PZ244E
P54x Nanopositioner
Strain gauge sensors (SGS)
Strain gauge sensors derive the position information from their expansion. They are attached at
a suitable position in the drivetrain, where they measure the displacement of the positioner's
moving part against the base body. This type of position measuring is indirect and requires
contact, because the position of the platform is derived from a measurement on the lever,
guide or piezo stack.
The sensors operate in thermally drift-free full bridge circuitry and therefore ensure optimum
position stability in the nanometer range.

ID Chip (Models with Dsub Connector Only)
An ID chip is located in the D-sub connector of the P-54x. When the P-54x is calibrated at the
factory with digital electronics, the calibration data is saved on the ID chip together with
specific product information. During switch-on, the digital electronics read the data from the
ID chip of the P-54x connected. A P-54x with an ID chip containing calibration data can
therefore be connected to any suitable digital electronics without renewed calibration.
Refer to the manual for the controller for more information on the ID chip.
