Ambient Temperature and Humidity Sensors
HygroVue 10
The HygroVue™10 offers a combined temperature and relative humidity element in an advanced digital sensor that is ideal for weather networks. The electronics within the sensor provide accurate measurements, and the sensor is easy to use. The digital SDI-12 output allows a simple connection and measurement by many data logging systems. Another benefit is that this digital output avoids the extra errors associated with measuring analog sensors.
A hydrophobic sintered filter prevents dirt and water from entering the cap. The filter is designed to be resistant to wind-driven rain. A secondary PTFE membrane filter is bonded to the surface of the sensor element to prevent finer dust and mold from directly influencing the measurements.
Because the sensor housing is designed to withstand permanent exposure to various weather conditions and to fit inside a range of radiation shields (including compact shields), the HygroVue 10 is truly suitable for a wide range of monitoring applications.
The HygroVue 10 uses a latest-generation, Swiss-made, combined relative humidity and temperature element based on CMOSens® technology that offers good measurements, accuracy, and stability. Each element of the HygroVue 10 is individually calibrated with the calibration corrections stored on the chip. You can easily change the sensor element in the field, which reduces your downtime and calibration costs.
Benefits and Features:
- Uses a combined, pre-calibrated digital humidity and temperature element
- Field-changeable element for fast, on-site recalibration
- Digital SDI-12 output, allowing long cables with no added errors
- Simple data logger programming
- Low power consumption
- Wide operating voltage
- Rugged design with potted electronics
- Standard M12 connector with IP67 sealing rating
HC2A-S3
The standard Rotronic Humidity and Temperature probes can be used in application with temperatures from -50…100 °C / 0…100 %RH. With an outstanding accuracy of ± 0.8 %RH / ± 0.1°C. For calibration purposes the probes can be replaced without almost any downtime. With weather shield the HC2A-S3(H) probe is the first selection for many applications.
The HC2A-S3(H) are most used versatile probe and form the basis of the meteorological and outdoor application product portfolio. They measure Humidity and Temperature and can calculate the dew-/ frost point.
Key features :
Range of application -50…100 °C / 0…100 %RH
Accuracy: ±0.8 %RH, ±0.1 K, at 23 °C ±5
Digital interface (UART) and scalable analog outputs, 0…1 V
