Note: “_xx.x” indicates that the left-most display character (for higher resolution) is not available at the
scale factor selected due to limitations of the meter. The meter has a minimum input requirement of 200
microvolts per count.
•
The first digit in the sensor number indicates the specified linear measuring range in millimeters. (The
conversion factor from inches to millimeters is .03937.)
•
The letters “S” and “U” indicate whether the sensors are shielded or unshielded.
•
Other sensors, including differentially operating ones are available. If your application requires one of these
sensors, a special supplement to this manual will be made available.
Measuring
The specified linear measuring range for an inductive system is directly proportional to
Range the diameter of that sensor. Changes in oscillator frequency or power to the sensor normally have
no effect on measuring range. For any given sensor diameter, unshielded sensors have a greater
measuring range than shielded sensors. This is because the sensor’s field will “couple” with the
shield, in effect limiting the amount of field available for interacting with the target.
TARGET =
2.5 to 3X diameter of
an unshielded sensor
UNSHIELDED SENSOR
SHIELDED SENSOR
TARGET =
1.5 to 2X diameter of
an shielded sensor
