Terminal header in the model HD35EDWH
The model HD35EDWH is equipped with four terminal header inputs. Each input can be configured as input for: Pt100/Pt1000, thermocouple,
0/4...20 mA (the shunt resistance is internal), 0...50 mV, 0...1 V, 0...10 V or potentiometer. Only input 4 can also be configured as pulse counter
(counting of switchings of a voltage-free contact).
The model HD35EDWH is also available with 7...28 Vdc external power supply (HD35EDWHE, without battery).
Version for weather stations (HD35EDM...TC)
An IP67 waterproof version is available for meteorological applications, in a housing with front dimensions 120x122 mm. The model has:
- one input for relative humidity and temperature with NTC sensor combined probe or, alternatively, for temperature only probe
with NTC sensor;
- one input for pyranometer;
- one input for rain gauge;
- one input for cup anemometer;
- one input for wind direction vane;
It is also possible to connect only some of the probes.
Internal sensor for measuring the atmospheric pressure.
Calculated quantities (depending on the sensors available):
- dew Point;
- daily solar radiation in Wh/m
- ainfall rate in mm/h;
- rainfall statistics;
- Felt air temperature as a function of the wind speed: Wind Chill index;
- wind gust: maximum wind speed obtained from the 3 seconds averages of the measurements acquired once per second;
All the values acquired by the data logger can be simultaneously displayed in real time on the monitor of the PC.
