Claims (1)

[Scope of Claim for Utility Model Registration] By touching the tip 3 of the voltage detection tube 2 at the end of the sensor body 1 to the object of voltage detection, with the inspector as the ground, depending on whether or not a potential difference is detected in the object of voltage detection. In the sensor which turns on and off the voltage detection display means 4 attached to the sensor body 1, the temperature sensor 9 is housed in the distal end 3 of the voltage detection tube 2 in a sealed state with an encapsulating metal 12. , by bringing the tip 3 into contact with the object to be measured, converting the thermal energy detected by the temperature sensor 9 into an amount of electricity, and displaying the temperature of the object on the temperature display section 11 disposed on the sensor body; A sensor for both voltage detection and temperature measurement, characterized in that the tip portion 3 is formed into a flat shape. The temperature T' displayed on the temperature display section 11 when the tip 3 of the electroscope tube is brought into contact with the object to be measured is subjected to a temperature increase process by a certain temperature range Δt relative to the actual temperature of the object to be measured at any given time. This fixed bulking temperature range Δt is the actual final temperature of the object to be measured at T, and the temperature of the object to be measured at the contact time n when the temperature gradient, which is the degree of temperature change with respect to the contact time, is constant. If the actual temperature of
At that time, the two displayed temperatures T' displayed on the temperature display section 11 are compared to find that the numbers in the predetermined digit are the same, but the numbers in the digits below the predetermined digit are different. When the gradient of temperature change is predicted to be within a predetermined range, it can be quickly determined by reading the displayed temperature T' displayed later of the two temperature measurements as the temperature to be measured. It is possible to measure the temperature by eye, and at least two times of temperature measurement mentioned above.
The difference in the displayed temperature T' is the difference in the numbers below the predetermined digit of the temperature number, and on the other hand, the temperature increase range Δt is the difference between the actual final temperature T and the actual temperature t when the temperature gradient is constant. Since it is the value after subtracting
The error between the read display temperature T' and the actual final temperature T is a difference within a predetermined order, and the read display temperature T' and the actual final temperature T are within a predetermined order. 2. The sensor for both voltage detection and temperature measurement according to claim 1, wherein the voltage detection and temperature measurement sensors are completely coincident with each other and can be measured quickly and accurately.
