For nearly a quarter century the Model TL transmitter has been diligently monitoring and controlling temperature in processes where accuracy, stability, and repeatability are of paramount importance to product quality, efficiency and/or safety. Calibration of the device is easily accomplished through highly sensitive non-interactive zero and span potentiometers. Large rugged terminals insure easy and secure wire connection. Although current transmitter technology has transcended this design, the model TL has proven to be a workhorse in thousands of processes across all industries and continues to be specified for new as well as replacement applications.

With .05% of span accuracy linearized with temperature, the Model TL transmitter delivers high accuracy and precise adjustability. The trim potentiometers are designed for high stability and ease of adjustment for applications where accuracy is an imperative.

The transmitter may be installed in a connection head or mounted separately from the sensor in a panel on snap-track or on a DIN rail (optional adaptor TT02).
