Non-contact heating temperature controller performance testing device

Abstract

The invention relates to a non-contact heating temperature controller performance testing device, which is capable of well solving the problems affecting the accuracy of tests in the prior art. The key points of the technical scheme are as follows: the device comprises a temperature controller heating testing system for performing sample testing heating, a cooling system for cooling the temperature controller heating testing system, a subordinate control system for directly controlling the temperature controller heating testing system and the cooling system, a test data system for collecting test data and a host control system; the data testing end of the temperature controller heating testing system and the data testing end of the cooling system both are electrically connected to the test data system; an output end of the test data system is electrically connected to the host control system; an output end of the host control system is electrically connected to an input end of the subordinate control system; and an output end of the subordinate control system is electrically connected to control ends of the temperature controller heating testing system and the cooling system, respectively. The non-contact heating temperature controller performance testing device is quite accurate in test detection.

Description

technical field [0001] The invention belongs to detection and monitoring devices, in particular to a temperature controller performance testing device capable of performing accurate testing. Background technique [0002] As an important component of household and similar products, thermostats have attracted much attention in the industry for their reliability and stability. GB14536.1-2008 and GB14536.10-2008 have specific requirements for the durability and accuracy of thermostat Requirements, however, with the development of technology and the improvement of product performance requirements of complete machine manufacturers, the industry's performance requirements for thermostats are also gradually increasing. In addition to the mechanical and electrical life of the thermostat, the time constant of the thermostat , Thermostat manufacturing deviation, drift, reset characteristics, and the influence of ambient temperature change rate on thermostat performance and other techni...

AI Technical Summary

Problems solved by technology

However, this technical solution still has the above three problems: first, there is an obvious temperature overshoot in the system, which affects the accuracy of the test; second, the existence of environmental stress will cause additional drift in the performance of the thermostat, affecting the durability of the thermostat The test and the determination of the drift of the thermostat. Third, due to the existence of cooling air, it does not match the actual working conditions of the thermostat, which in turn affects the test results.
