INTERCHANGEABILITY
In order to obtain an accurate and better temperature compensated response, each sensor is
submitted to a characterization process and the specific data is stored in an EEPROM located in the
sensor body.
The main board, in this operation, reads the sensor serial number and compares it with the number
stored in the main board. In case they do not match, the circuit considers that the sensor has been
changed and will probe the memory of the new sensor for the following information:
Temperature compensation coefficients.
Sensor trim data, including 5-point characterization curve.
Sensor characteristics: type, range, diaphragm material and fill fluid.
Information not transferred during sensor replacement will remain unchanged in the main board
memory. Thus, information such as Upper Value, Lower Value, Damping, Pressure Unit and
replaceable transmitter parts (Flange, O-ring, etc.) shall be updated, depending whether the correct
information is that of the sensor or the main board. In the case of a new sensor, the main board will
have the most updated information; in the opposite case, the sensor will have the correct information.
Depending on the situation, the updating shall be from one or the other.
Data transference from the main board to the sensor or vice versa, can also be forced by function
MAINT/BACKUP/READ FROM SENSOR.
RETURNING MATERIALS
Should it become necessary to return the transmitter and/or configurator to SMAR , simply contact our
office, informing the defective instrument's serial number, and return it to our factory.
In order to speed up analysis and solution of the problem, the defective item should be returned with
a description of the failure observed, with as much details as possible. Other information concerning
the instrument operation, such as service and process conditions, is also helpful.
