The working principle of a capacitive relative humidity sensor is to utilize the water absorption properties of polymers to cause changes in the electrolyte inside the capacitor. Polymers can quickly balance with the humidity of the environment and then change the corresponding capacitance value according to the level of humidity. highlight Suitable for corrosive gases PTFE coatings Capacitive ultra-thin thin film sensor Measurement range: 0-100% RH, temperature: -30 to+200 ° C Mixing ratio: 250g moisture/kg dry air No lag Response time: 20 seconds
