HIH8120-021-001S Sensors, Transducers

Humidity, Moisture Sensors are becoming increasingly popular in many applications. The HIH8120-021-001S is one such sensor manufactured by Honeywell International, Inc specifically for measuring humidity. This article will outline the HIH8120-021-001S’s application field and working principle.Humidity sensors are used in a wide variety of applications ranging from medical diagnostics to industrial processes. The HIH8120-021-001S is designed to measure relative humidity in samples of air or gas. It has a very high accuracy, allowing it to detect even small variations in humidity levels. This makes it ideal for use in industries such as food processing, HVAC, pharmaceutical production, and petrochemicals. The sensor itself is very small and is available in a number of different packages ranging from surface mount to enclosed modules.The HIH8120-021-001S operates by measuring the water vapor pressure created when the sample air or gas is exposed to the sensor. The humidity in the sample is then calculated by comparing the water vapor pressure to the total atmospheric pressure. This principle is known as the Psychometric Method of Relative Humidity Measurement. The HIH8120-021-001S employs a capacitative sensor element to do this, which is enclosed in a hermetically sealed stainless steel package.The capacitative sensing element of the HIH8120-021-001S consists of a thin-film capacitive element, separated by a permeable membrane. When exposed to the sample air, the humidity levels in the sample cause a change in the capacitance of the thin-film element. This change in capacitance is then measured and analyzed by the sensor to calculate the relative humidity. It is important to note that the sensitivity of the HIH8120-021-001S may vary according to the sample air conditions, as different humidity levels will cause different changes in capacitance.The HIH8120-021-001S offers a number of additional features which make it an ideal choice for measuring relative humidity. It is able to measure relative humidity levels up to 100%, and offers a very high accuracy of ±2%RH at 25°C. It also offers a fast response time of up to 5 seconds, and features built-in temperature compensation which improves accuracy and reliability.In conclusion, the HIH8120-021-001S is an excellent choice for applications which require fast, reliable, and accurate measurement of relative humidity levels. Its small size and versatile options make it ideal for a variety of industries, and its additional features provide improved accuracy and reliability.
