TT820D
Digital Thermocouple Transmitter

TT820D

Description
The TT820D is a digital transmitter that converts the signal from a thermocouple to a linearized 4-20 mA output. 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 a two points calibration, a re-scaling, iltering options and identification of the transmitter.
