JUMO Wtrans B
Programmable Head Transmitter
with Radio Transmission
Brief 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 k
Ω , voltages up
to 50 mV, and currents up to 20 mA that use an external shunt are measurable. Customer-spe-
cific 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 un-
affected 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 re-
ceiver 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.
