Pt1000 transducer module with
standard signal output
Drawing - Module
Drawing - Module with plug
Connection of sensors
The Pt1000 sensor element is soldered at the two upper pins as
shown above. The other pins are not allowed to be connected or short
circuited. The connection must be done very carefully because of the
very small pin spacing. Any type of Pt1000 sensors like thin lm chip
resistances, wire wound sensors or even MIMS resistance thermo-
meters can be used as long as the resistance characteristics are as
per DIN/IEC 60751. The connection lead to the sensor should be as
short as possible, in order to avoid measuring error due to distortion
in resistance characteristics.
Note: The sensor element is not in scope of supply (please include
separately with order).
Calibration
The measuring probes are calibrated at works with reference to
Pt1000 resistance characteristics (DIN/IEC 60751), hence full inter-
changeability of the sensor element is guaranteed corresponding to
the accuracy class. Because of the high quality platinum resistance,
the probes are long term stable and maintenance free. Hence, a re-
calibration is not required.
Guarantee
On our high quality measuring products, you get a guarantee of 24
months.
Mechanically damaged sensors or tampering into electronics makes
the sensors devoid of guarantee claims. Calibration services are not
covered in the guarantee.
Connection
Important hint: The four pole pin strip available on the module
is for calibration of the ASIC and hence shall not be connected!
Similarly, the OWI-connection of 20 mA module also should not
be connected to any wire!
The connection of the module (type –10V/20MA) can be identied as
per the picture in the next page. Wrong connection can lead to failure
of the module!
The connection of the module is done at the lateral soldering surfaces
and pads as per the sketch. The dimensions and contact layout also
enables direct soldering of industrial plugs as per DIN 43650. On
demand, the module can be assembled into a housing or provided in
moulded form. Suitable housings are also available on enquiry.
The model with voltage output requires operating voltage. In order
to avoid measuring error in the 0...10 V model due to line resistance
and current ow through the grounding wire, a separate grounding
wire is to be employed for the signal voltage (four pin connection, see
sketch).
The model with current output is supplied by the loop current and
hence it is connected with two pin system. The pin SHIELD is optional
and can be used in application with shielded connection cable for
connecting to the shielding.
