Humidity and moisture sensors play a critical role in a variety of industrial and commercial applications, as they provide essential information for monitoring, measuring, controlling, and managing climate-related variables. The HIH-4000-001 is a highly versatile humidity and moisture sensor that is widely used in a broad range of industries for measuring relative humidity, temperature, or both. This article explores the HIH-4000-001 application field and working principle.

HIH-4000-001 Application Field

The HIH-4000-001 is primarily used in industrial climate control systems where precise monitoring of temperature and humidity is critical. It is used extensively in smaller-scale applications such as commercial greenhouses, agricultural environments, and commercial bakeries. Additionally, it is ideal for larger-scale climate control applications such as water purification, freshwater aquaculture, and industrial climatizers. It is also used in laboratory testing and research, as well as industrial production processes.

Working Principle of HIH-4000-001 Humidity and Moisture Sensors

The HIH-4000-001 incorporates both a humidity and a temperature sensor on the same circuit sandwiched between two thermoplastics. The humidity sensor is a simple capacitive element which operates on a very basic principle; relative humidity is proportional to the distributed moisture on the capacitive element. The element is in contact with the air, and when air with moisture is present the capacitance will slowly increase. The two thermoplastics act as a guard against high temperatures that could damage the humidity element. The temperature sensor, meanwhile, uses thermistor technology or a thermocouple in order to measure temperature independently of the humidity element.

The HIH-4000-001 in capable of transmitting the data to a controller either via a 4-20 mA signal, or a variable voltage via a Pt1000 element. It also has the capability to output a voltage signal depending on the temperature and the humidity that is measured. These two parameters (voltage and current) make it possible to measure the humidity and temperature information all at once. With this information, it is possible to do a multitude of things such as set alarms, shut off valves, activate relays, etc.

Conclusion

The HIH-4000-001 is an incredibly versatile humidity and moisture sensor that is widely used in a variety of industrial and commercial applications. Its two main components, a humidity element and a temperature sensor, combined with its outputs of both current and voltage, make it possible to measure and monitor the humidity and temperature of any environment. This information can then be used to control or manage climate variables and take appropriate action.
