Abstract
PURPOSE:To read out a temperature deviation at several points in an absolute value with a simple and low-cost device, by providing a compensation circuit on a temperature indication adjuster containing a zero compensation circuit for indicating a temperature from a temperature measuring section as thermocouple in a directly readable state to cancel bias of the zero compensation circuit. CONSTITUTION:A control box 14 of a concrete strength managing device 10 is provided with a temperature measuring device 11 where a temperature indica tion adjustor 30 is arranged and a power source is supplied to the adjustor 30 from three-phase AC R and S through a push button type normally opening contact SS1 and a fuse (f). A compensation circuit 31 is connected in parallel and moreover, relays RY1, RY2, H, AM and the like are connected in parallel. Thermocouples A and B are connected to the adjustor 30 in parallel and the thermocouple A is inserted into concrete sample S while the thermocouple B into a water tank 12. Temperature measured with the thermocouplers A and B is inputted into the adjustor 30 and bias of the zero compensation circuit within the adjustor 30 is cancelled with the circuit 31. The thermocouples A and B are connected alternatively to the adjustor 30 and the circuit 31.
