Demodectic Mange in Dogs. Demodicosis in Dogs. Mange (demodicosis) is an inflammatory disease in dogs caused by various types of the Demodex mite. When the number of mites inhabiting the hair follicles and skin of the dog become exorbitant, it can lead to skin lesions, genetic disorders, problems with the immune system and hair loss (alopecia).
There are numerous sensors available for temperature measurement under the name thermal sensors. Popular ones are the thermistor, thermocouple, RTD. Diodes can be used to sense temperature due to the change in their forward voltage with change in temperature. One of the advantage of using diodes is they have a nearly linear relationship between temperature and voltage applied.
How to test an engine coolant temperature sensor. An engine coolant temperature sensor is usually a variable resistor that changes resistance and thus voltage as the coolant temperature changes. To test the sensor, you can remove the electrical connector and check the resistance value of the sensor and compare it to specs. If itâs way off, replace it. But if itâs close, you really need to perform a voltage test, since itâs far more accurate than an ohm test.
