Minimal Calibration with Long Term Stability       0.025%/Year

The T798 is a Highway Addressable Remote Transducer (HART) based temperature transmitter that can be factory or field configured using an optional 1 or 2 line alpha-numeric display, optional PC based software and cable. Alternatively an HC275 Hand Held Communicator loaded with the T798 Device Description from the Hart Foundation Library can be used.

The T797 is a programmable temperature transmitter that can be factory or field configured using the same optional 1 or 2 line alphanumeric display as the T798.

Both the T798 and T797 accept a wide variety of thermocouples (B, C, E, J, K, L, N, R, S, T, U & special) and 2-wire, 3-wire, or 4-wire Platinum RTDs (DIN alpha = 0.00385, SAMA alpha = 0.003923 and special) as well as millivolt (mV) and resistance inputs. They provide an isolated 4- 20mA output loop that is proportional and linear to the desired temperature input range. The factory can configure custom curves and accommodate other input types including 10 Ohm Copper and 120 Ohm Nickel RTDs.
