TT820D Thermocouple Temperature Transmitter
Brand: Intempco Controls, IncThe 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.
