Altek Model 11 Resistance Temperature Detector (RTD) Simulators provide 11 precise temperatures for inputs to transmitters, recorders, controllers, alarms, data acquisition and computer systems. The Model 11 allows 2, 3 or 4 wire connections. Factory calibration includes compensation for the resistance of the builtin lead wires. Conformity to the particular RTD curve is in accordance with the latest standards for exact temperature simulation.

Simulate temperature into any instument that measures a Pt 100 ohm RTD based on the worldwide DIN/IEC 751 standard curve with an alpha of 1.3850 (sometimes displayed as 0.00385 or 385). Resolution is 25, 50 or 100 degrees, corresponding to full scale output of 250, 500 and 1000 degrees respectively. Positive switch selection allows quick, easy settings for any output. Calibrated accuracy is ±0.1°C. The low cost Model 11 is a complete compact simulator for checkout and calibration of all RTD instruments in the field, shop or control room.
