APAQ-LR is a multirange 2-wire DIN rail mountable adjustable temperature transmitter for Pt100 RTD input or 5 different thermocouple types.
APAQ-LR and APAQ-LC are analog, 2-wire, DIN rail transmitters with selectable ranges for Pt100 and selectable types and ranges for thermocouple input. The compact housing snaps onto a 35 mm DIN rail and is equipped with rugged terminals for easy and safe wire connections. The selection of measuring ranges and thermocouple types is made with internal solder pads. The fine adjustment is made with potentiometers in the front.
APAQ-LR is adjustable for different Pt100 ranges and has a temperature linear 4-20 mA output.
APAQ-LC covers 5 different thermocouple types, is continuously adjustable and has a voltage linear 4-20 mA output.
