Temperature Sensors, Electronic
Humidity Sensors
Temperature sensor
(PT-100): accurate and
very
stable in a wide temperature range installed in a
stainless steel probe.
Measuring range: -50 to +50 °C or 0 to +100 °C
The tempertature sensor serves for readings of air,
water of growth media, temperature.
Electronic humidity sensor (accuracy +/-3%) with a
4-20 mA output
Dry-wet temperature and humidity sensor (psychrometer).
Based on a pair of temperature sensors installed in
ventilated cell. One of the sensors is covered with
special sleeve, dipped into distilled water. The
difference between two measurings of the sensors
read by the controller, is calculated through a
psychrometric table and presented as relative
humidity (%). This kind of sensor is especially
designed for high humidity levels, more accurate and
cheaper than electronic sensor. It
requires a periodical
maintenance (once at 2-3 weeks).
Solar Radiation (P.A.R.) - for measurement of light
intensity in the range of photosynthesis activity.
Wind speed sensor (with analog output 4-20 mA).
Wind direction sensor (with analog output 4-20 mA).
Rain meter- records every 0.2 mm of rain. |
