1.1 Safety information
General
This manual contains information that must be observed in the interest of your own safety and to avoid
material damage. This information is supported by symbols which are used in this manual as indicated.
Please read this manual before starting up the device. Store this manual in a place that is accessible to
all users at all times.
If difficulties occur during startup, please do not intervene in any way that could jeopardize your warranty
rights!
Warning symbols
CAUTION!
This symbol in connection with the signal word indicates that material damage or data loss will occur
if the respective precautionary measures are not taken.
CAUTION!
This symbol indicates that components could be destroyed by electrostatic discharge (ESD = Electro
Static Discharge) if the respective cautionary measures are not taken.
Only use the ESD packages intended for this purpose to return device inserts, assembly groups, or as-
sembly components.
Note symbols
NOTE!
This symbol refers to important information about the product, its handling, or additional benefits.
READ THE DOCUMENTATION!
This symbol, which is attached to the device, indicates that the associated documentation for the de-
vice must be observed. This is necessary to identify the nature of the potential hazard, and to take
measures to prevent it.
REFERENCE!
This symbol refers to additional information in other sections, chapters, or other manuals.

1.2 Brief description
The Wtrans E01 measuring probe is used in combination with a Wtrans receiver for recording measured
values using digital sensors for humidity, temperature, and CO
2
. The measuring probe has two inputs
with plug connectors M12 × 1 to which the sensors can be connected and where the sensors are detect-
ed in any combination (plug and play).
Other measurands can be derived from the measured values determined. Up to four measured values
are recorded. They are transmitted to the receiver of the Wtrans measuring system at a radio frequency
of 868.4 MHz and displayed there. They are available as digital or analog output variables. The voltage
is supplied externally (DC 18 to 30 V) or internally by means of four lithium batteries (size AA). The bat-
tery operating life with the recommended type of battery is one year (with default settings and one sen-
sor).
The electronics of the measuring probe with backlit LCD display and operating keys are encased in a
wall-mounted case (protection type IP65). The ambient temperature range of the measuring probe is
-30 to +80 °C, but the differing ambient temperatures of the sensors and lithium batteries must also be
considered. The measuring probe can be configured using the USB interface or the operating keys.

, or RTD tempera-
ture probe Pt1000
(2) Connection for USB connector (Mini-B): if the interface is not needed or after a configuration, the
opening on the device must be sealed using the sealing screw M12 × 1.5 supplied (accessories
set) with the help of the mounting key (accessories set).
(3) Connection for external voltage supply: if the voltage is supplied externally, the cable fitting sup-
plied (accessories set) must be used instead of the M12 × 1.5 sealing screw. Install the cable fit-
ting instead of the sealing screw labeled with (3).
