1.2 Description
The Wtrans B head transmitter with wireless data transmission is used in connection with a
Wtrans receiver unit for stationary or mobile temperature measuring with RTD temperature
probes or thermocouples. Alternatively, resistors with an ohmic-value of up to 10 kΩ, voltages
up to 50 mV, and currents up to 20 mA that use an external shunt are measurable. Customerspecific linearizations are possible.
The measured values are transmitted wirelessly to the receiver of the Wtrans measuring system. These values are shown on the receiver's LCD display and are digitally available on the
RS485-interface or as analog output(s). Optionally, different alarm types can be indicated with
the two relay outputs.
This head transmitter is designed for industrial applications – it is made up of the transmitter
with an integrated transmission unit and an antenna-battery case. The transmitter is designed
to be installed into type B terminal heads and works in an ambient temperature range from -30
to 85 °C. It is possible to install the transmitter into customer-specific terminal heads. The antenna-battery case is connected to the terminal head through a screw connection (M20 × 1.5).
The transmission frequency of the Wtrans measuring system is 868.4 MHz. This frequency is
unaffected for the most part by external interferences and it allows for transmissions even in a
rough industrial environment. When using the antenna wall-holder with the 3 m antenna line for
the receiver then the maximum open-air range is 300 m.
A 3.6 V, 2.2 Ah (size AA) lithium battery is used as a power supply for the transmitter. For the
easy configuration and parameterization of the head transmitter and the Wtrans receiver on a
PC an optional setup program is available. Additionally, measured values can be recorded on
the PC with the online-chart function.

4.1 General information about radio transmission
Radio signals are electromagnetic waves the signal of which will become weaker on their path
from the probe to the receiver (this is termed as path attenuation). The field strength reduces
inversely proportional in relation to the square of the distance between the probe and receiver.
In addition to this natural range restriction, a reduced range can also be the result of the following causes:
• Ferroconcrete walls, metallic objects and surfaces, heat insulation or windows with vapor
deposited metal layer reflect and absorb electromagnetic waves and, for this reason, a
deadspot is formed behind.
• Metal tubes, chains, etc. on the probe housing, for this reason, do not fasten any metallic
objects on the probe housing.
• Insufficient spacing between several probes, for this reason, ensure a minimum spacing of
20 cm.
• The antenna is installed at an insufficient height; install as high as possible above the floor
and ensure visual contact between the probe and receiver.
The following values are reference values concerning permeability of radio signals:
Material Permeability
Wood, plaster, glass uncoated 90 to 100 %
Brickwork, press boards 65 to 95 %
Armored concrete 10 to 90 %
Metal, aluminum lamination 0 to 10 %
The range between the probe and the receiver is 300 m in open air and when using the antenna
wall holder for the receiver. The optimum reception can be achieved, if visual contact can be
established between the probe and receiver.
If the receiver is installed into a switch cabinet, behind concrete walls or concrete ceilings, the
antenna must always be installed with the wall holder and antenna cable for the receiver pointing in the direction of the probes.

4.2 Possible impairment of radio transmission
Collisions when using an excessive number of probes
When using a large number of probes, do not select a transmission interval which is too low,
otherwise the radio channel will be unnecessarily occupied. A too low transmission interval
means a very high data volume on the selected frequency which can lead to collisions with other probes. Telegrams can be destroyed during radio transmission caused by collisions.
Figure 1: The telegrams of a probe reach the receiver without collisions.
Figure 2: Telegrams of several probes can collide.

Number of probes
Fault increase
Figure 3: Collisions depending on the number of probes
at a transmission interval of 1s
As the figure 3 shows, the error curve increases sharply once 24 probes are reached.
For this reason, we recommend using a maximum of 16 probes for the smallest transmission
interval of 1 s. For the factory setting of 15 s, a considerably larger number of probes is possible.
Estimation of the maximum number of probes
If more than the recommended 16 probes are to be used at a transmission interval of 1 s, select
a higher transmission interval to prevent an increased error quota.
Example:
16 probes at a transmission interval of 1s = 32 probes at a transmission interval of 2s
When the number of probes is to be increased additionally, the following calculation results in
the next example:
Example:
16 probes at a transmission interval of 1s = 48 probes at a transmission interval of 3s (theoretically)
However, from a transmission interval of ≥ 3 s, the telegram is transmitted twice. For this reason, the number of probes to be used is cut in half.
16 probes at a transmission interval of 1s = 24 probes at a transmission interval of 3s (effectively)
The identical behavior occurs from a transmission interval of ≥ 60s. From this transmission interval, the telegram is transmitted three times.
External probes
The ISM band can also be used freely by other devices. External probes can transmit on the
same frequency. If, for example, the probe and an external probe transmit their radio telegrams
at the same time, the telegrams are destroyed. Due to the fact, that the probes are not able to
check their own active transmission, no error is detected.
Electrical devices
In a rough industrial environment, radio telegrams can be destroyed, for example, by frequency
converters, electrical welding equipment or poorly shielded PCs, audio/video devices, electronic transformers, electronic ballasts, etc.

Error map-out
The radio transmission timeout parameter on the receiver can be used to map out lost telegrams (either by external influence or collisions caused by a large number of probes) and no
error message appears. The value received last is retained over 2...10 transmission intervals
and the alarm radio transmission timeout is only then activated (display "----").
TIP!
In the event of collisions caused by an excessive number of probes, observe and, if necessary, correct the factors "number of probes", "transmission intervals" and, on the receiver, "radio transmission timeout".

TIP!
At a transmission interval of > 15 s, the probe transmits a so-called link telegram (after a setup transmission), i. e. the telegrams are transmitted at the factory-set interval of 15 s for a
period of 30 minutes, and only then at the set transmission interval.
TIP!
Once the setup connector is connected, the probe automatically transmits telegrams at a
transmission interval of 1s to ensure that changes can be immediately detected by the receiver. After the setup connector is removed, the telegrams are transmitted again at the set transmission interval.
Term definition
Probe ID
The probe ID is an unmistakable ID with max. 5 characters which is recognized by the receiver.
The ID can be individually changed, for example, to achieve a better overview of a system. Ensure that an ID is not used simultanously by two probes within the reception range to avoid malfunctions.
7 Setup program
Transmission interval
This parameter is used to define the time intervals used to transmit data to a receiver. The setting of the "Transmission interval" parameter affects the battery service life. For this reason, act
with caution and do not only consider the transmission quality when selecting the interval.
Transmission frequency
The transmission frequency defines the frequency band used to transmit data to a receiver. The
transmission frequency is defined at 868.4 MHz for Europe because special regulations are defined concerning transmission interval and transmission capacity for the ISM band (Industrial,
Scientific and Medical Band).
