A. SensoTCMod module
Measuring modules of the thermal comfort are made in the form of cylinders with dimensions of 100x48mm.
The SensoTCMod 5506 module includes following transducers: anemo, thermo, hygro. The SensoTCMod 5507
includes additionally barometric pressure sensor. The SensoTCMod 5503 module includes anemo and thermo
transducers, but doesn’t include baro and hygro transducer. Air temperature and relative humidity sensors are
placed on the top of the cylinder. Natural wet temperature, globe temperature and air speeds sensors are placed on
lateral horizontal supports. Air speed probe can be disconnected from the measuring module and may be
transported, stored or calibrated separately. The measuring modules can be mounted on a special folding tripod,
which enables mounting three or four units at the different heights.
Air speed probe 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 by 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
- measurement speed range: 0.05…5 m/s
- resolution: 0.001...0.01 m/s
- accuracy: ±0.02 m/s ±2% of readings
- automatic temperature compensation: < than 0.1%/K
- temperature compensation: -20OC…50OC
- upper frequency fup*): min. 1Hz, typ. 1.5 Hz
*)
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).

ThermCondSys 5500 5 –Operator’s Manual
Preparation for measurements:
1. Check if the openwork basket (4) is on the shielding tube (3). If not, put openwork basket (4) on the shielding
tube (3). Be particularly careful not to damage the speed sensor (1). To this purpose check if the shielding tube
(3) is on the end of the probe completely covering the speed sensor and the clamp screw (5) is properly locked
(it does not move). Put on the openwork basket (4) only then when the sensor (1) is covered by the shielding
tube (3).
2. Connect the air speed probe to measurement modules. Loosen the clamp screw (5) and move the shielding tube
(3) with the openwork basket (4) into the bottom uncovering the sensors (1) and (2).
3. Lock the clamp screw (5).
4. After the measurements move the shielding tube (3) back on the sensors (1) and (2).
5. The probe should be transported in the carrying case only with imposed openwork basket (4).
Air (ta), globe (tg) and natural wet (tnw) thermometers measure temperature using RTD sensors. Automatic
correction of thermal drift provides high measurement stability. The use of insulating elements in design of probes
(special wood and fiberglass) guarantees the appropriate thermal insulation and high measurement accuracy. In
order to improve the accuracy each sensor is individually calibrated.
Technical Data:
- type and diameter of thermometer: ta: Pt-100 cylindrical Ø 2.6 mm
tg: black globe ε0.95, Ø 70 mm, tickness 1.5 mm
tnw: Pt-100 cylindrical, length 30 mm, Ø 5 mm; support Ø 5 mm
- measurement range: ta: -20…60 OC
tg: -20…120 OC
tnw: 0…50 OC
- accuracy: ta: ±0.3 OC
tg: ±0.3 OC for range -20..50 OC i ±0.5 OC for range 50..120 OC
tnw: ±0.3 OC
- stabilization time of measurement: 15…20 min
Barometric pressure probe is located inside the cylinder of the measuring module. The probe utilizes specialized
piezoresistive micro-machined sensing element. Each probe is individually calibrated and thermally compensated.
The calibration coefficients are programmed into EEPROM memory.
Technical Data:
- measurement range: 500…1500 hPa
- accuracy: ±3 hPa
- response time: 2s
Relative humidity probe (optional) 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: typ. ±1,5% in range 10…90% RH,max ±3%
- long term stability: <0.25% RH/rok
- response time: <4s
B. SensoBee wire-less transmitter
The SensoBee transmitter contains an RF module for
wire-less data transmission. The RF module operates
under ZigBee (802.15.4) protocol accepted by ETSI/EC
(Europe), FCC (U.S.A) and IC (Canada). The
transmitter should be powered by an external power
supply adapter or by PowerBank. RF switch should be
in the position RF and RF led should flash.
Measurement modules must be connected to the socket
B. In the case of the absence or errors in the wire-less

ThermCondSys 5500 6 –Operator’s Manual
transmission, the socket A enables optional wired connection of the transmitter with wire-less receiver. To do this,
move RF switch to the Off position, the RF led is not lit. The transmitter is equipped with a latch for mounting it in a
DIN rail.
Technical Data:
indoor (urban) range: up to 60m
outdoor line-of-sight range: up to 100m
transmit power output: 100mW (20dB)
operating frequency: 2.4GHz
RF data rate: 250 kbps
power supply: 5…9 VDC/1A
Remark:
Pay attention that the power supply adapter should have the voltage polarity on the plug compatible with
power socket in the casing (+ out).
C. SensoBeeUSB wire-less receiver
The SensoBeeUSB wire-less receiver contains the
RF module for wire-less data transmission. It enables
wire-less data transmission between transducers (via
SensoBee) and USB port of computer. The RF module
operates under ZigBee (802.15.4) protocol accepted by
ETSI/EC (Europe), FCC (U.S.A) and IC (Canada). The
receiver is being powered from the USB port of
computer (RF led flashes when connected to USB port),
therefore it doesn't require the use of external power
supply adapter.
The SensoBeeUSB can also be used for wired data
transmission. In this case, you should:
-connect to the RJ45 socket one end of the
connecting cable and the other end depending on the configuration, either directly to one of the measurement
module or SensoBee wire-less transmitter
-RF switch in the SensoBee transmitter change from RF position to Off (disable RF module).
Power socket placed on the side of the casing is used to connect the power supply adapter in case of direct power
connection to the measurement modules without using the SensoBee wire-less transmitter.
D. SensoConnect USB interface
The SensoConnect USB interface enables data
transmission to a computer through the USB port. It is being
powered from the USB port of computer, therefore doesn't
require external power supply adapter. The power socket
located on the side of the casing allows the user to connect an
external power supply adapter used to power the measurement
modules. The USB led indicates the connection interface to the
computer.

A. PowerBank
PowerBank is a high performance external battery pack with latch for DIN rail. The latch allows for easy
installation of the device on a tripod along with other parts of the measuring system. Includes a charging cable (USB
to micro USB) and spiral power cable (USB-plug DC) with a length of 30-100 cm.
Technical Data:
Power port: 2 x USB DC 5V/1A
Real capacity*): 7000mA or 1400mA
Minimum supply current: 135mA
Charging port: micro USB 5V/2.1A max
Charging time: >15 h
Long time efficiency: 300 cycles of full charge and discharge cycles will leave 85% of nominal
capacity)
*) Capacity due to reduced efficiency when converting from battery voltage 3.6 V to output voltage 5V (theoretical
capacity of the battery is 10000mAh or 20000mAh)
Remarks:
1. Turn off the PowerBank by disconnecting the power cable when you
are finished working. Otherwise, this may lead to rapid discharge of
the battery.
2. Charge and discharge the device once every 3 months, if it is not used
for a longer period of time.
3. Due to the minimal supply current, PowerBank may automatically turn
off after a few seconds in the case of smaller receivers power supply
current consumption (for example: a single SensoAnemo transducer).
Proper operation is achieved when are powered at least two
SensoAnemo transducers and SensoBee wire-less transmitter.
4. See picture next to how to connect the PowereBank with SensoBee
wire-less transmitter.
