Improvement Board That Combines An Angle Sensor And A Corridor Sensor

PVL4m from iC-Haus is a newly launched improvement board that mixes an angle sensor and a corridor sensor in the identical module. The PVL4m performs the analysis of each sensors by the 26-bit encoder sign processor iC-TW29 with an built-in EEPROM. The event board incorporates a tremendous capacitor which permits for non-disruptive revolution counting by iC-PVL for a number of hours with none exterior provide.

In line with the corporate, the PVL4M is the primary business board able to evaluating a TMR angle sensor together with the Corridor sensor for absolute angle measurement and revolution counting on the free shaft finish, the so-called end-of-shaft place. A brand new 26-bit encoder sign processor iC-TW29 with an built-in EEPROM permits the analysis of the 2 sensors. The sine/cosine indicators from the TMR sensor are processed within the chip, interpolated, after which output with an arbitrarily selectable single flip decision, e. g. by way of BiSS interface with an angular decision of 18 bits and 24 bits revolution

 The information output from the shaft angle comes with a small delay of just one.5 μs, which is corresponding to the delays current within the optical encoders, making it quick a exact. Moreover, the automated correction of dynamic sign errors ensures excessive measurement accuracy over temperature or with the axial backlash of the motor shaft. The excessive sign high quality of the TMR sensor permits higher repeatable angle measurements with low hysteresis. Place output by way of SPI or as incremental quadrature indicators with an index at any arbitrary FlexCount decision from 1 to 32,768 pulses can be attainable.
