    摘要: A thermal probe system has a Wollaston thermal sensor connected in one arm of a bridge. The other arms of the bridge are provided by resistors and a voltage is applied from a low-noise source via several op-amps. The output of the bridge is connected with a primary winding of a step-up transformer, the output of which connects with the input of an output amplifier, which, in turn, provides an output to a display.
