TX12

TX12 is a smart loop-powered RTD in-head temperature transmitter connects to any standard Pt100 resistance sensor and converts the linearized temperature to a 4 to 20mA signal. The transmitter is a two wire device and is fully configurable by the user, over a wide temperature range, with the aid of a simple pushbutton. This new TX12 design incorporates additional configuration menus, allowing the user to push button trim the transmitter output at both zero and span, ideal for trimming out sensor errors. The transmitter advanced circuitry guaranties high stability over the wide operating ambient temperature ranges experienced by head mounted devices. It s features is the program LED, which provides visual indication of sensor fault when in normal operation and is also used to guide the operator through the simple menus during configuration.
