R/T82000 PRODUCT OVERVIEW

This high quality analogue transmitter is easy to scale via a simple solder link on the top of the transmitter and can even be re-scaled in the field. Fine zero and span adjustments is done using independent precision potentiometers. The electronics are completely sealed in a rugged epoxy-coated metal housing.

Easy-To-Scale via a simple solder link on top of the transmitter. Can even be re-scaled in the field. Fine ZERO and SPAN adjustments using independent

precision potentiometers. Electronics are completely sealed in rugged epoxy-coated metal housing. RTD (Pt100) units are completely linearized and thermocouple units are voltage linear. Off-the-Shelf availability for RTD (Pt100) and thermocouples type K and J. Other Thermocouple inputs and Intrinsically safe versions are available. Ask for our POTENTIOMETER transmitter.
