Abstract

The purpose of the invention is to provide a temperature controller synchronization degree tester and a testing method thereof. The temperature controller synchronization degree tester is used for detecting the synchronization of a snap-action temperature controller in order to increase detection accuracy and efficiency and decrease the labor intensity of workers. The temperature controller synchronization degree tester comprises a control device, a switch-off synchronization detection board, and a switch-on synchronization detection board. A heater is disposed in the switch-off synchronization detection board. Each of the switch-off synchronization detection board and the switch-on synchronization detection board is provided with a state detecting device and a sensing device. Each sensing device comprises a sound sensor and / or a vibration sensor and is connected with the control device. Each state detecting device is composed of a power supply and relay. One end of each power supply is connected with a first terminal clip and the other end of the power supply is connected with the first control end of the corresponding relay. The second control end of each relay is connected with a second terminal clip. The two terminals of the output circuit of each relay are connected with the control device.

Description

technical field [0001] The invention belongs to the technical field of thermostat testing, and in particular relates to a thermostat testing instrument and a testing method thereof. Background technique [0002] The snap thermostat (hereinafter referred to as the thermostat) is a temperature switch whose contacts are made of bimetallic sheets. The thermostat is in a normally closed state when it is low temperature. When it is heated to a certain temperature point, its contacts are disconnected; when it cools down to a certain temperature point, its disconnected contacts are closed again. [0003] The bimetal sheet of the thermostat will move when it is heated up or cooled down, and it will emit sound and vibration. During the heating process of the thermostat, measure the state of its contacts. When the bimetal makes sound and vibration, if the contacts are disconnected at the same time, it is considered that the product is synchronously qualified, which is called disconnec...
