Dual-input temperature transmitters
Moore THZ3 and TDZ3 Smart 2-wire, loop-powered HART temperature transmitters provide an isolated and linear 4-20mA output proportional to input; they accept a direct signal input from a variety of sensors and analog devices. The dual-sensor units offer backup and fail-over protection, as well as average and differential measurement. The high-select and low-select features enable the transmitter to continuously monitor 2 separate inputs and designate either the highest or lowest input as the source for the analog output or PV. The transmitters offer input-to-output analog accuracy up to +/-0.025°F utilizing sensor matching and trimming over a 100°F span.
