Skip to the content Atmospheric sensors include temperature, humidity, atmospheric pressure sensors, and barometric pressure, Particulate Matter (PM) and Air Quality (AQI). Temperature, humidity and barometric pressure have been used for research and weather forecasting for centuries. PM and AQI are becoming more common with concerns about air quality and health. Comptus sensors are designed for connectivity to data loggers, monitors and system controls.
Atmospheric sensors that detect temperature are thermistor devices. Based on the current conditions, the sensor’s electrical resistance changes. A reference voltage applied to the sensor views the voltage signal received, which is how it comes up with an accurate calculation.
Surface temperature transmitters are designed for applications requiring direct contact surface temperature monitoring. The device includes a high temperature adhesive to ensure contact with the surface. The paste type sensor is well suited to commercial and industrial applications where a correlation between temperature and performance are measured, such as photovoltaic (PV) panels.
Another atmospheric pressure sensor measures the level of air pressure in the atmosphere. The internal aneroid cell measures the degree of weight produced by air molecules. Most often, meteorologists use these atmospheric sensors to forecast the weather. Facility operators will monitor barometric pressure for a number of reasons including pressure balancing large structures. These sensors often work alongside atmospheric pressure transducers to provide accurate data.
Leonardo Da Vinci is credited with inventing the hygrometer, or humidity sensor. Modern devices detect changes that alter electrical currents or temperature in the air. There are three basic types of humidity sensors: capacitive, resistive and thermal. All three types will monitor minute changes in the atmosphere in order to calculate the humidity in the air.
The A70H-HTP humidity, temperature and pressure sensor is an example of what we offer. They’re ideal for input to control systems or used in combination with electronic data collection systems. Additionally, devices like an ambient pressure sensor help monitor and balance environmental conditions.
