A Vishay thermistor from our Partner Library, with resistance that is sensitive to temperature, is used in a Wheatstone Bridge configuration. It produces a differential voltage that is amplified by an op-amp circuit. The op-amp output voltage is approximately proportional to temperature.</p><p>The rest of the control loop is modeled here using ideal mathematical control blocks. This abstraction allows the designer to focus on the overall performance of the regulator, and to assess the choice of PID gains during actual transient operation.</p><p>All of the parameters in blue can be changed by the user and a new simulation run. The updated scope waveform results will show the effect of that change. You can change the electrical resistance of the "laser", which is just a simple resistance heating element for this example, to change the power dissipation level. You can also change the heat transfer resistance values in the thermal network, to see their effect on system performance. Finally, you can change the PID control block gains and see the effect on the steady-state and transient behavior of this temperature regulation system.</p><p>Note: You can move the waveform probes to see any other signal in the system.</p> About text formats Tags TECPeltierThermistorPIDVIshay NTC thermistor Select a tag from the list or create your own.Drag to re-order taxonomy terms.

The sensor element (now positive temperature coefficient) has been switched in the opposite arm of the wheatstone bridge. In this live tunable design , the target temperature level of the laser device can be chosen between 5 and 30°C. The temprature regulation will be working accordingly. The tolerances of the TFPT sensor (R25 in % and slope ppm/k) can be chosen inside the specification (+/-0.5% and +/-400 ppm/K)</p> About text formats Tags TECPeltierPIDVISHAYRTDTFPT Select a tag from the list or create your own.Drag to re-order taxonomy terms.
