Fig. 33 EDT 96 and EDT 101 transducers connection
The EDT 96 pressure transmitter and the EDT 101 temperature transmitter are supplied by the
manufacturer calibrated in whole measurement range. The calibration and correction data are
stored in the transducer´s internal memory when the transmitter is calibrated and the resulting
measured data already included with the corrections is passed to the instrument control unit.
Nevertheless, the device is equipped with the option of
one-point or two-point adjustment
of
the transducer using the supplied SW [42], [43]. This option is protected by the metrology switch
provided by the metrology mark. In the case of a corrector without MID metrological verification or
an electronic data logger, the adjustment is accessible to the user. A description of the corrector
settings via user SW is given in [38].
For more information on EDT 101 and EDT 96 transducers, see [39] and [40].
5.6.6 Connecting External Power Supply
A cable with a minimum cross section of 0.75 mm
2
is required for the external power supply from
the PS-E (PS-E/A) intrinsically safe power supply.
To connect the external power supply to internal modem from the PS-M (PS-M/A) intrinsically
safe power supply, cable with the conductor cross section of at least 1 mm
2
is required. The table
below shows the maximum length of this cable. The PG9 cable gland is designed for the cable. If
both the corrector and the internal modem are powered from external power supply, the only one
4-core cable can be used for the power supply.
