REEL SENSOR APPLICATION NOTES

The reel sensor is comprised of two basic parts: 1. Linear to rotary unit 
2. Transducer or encoder unitOther units are also available such as the film potentiometer unit with 4-20ma output.

Resolver
The resolver transducer unit is used whenever absolute measurement is required. The resolver digital output representing the actual position is retained through power up/down cycles. The resolver must be geared appropriately so that it turns 1 revolution or less over the entire linear range of the cable travel. For example, a linear range of 100 in.:
 
100in10 in/rev = 10 revolutions 

Gear ratio for the resolver package is 10:1
Resolution: single resolver = 4096
                 dual resolver = 262,144

Scale above numbers and read out: 
                     100.0 in. or 100.000 in.

Pulse Encoder
The incremental pulse encoder can be used effectively when retained readings are not necessary between power up/down cycles.

For example, linear range of 100 in.:
 
100in10 in/rev = 10 revolutions 

Select encoder with 1000 pulses/rev 
Counter output for full range travel:

                    10 rev x 1000 pulses/rev = 10,000 pulses

Scale and read out: 
                    100.00 in.
