Description: These tiny potentiometer transmitters measure just 52 × 22 × 18 mm. They provide a 2.5 V excitation to your potentiometer and the output of the potentiometer is then converted to a 4 to 20 mA signal.
Span and zero adjustment trimpots can be accessed under rubber plugs on the conditioner's body.
