SensoData 5500 7–Operator’s Manual
Relative humidity probe is located outside on the top of cylinder of the measuring module. The probe includes a
capacitive polymer sensing element for relative humidity and a bandgap temperature compensation sensor. Each
probe is individually calibrated in a precision humidity chamber with a chilled mirror hygrometer as reference.
Technical Data:
- measurement range: 0…100 % RH
- accuracy: ±2% w zakresie 10…90% RH
- long term stability: <1% RH/rok
- response time: <4s
B. SensoData 5500 Anemometer
The SensoData 5500 Anemo is a device for the air speed and temperature measurement. The device enables
measurements of jet ventilation and effectiveness of the ventilation in rooms as well as measurements of flow of
inside different devices. SensoData 5500 Anemo B with the built-in pressure sensor can read the barometric
pressure and enables the automatic correction of
anemometer readings at changes of the barometric
pressure. The device has the DSubHD15 socket for
connecting probes (see photo). The RJ45 socket from the
side of the casing enables to connect additional external
transducers or modules, so as: SensoAnemo transducer,
SensoHygBar transducer, SensoTCMod thermal comfort
module. So that it is possible significantly extend the
functionality of the device. The device meets the
requirements of following standards: ISO 7726, ISO
7730, EN 13182 and ASHRAE 113.
Spherical omnidirectional probe SF enables measurements of jet ventilation and effectiveness of the
ventilation in rooms. Includes the spherical omnidirectional air speed (1) and compensation temperature (2) sensors.
Both the sensors are vacuum covered with special aluminium coating that increases their resistance to contamination
and decreases the effect of thermal radiation on the accuracy of velocity measurement. The temperature sensor (2)
can be additionally protected against radiation using moving shielding tube (3) (it may be necessary only if the
airflow is measured very close to high temperature sources). Both sensors can be also protected against mechanical
damage using openwork basket (4) made with wire circles. If such a protection isn't necessary it is possible to
removed them from the shielding tube (3). Shielding tube (3) can be moved along the support of the probe and
locked by the clamp screw (5).
Technical Data:
- diameter of the speed sensor: 2 mm
- measuring range: 0.05…5 m/s and -20…50OC
- resolution: 0.001...0.01 m/s and 0.1OC
- accuracy: ±0.02 m/s ±2% and 0.2OC
- directional error above 2m/s: ±2.5%
- automatic temperature compensation:< than ±0.1%/K
- upper frequency ƒup2): min. 1Hz, typ. 1.5 Hz
1) The additional error caused by the different reaction of the spherical
sensor above speed of 2m/s to the change of air flow direction with
respect to direction established in the calibration.
2) The upper frequency is defined as the highest frequency up to which
the standard deviation ratio remains in the limits of 0.9 to 1.1 in relation
to the standard deviation of the frequency 0 Hz (see the ASHRAE
Transaction Vol.1,1998, paper No SF-98-20-2).
