An electric actuator humidity monitoring and alarm circuit

Abstract

The invention relates to a humidity monitoring alarm circuit of an electric actuator. The humidity monitoring alarm circuit of the electric actuator comprises a humidity sensor, a humidity signal conversion circuit, a humidity frequency signal circuit, a counting circuit, a frequency displaying circuit and an alarm circuit, wherein the humidity sensor is connected with the humidity frequency signal circuit and the alarm circuit through the humidity signal conversion circuit, the humidity frequency signal circuit is connected with the counting circuit, and the counting circuit is connected with the frequency displaying circuit. According to the humidity monitoring alarm circuit of the electric actuator, humidity inside the box body of the electric actuator is monitored in real time by means of the humidity sensor, alarm prompt and digital display can be carried out when the humidity inside the box body is over-high, and therefore the problem that a user can not learn the humidity inside the box body of the electric actuator all the time is solved, damage to a large number of components and mechanical parts caused by the use of a space heater inside the box body of the electric actuator is avoided or reduced, practical environment adaptive capacity of the electric actuator is greatly improved, and a basis is provided for the use of the electric actuator in a severer environment.

Description

technical field [0001] The invention relates to electric actuators, in particular to a humidity monitoring and alarm circuit for electric actuators. Background technique [0002] The operating environment of electric actuators has always been relatively harsh, especially in humid and rainy environments, it is easy to cause damage to circuit boards and components due to excessive humidity in the box, and corrosion of multiple parts of the reducer. For this reason, many manufacturers have A space heater is added to the electric actuator box, which can solve the problem of high humidity, but at the same time, because the instant humidity of the box cannot be judged, the long-term use of the space heater will cause the circuit board and components to overheat and be damaged. And other mechanical parts accelerate wear due to long-term exposure to hotter environments. Users have been unable to grasp the humidity in the electric actuator box, which has become a huge obstacle restr...
