Room temperature H S micro-sensors with anti-humidity

The humidity interference of the micro-sensors was studied by exposing the micro-sensors to the mixed gas of H 2S and humidity. The RH ambience of 75% RH (corre-sponding to NaCl) was obtained using a saturated salt solu-tion as the humidity generation source [14]. The response value (R) was designated as R=R a/R g, where RGet price

Humidity Sensors: RH/T Measurements | TE Connectivity

The Problem with Humidity in gaz sf6 Gas-Insulated Systems

Humidity in SF 6 Gas The SF 6 in the gas compartment can absorb a certain amount of water. When the amount of water exceeds the saturation point of the gas, the excess condensates and forms a water layer (if the gas temperature is above freezing) or sublimates and forms an ice layer (if the gas temperature is below freezing).Get price

Humidity Sensors - TI.com

The primary type of humidity information reported by these sensing ICs is Relative Humidity (RH). Relative Humidity can be described as the ratio of the amount of water vapor present in the air versus the amount of vapor the atmosphere can hold at a given temperature. The equation for relative humidity is shown in Equation 1. The differentGet price
