Description
Duct temperature and humidity sensor with a measuring element, consisting of a combined temperature/humidity
sensor, the filter element sinter filter and a VOC measuring element for measuring indoor air quality.
VOC (Volatile Organic Compounds) are the air pollutants of volatile organic substances in the air. By using additional temperature sensors, measuring errors can be avoided. Possible causes: own heating of the electronics used in a group unit, draught air, direct sun radiation, cold outside walls…
- Measuring range VOC measuring element index 0 …500
- Measuring range temperature -35 …+70 °C
- Measuring range humidity 0 …100 % r.h.
- Output of sensor values and parameters to data points for further processing
- Output to data points:
– Humidity, air density, saturation vapour pressure, water vapour partial pressure, absolute humidity, dew point, wet bulb temperature, enthalpy, air pressure - Adjustable parameters: Offset, damping, resolution …
- Monitoring of the sensor (error messages) and the communication (online status)
- Flexible wiring of the fieldbus: star, series or parallel
- Power supply via F-bus (2-wire), no extra power supply required
- Controlling, programming and feedback is effected via the F-bus (2-wire)
- Automatic parameter transfer after address assignment
- Extended diagnostic options, error statistics, reporting and display of device data
- Firmware update possible during operation via F-bus
- Up to 32 participants per line
- Own data point bar (analog/digital) for each participant
- Fast data update through event-oriented communication
Plastic housing for wall mounting.
Measuring element, consisting of a combined temperature/humidity sensor, filter element sinter filter and VOC measuring element, available as spare part under Art. No. G 04 12 14 (STHVOC HD-PE).
