Endress+Hauser Pressure Sensor FMB53

Prerequisite: The measured variable is in direct proportion to the pressure. The tank can be filled and emptied.

The values entered for 'Empty calib. (028)/Full calib. (031)' and the pressures present at the device must be at least 1% apart.

The value will be rejected, and a warning message displayed, if the values are too close together.

Further limit values are not checked; i.e. the values entered must be appropriate for the sensor and the measuring task so that the measuring device can measure correctly.

Perform 'position adjustment' Page 39.

Select the 'Level' measuring mode via the 'Measuring mode (005)' parameter.

Select a pressure unit via the 'Press. eng. unit (125)' parameter, here 'mbar' for example.

Select the 'in pressure' level mode by means of the 'Level selection (024)' parameter.

Select a level unit by means of the 'Unit before lin (025)' parameter, here 'm' for example.

Warning: Operation must be unlocked. Refer to page 33, 'Locking/unlocking operation'

The device is configured for the 'Pressure' measuring mode as standard.

The pressure applied must be within the nominal pressure limits of the sensor. See information on the nameplate.

Carrying out position adjustment

Press the 'Zero' key for at least 3 s.

Does the LED on the electronic insert light up briefly?

If Yes: Applied pressure for position adjustment has been accepted.

If No: 1) Applied pressure for position adjustment has not been accepted. Observe the input limits.
