Controller
Piezoconcept controllers include ultra low noise and highly linear electronics, closed-loop control (PID) creating a movement free of positioning errors.
Our controllers offer three different ways of control that can be used simultaneously
Voltage control: an analogue input (BNC) located on the front panel of the controller allows to control the position of the stage by using voltage. Different ranges are possible : (0-10V, -5V/+5V, or -10V/+10V).
USB interface (optional) allowing control of the stage’s position by using a computer.
The USB connector is located on the front panel of the 1-axis controller or on the back panel of the 2/3 axis controller. It comes with 4 TTL outputs ( that can be configured also as inputs)
10-turns manual potentiometer (optional) located on the front panel.
Every stage comes with the appropriate controller which is included in the price displayed on your site.
