PI's Digital Piezo Controller Now Upgraded to 4 Channels, Quick Delivery Available
This dynamic cost-effective controller is well-suited for multi-axis applications from microscopy to semiconductor metrology.
PI (Physik Instrumente) L.P., an industry leader in precision motion control systems, and nanopositioning solutions, announces a new, 4-channel version of its high-performance E-727 digital piezo controller.
The E-727 is designed for multi-axis nanopositioning applications, such as 3D imaging in super-resolution microscopy, laser beam steering, image stabilization in astronomy, and fast alignment applications such as used in fiber alignment and semiconductor CD testing.
In addition to a broad choice of digital high-speed interfaces, such as SPI, Ethernet, and USB (and traditional RS-232), it also provides 3 additional high-resolution analog inputs.
Ultra-Low Noise Controller, Digital Linearization
Low noise 20-bit DAC & ADC converters provide high resolution and stability. 4 integrated piezo power amplifiers with an output range of -30 to +130V as well as circuitry for capacitive feedback sensors, piezoresistive sensors, and traditional strain gauges are also on board. The digital servo provides PID control with two programmable notch filters for higher bandwidth by suppression of mechanical system resonances. Digital linearization is based on 4th order polynomials for extreme linearity and absolute positioning accuracy. An optional Dynamic Digital Linearization (DDL) firmware eliminates phase lag and dynamic non-linearities at high operating frequencies.
Data Recorder, Auto-Calibration ID Chip, Quick Start UP, Comprehensive Software Package
A data recorder for high speed tracing, ID chip compatibility for quick start-up, and exchange of system components without recalibration are also included. The controller comes with extensive software support for LabVIEW and shared libraries for Windows and Linux.

Featured Product
FLIR Si1-LD - Industrial Acoustic Imaging Camera for Compressed Air Leak Detection
The FLIR Si1-LD is an easy-to-use acoustic imaging camera for locating and quantifying pressurized leaks in compressed air systems. This lightweight, one-handed camera is designed to help maintenance, manufacturing, and engineering professionals identify air leaks faster than with traditional methods. Built with a carefully constructed array of MEMS microphones for high sensitivity, the Si1-LD produces a precise acoustic image that visually displays ultrasonic information, even in loud, industrial environments. The acoustic image is overlaid in real time on a digital image, allowing you to accurately pinpoint the source of the sound, with onboard analytics which quantify the losses being incurred. The Si1-LD features a plugin that enables you to import acoustic images to FLIR Thermal Studio suite for offline editing, analysis, and advanced report creation. Field analysis and reporting can also be done using the FLIR Acoustic Camera Viewer cloud service. Transferring of images can be managed via memory stick or USB data cable. Through a regular maintenance routine, the FLIR Si1-LD can help facilities reduce their environmental impact and save money on utility bills.
