Application notes
The PT1000 sensor should be installed set off from the module, in
order to avoid measuring errors by internal heat dissipation of elect-
ronics.
To long sensor connecting cables are to be avoided, because these
can be received into the two conductor resistor measurement and
cause EMV interference coupling.
The calibration at works is done at 8 V. The specied technical data
are valid for this operating voltage. Other congurations and special
calibrations as per customer requirements are also possible.
For connection of probes in longer routes, the I²C-Bus, which is used
outside the device, should not be used internally, to avoid effect of
inter-connection disturbances on internal device communication. The
EMV-guidelines are to be followed; use of shielded lines is recommen-
ded.
Due to short time interruption of operating voltage, a RESET of humidi-
ty probe can be initiated. If the operating voltage is adjustable, then the
pull up resistors of I²C Bus must be connected to the triggering voltage.
For simplifying your product development, a communication board and
also an USB-I²C-adapter is available – please contact us!
