Abstract

The invention belongs to the technical field of sensors and relates to a damping type humidity sensor. The damping type humidity sensor comprises a sensor main body and a detection head body. The damping type humidity sensor further comprises a safety protection movable supporting seat assembly; the safety protection movable supporting seat assembly comprises a bottom plate, side vertical plates and a fixed top plate; a supporting plate is fixed onto the inner sides of the two side vertical plates; mounting strips are respectively fixed to the left end and right end of the sensor main body; the opposite surfaces of the side vertical plates are fixedly provided with supporting bracket assemblies respectively; and a pressing assembly is fixed onto the lower surface of the top plate. The safety protection movable supporting seat assembly is adopted; the stable movement of the sensor main body can be facilitated; workload is reduced; safety protection is realize for the sensor main body; the installation and dismounting of the sensor main body are convenient; the installation of the sensor main body is stable; and the smooth proceeding of subsequent detection work is facilitated. A limiting module can limit and support the sensor main body during the movement process of the safety protection movable supporting seat assembly, and therefore, the stability of the sensor main body is improved, and detection precision is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a shock-absorbing humidity sensor. Background technique [0002] The humidity sensor is the simplest humidity sensor. There are two types of humidity sensitive elements: resistive and capacitive. The characteristic of the humidity sensitive resistor is that the substrate is covered with a film made of moisture-sensitive material. When the water vapor in the air is adsorbed on the moisture-sensitive film, the element Both the resistivity and resistance value of the sensor change, and humidity can be measured by using this characteristic. Humidity sensitive capacitors are generally made of polymer film capacitors. Commonly used polymer materials are polystyrene, polyimide, and acetic acid Fiber, etc., when the ambient humidity changes, the dielectric constant of the humidity-sensitive capacitor changes, so that the capacitance also changes, and the capacitance change is proportion...
