The PT1MA adds 4...20 mA position feedback signal to Celesco’s compact line of cable-extension transducers. The
PT1MA is available with full stroke ranges from as little as 2
inches on up to 50 inches with adjustable zero and span settings to precisely match the full scale output to your exact
measurement range.
The PT1MA offers several options including forward and reverse 0...20 and 4...20 mA output signals, alternate measuring cable exits and a couple different electrical connection
options.

The output signal direction can
be reversed at any time by
simply changing the dip-switch
settings found on the internal
signal board. After the settings
have been changed, adjustment of the Zero and Span
trimpots will be required to
precisely match signal values to
the beginning and end points
of the stroke.
