Data logger models in waterproof housing
In order to highlight the physical quantities measured by data loggers, order codes include
some identification characters for the various quantities, according to the following convention:
1
= Humidity
4b
= Atmospheric Pressure (barometer)
N
= Temperature with NTC10K sensor (
N/2
=two channels,
N/3
= three channels)
7P
= Temperature with Pt100/Pt1000 sensor (
7P/3
= three channels)
R
= Solar radiation (pyranometer)
P
= Rainfall quantity
V
= Acceleration
TC
= Probe with cable
TV
= Fixed vertical temperature and/or R.H. probe without cable, with high accuracy R.H.
sensor
TVI
= Fixed vertical temperature and R.H. probe without cable
Models measuring temperature and humidity with combined probe with cable (
…TC
models) use
the probes of the
HP3517…
series with
high accuracy
relative humidity sensor
and
NTC 10K
Ω
@ 25 °C or Pt100 temperature sensor according to the model.
The replacement of
the HP3517… probe requires instrument recalibration in line with the new probe
.
Models with M12 connectors equipped with inputs for the measurement of temperature only use
TP35…
series temperature probes with NTC 10K
Ω
@ 25 °C or Pt100/Pt1000 sensor.
In models with 2 or 3 M12 connectors, the input number is shown on the connector side.
In models measuring the atmospheric pressure, the sensor is inside the instrument.
Refer to the figures indicated in the last column of the table below for probes connection
modes and the position of the integrated sensors in the various models.
