The Latest Information on Piezoelectric Actuators is Available Here
Options and Accessories
Factory Installed Options
The following options must be installed in the piezo translators during the manufacturing process. They must be ordered with the Piezo and cannot be added later. If necessary contact your local PI office for details on how to order modified translators. P-177.10 Strain Gage Position Sensor for Piezo Stack Actuators For positioning requiring high repeatability and accuracy the P-177.10 strain gage position sensor is available. (click here for details on Position Sensition and Closed Loop Operation). PZTs with strain gage sensors are equipped with an 1 m PUR cable with LEMO FFA.0S.304.CLAC32 connector in addition to the voltage cable. The P-177.10 option includes factory calibration of any PI servo controller (see "Piezo Control Electronics" section) delivered with the sensor equipped Piezo translator.
Extended Temperature Range
Standard HVPZTs work in the temperature range from -40 °C to 80 °C (-40 °F to +176 °F).
For some applications this range is insufficient.
The following Options are available:
P-702.10 (only for HVPZTs)
High temperature range
-40 °C to +150 °C /
-40 °F to +302 °F /
233 K to 423 K
P-702.20 (only for HVPZTs)
Low temperature range
-273 °C to +80 °C/
-452 °F to +176 °F /
0 K to 353 K
Generally all Piezo ceramics function down to zero degrees Kelvin. However, piezo translators are constructed of a combination of materials (ceramics, metal, insulating materials...) which makes the situation more complex.
To qualify the piezoelectric translators for cryogenic temperatures, special insulation material and cement must be used. The low temperature translators are delivered as bare ceramic stacks without case and mechanical preload. The electrical connection is via two 50 cm Teflon leads without connector.
