High-Dynamics PIMag Linear Stage
V-522 • V-524 • V-528
-
Physik Instrumente GmbH & Co. KG
Reference-class linear stage. Linear positioning stages with magnetic direct drives largely dispense with mechanical components in the drivetrain and the drive force acts directly on the motion platform. Together with precision bearings, a high travel accuracy and longer lifetime is achieved. The linear positioning stages are particularly suitable for scanning applications. PIMag® Voice Coil. Voice coil drives consist of 2 essential components: A permanent magnet and a coil, which is located in the air gap of the magnetic field. When current flows through the coil, it moves in the magnetic field of the permanent magnet. The direction of motion depends on the polarity. Thanks to their low weight and friction-free drive principle, voice coil drives are particularly suitable for applications, which require high dynamics and high velocities at limited travel ranges. High scan frequencies and precision positioning are also possible with these drives, because they are free of the effects of hysteresis.

Absolute Optical Inclinometer
A2T
-
The A2T is a single axis, digital gravity angle sensor. The A2T serves as a full 360 range absolute tilt sensing programmable level with either digital or analog output. Internally, a rotary bar coded disk is mounted to a weighted gravity driven wheel. A micro-controller strobes an LED to transfer the bar code image onto an optical linear array, then decodes the position every 2 mSec. Magnetic damping provides fast response and settling time while virtually eliminating overshoot and oscillations. An internal EEPROM stores field programmable parameters such as resolution, zero position, direction swap, and mode. This second generation design virtually eliminates the primary accuracy limitation of first generation inclinometers, which is sitation (hysteresis).

Transformer Performance Tester
6691
-
applying ±90V voltage on the winding of the transformer demagnetized and get the voltage value on the terminal and the current value in the winding to draw the hysteresis characteristic curve. This method can be used for linear quantitative analysis of residual magnetism in transformers, and fast demagnetization can be achieved by tracking hysteresis curves. The analyzer can measure magnetism residual rate before and after demagnetization.

Digital I/O Board
3512
Digital I/O Module
The 3512 is an eight channel non-isolated digital I/O board with +5V tolerant 74LCX14 inputs with hysteresis and +3.3V CMOS 74LVTH125 driven outputs. Each I/O line features a series 10 ohm damping and protection resistor and a 4.7K pull up resistor to +3.3V. On power up the outputs are tri-stated, and can then be enabled on a bit by bit basis. Output high drive is 32mA @ 2.0V minimum. Output low drive is 32mA @ 0.8V maximum.
