What happened when a heat is applied to the joined ends of the wires of a thermocouple
What are the salient features of thermistors? 1. They are compact, rugged and inexpensive 2. They have good stability when properly aged 3. The response time of thermistors can vary from a fraction of a second to minutes, depending on the size of the detecting mass and thermal capacity of the thermistor
A J-type thermocouple has an output voltage Vθ = (13650 + 50 θx) μV, where θx is the junction temperature in Celsius (°C). The thermocouple is used with reference junction compensation, as shown in the figure. The Instrumentation amplifier used has a gain G = 20. If θRef is 1 °C, for an input θx of 100 °C, the output Vo of the instrumentation amplifier in millivolt is
Identify the instrument shown in the figure below:
