Wheatstone bridge measuring circuit |
摘要 |
Temperatures are automatically measured with a Wheatstone bridge including first and second branches and a diagonal connected between taps of the branches. The first branch includes first and second series connected resistors respectively having values of P and Q; the second branch includes third and fourth series connected resistors respectively having values of R and A. A voltage source, having a value E, is connected to energize the branches in parallel. The third resistor is temperature responsive and has a positive temperature coefficient so that the value of R is given by:
