Combined Temperature / Relative Humidity Sensor

A combined sensor designed for monitoring air temperature and relative humidity in meteorological and environmental applications.
The EMCON Combined Temperature / Relative Humidity Sensor is an environmental monitoring instrument designed for accurate and reliable measurement of air temperature and relative humidity. The sensor combines a Pt.1000-based air temperature sensing element with a capacitance-based relative humidity sensor. Its low power consumption and ability to support long cable connections make it suitable for remote and centralized measurement systems. The sensor is designed for long-term operation, including use in hostile weather conditions, with dust-resistant construction and excellent long-term stability. The temperature sensor offers selectable measurement ranges, while the humidity sensor measures relative humidity from 0 to 100%. Linear voltage outputs can be provided according to customer requirements, making the sensor suitable for integration with data acquisition systems and environmental monitoring equipment.

Combined Temperature / Relative Humidity Sensor

The EMCON Combined Temperature / Relative Humidity Sensor is designed for
scientific and environmental observations where reliable measurement,
accuracy, and long-term stability are essential. The instrument combines
air temperature and relative humidity measurement in a compact sensor
assembly.

Air Temperature Measurement

The air temperature sensing element uses a Pt.1000 type sensor. Multiple
selectable temperature ranges are available to meet different monitoring
requirements.

Relative Humidity Measurement

Relative humidity is measured using a capacitance-based sensing element.
The sensor provides measurement from 0 to 100% relative humidity with a
corresponding linear voltage output.
