROBE NOTES

Dimensions:
All dimensions are shown as typical only. Please contact the factory for exact dimensions.

Maximum Range: Same as the diameter of the sensor element. (Minimum range is touch or 0.1% of full scale.)

LINEAR Range: Two thirds (0.67) times the sensor diameter typical.

Probe Interchangeability: ±10% of full scale maximum change, ±2% typical.

Probe Material Composition: A and E, stainless 303: V, Inconel 600, other materials available.

Calibrations: There are 21 numbered, standard calibrations available, please consult factory and specify when ordering.

Range:
•Standard listed ranges are ratios from 0 to10.000VDC analog output, but each probe may be calibrated with several range versus sensitivity calibrations. Calibration sensitivity from 0.001VDC/0.001" (0.0254mm) to 10.000VDC/0.001”(0.0254mm) are available.
•Range is defined as from touch to full scale reading, ±50% of range = ±10.000VDC calibration optional.

Grounding: “-D” dip coatings are available to prevent the electronically driven sensor/guard elements from being accidentally earth grounded and shorted.

Extension Cables: Many extension cables are available depending upon connector types. Consult factory for proper part numbers. Example: EC-D-L2-5 is a standard 5 foot extension cable with female BNC to male BNC connectors.
