ExPro-C... Temperature/humidity sensors (°C, %rH)
1 / 4
The ExCos-D... transducer generation from together with direct coupled
ExPro-C... sensors are a revolution for measuring temperature and/or
humidity in HVAC systems, in chemical, pharmaceutical, industrial and
Offshore-/Onshore plants, for use in hazardous areas zone 1, 2 (gas)
and zone 21, 22 (dust).
Highest protection class (ATEX) and IP66 protection, small dimension,
universal functions and technical data guarantee safe operation even
under difficult environmental conditions.
The measuring ranges are scalable within the maxium ranges. The
analogue output signal is either 0...10 VDC or (0)4...20 mAand can be
selected on site. The integrated display is for actual value indication
which can be switched off.
All sensors are programmable on site without any additional tools.
ExCos-D-A transducer are additionally equipped with a (0)4…20 mAIS
(IS = intrinsically safe) output, e.g. for an external indicator.

The default/ delievery setup is 0000. In this configuration the password input is not
activated. To activate a password, go to menu point 20, change the 4 digits into your
choosen numbers (e.g. 1234) and press Enter.
Please keep your password in mind for next parameter change!
Due to a new parameter setup the password is requested.
Before starting parametrisation of ExCos-D... transducer an ExPro-C... sensor must be
connected. ExPro-C... sensors are available as ExPro-CT... for single temperature measure-
ment, as ExPro-CF... for single humidity measurement and as ExPro-CTF... for combined
measurement of temperature and humidity. All types are connectable to an ExCos transducer
but only one sensor to one transducer. In acc. with the sensor type you need to set parameter
for one or two measuring ranges.

Important information for installation and operation
A. Installation, commissioning, maintenance
The cable has to be drawn through the cable gland. After electrical connection the
cable gland must be fixed tighten. IP66 must be fulfilled.
In acc. with operation ExCos sensors are maintenance free. Nevertheless maintenance
must comply with regional standards, rules and regulations.
The sensors must not be opened by the customer. For outdoor installation a protective
housing against rain, snow and sun should be applied. For electrical connection use
the internal approved Ex-e junction box.
Attention: Note the explosion proof rules before opening the internal junction box.
Cut off the power supply.
B. ExPro-C... sensors
ExPro-C... sensors are supplied with an instrinsically safe circuit from the ExCos-D...
transducer. Unused connectors must be covered by a protective cap.
C. Long cabling
For using long signal wires, shilded cables are recommended. The shield must be
connected to the ExCos-D transducer inside the terminal box.
D. Separate ground wires
Use for supply and signal wires a separate ground.
ExCos-D... transducer require a 24 VAC/DC power supply.The supply has to be connected at
terminal 1 (–/~) and 2 (+/~), the analogue output at terminal 3 (mA/V) and 4 (GND) for
temperature, at terminal 5 (mA/V) and 4 (GND) for humidity. The electrical wiring must be realized
via integrated Ex-e junction box in acc. to ATEX. Type of protection for the terminals is "Ex-e".
Attention! Before opening the junction box cover, the supply voltage must be shut off!
The optional analogue output at ExCos-D-A is intrinsically safe. Note the maximum connection
values of intrinsically safe parameters (see table below).
Display and Buttons
To change from operation to parametrisation mode and vice versa, push the enter button
for minimum 3 seconds.
