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.

The measured resistance quantity"rntc" or "rpts" or "rtfpt" of the "therm1" entity can be compared to the R-T curve of the data sheet.</p> About text formats Tags VISHAYNTCThermistorRTDPTSTFPT Select a tag from the list or create your own.Drag to re-order taxonomy terms.
