TT820D Thermocouple Temperature Transmitter

Brand: Intempco Controls, Inc.

The TT820D is a low cost microprocessor-based 2-wire DIN rail-mounting transmitter.

The TT820D features a one point calibration adjustment with two push buttons as well as an advanced software programming via the RS-232 input.

The advanced programming allows two points calibration, re-scaling, filtering options and identification of the transmitter.

TT820D is designed for highest reliability and excellent industrial performance. Automatic cold junction compensation and a low-drift input amplifier maintain accuracy under varying ambient conditions.
