Produktbeschreibung

universal 3-channel multi-function data logger with graphic display

general information:

HD 31 is a universal data logger with the capacity to connect up to 3 "SICRAM" probes. All relevant data (serial number, type, calibration data) is stored in the SICRAM plugs, so
the probes can be connected in any arbitrary manner. The connected probe is recognised automatically by HD 31. Additional variables can be derived from the measured values. For example, the dewpoint temperature, wet-bulb temperature, absolute humidity, etc. can be calculated from the temperature and humidity. A total of 36 different measured variables is available. Large-format colour display for presentation of three measuring values in numerical form or a real-time graphic.

The data is stored in CSV format on an SD card (storage capacity for several months, even if multiple measured variables are logged each second). The HD 31 can be connected via the optional USB cable directly to a PC and is recognised as a mass storage device. HD 31 also generates automatic PDF logs, which are also stored on the SD card.

applications:

The variety of measuring sensors and the derived measured variables enable a wide
spectrum of applications, such as heating, ventilation and air conditioning or clean room
applications. The following measuring variables can be detected:

temperature
relative humidity
pressure (absolute, relative or differential pressure)
air speed
illuminance (Lux)
irradiance (W/m²)
CO₂

From the mentioned measuring units numerous variables can be calculated, displayed and stored. This includes, for example, the absolute humidity in g/m³ (from temperature and relative humidity) or the volume flow at measurements in ventilation ducts (from the speed and the dimensions of the ventilation duct), etc.

Furthermore SICRAM modules for the connection of external sensors with analog output signals are available:

VP 473: SICRAM plug module for signal recording of external measuring transducers with voltage output, measuring range ±20 V DC, input impedance 1 MΩ.

IP 472: SICRAM plug module for signal recording of external measuring transducers with current output, measuring range 0 mA to 24 mA, input impedance 25 Ω.

VP 472: SICRAM plug module for connection of pyranometers and albedometers with non-amplified signal output (adjustable sensitivity from 5 µV to 30 μV per W/m²).
