2,2A Temp Controller in Mini Instrument format with LED temperature display WTC3293-14001 The WTC3293-14001 is a mini-instrument temperature controller with a temperature (not resistance) display and onboard a
Let’s look at the other end of the chart; the curves above 50℃. There is little change in resistance but large changes in temperature in this section. The curve is relatively flat. That means it is easy to get inaccurate temperature readings because the resulting resistance changes are so...
Figure 4. PTC Top View SET THE SENSOR BIAS CURRENT Choosing the right thermistor resistance range and bias current is important to optimize performance of your temperature control system. Table 4 shows the resistance at 25°C of six thermistors that are available from Wavelength Electronics. ...
With such a scheme, any heat generated at the PTC thermistor element hardly escapes to the outside. Accordingly, it becomes possible to force heat to reside within this PTC thermistor element thus enabling efficient suppression of overcurrent by modifying the resistance value of such PTC thermistor...
