Abstract

The invention belongs to the technical field of temperature measurement, and particularly relates to a temperature difference value feedback sensor. The temperature difference value feedback sensor comprises a temperature sensing cylinder, wherein a first piston and a second piston which are matched are arranged in the temperature sensing cylinder, the first piston and the second piston are connected through a spring, the first piston and one end of the temperature sensing cylinder are matched to form a sealed first temperature detection part, the second piston and the other end of the temperature sensing cylinder are matched to form a sealed second temperature detection part, temperature sensing media are respectively filled in the first temperature detection part and the second temperature detection part, the temperature sensing media can expand with heat and contract with cold along with temperature change so as to drive the corresponding pistons to move, a first contact and a fourth contact which are opposite are respectively arranged on the opposite surfaces of the first piston and the second piston, and a second contact and a third contact which are arranged in the length direction of the temperature sensing cylinder are arranged on the inner wall of the temperature sensing cylinder. The temperature difference value feedback sensor can conveniently measure the temperature difference between two points in a heating system, has the characteristics of convenience, accuracy and the like, and is simple in structure.

Description

technical field [0001] The invention belongs to the technical field of temperature measurement, in particular to a temperature difference value feedback sensor. Background technique [0002] The general temperature measuring device can only measure the temperature. When it is necessary to measure the temperature difference, it is very inconvenient to calculate the temperature measured at two points, and the accuracy is not high. If the measured temperature changes, the general temperature measuring device cannot accurately complete the measurement of the temperature difference. In the hot water heating system, the temperature is constantly changing. Using the accurate temperature difference measured by the heating system, the heating system can be adjusted reasonably to balance the thermal power and save energy. Since the general temperature measuring device cannot accurately measure the temperature difference between two points in the heating system, it is difficult to imp...
