Tap Position Transmitter
For accurate remote indication of tap position selection on a high voltage
transformer. The variable tap position voltage is monitored, a D.C. output produced
which is proportional to the tap position.

Slide Wire Transmitter
Designed for accurate measurements and transmission of resistance ratio of a 3 wire
potentiometer. A stabilised voltage is applied to the potentiometer and the voltage
measured from the zero to the end of the wiper. This is amplified and the D.C. output
produced is proportional to the resistance value.
Specification
Input Span: Minimum 1kΩMax 50kΩSpecify values of R1, R2, R3
Example for 1k Potentiometer: R1 = 1k, R2 = 0, R3 = 1k
Example for 5k Potentiometer using only 4k;
R1 = 5k, R2 = 1k, R3 = 4k (Remember R1 = R2 + R3)
Outputs: 0/1mA, 0/5mA, 0/10mA, 0/20mA or 4-20mA,
0/1, 0/5, 0/10V D.C.
Auxiliary Power: A.C. 110, 120, 220, 240, 380, 415V,
63.5, 139, 208, 277, 440, 480V
D.C. 12, 24, 48, 110, 120 or 135V
Note:
Not all applications provide for the slider to mechanically travel the full distance
along the resistor track. Normally the first resistor step is inside the transducer and
its value should be stated when ordering, as well as the total track resistance. End of
track or connecting lead resistance, if significant, should also be considered. For
satisfactory operation, the change in resistance should be greater than 20% of the
total resistance.
