製品概要

The ADMT4000 is a magnetic turn, counter sensor capable of recording turns of an external magnetic field with zero power. The absolute position, including the number of turns, is reported via a serial peripheral interface (SPI). The EVAL-ADMT4000SD1Z evaluation board allows for the evaluation of the ADMT4000 zero power, multiturn sensor by providing a flexible hardware platform with accompanying graphical user interface (GUI). The EVAL-ADMT4000SD1Z features the ADMT4000 in an end of shaft magnet configuration, Figure 1. The evaluation kit is composed of an EVAL-ADMT4000SD1Z and a magnetic stimulus on a printed circuit board (PCB) mount. To operate with the provided GUI, the EVAL-SDP-CS1Z (SDP-S) or EVAL-SDP-CB1Z (SDP-B) is required, interchangeably referred to as the SDP controller board within this user guide.

The EVAL-ADMT4000SD1Z allows a detailed evaluation of the ADMT4000. The GUI demonstrates turn count, angular measurement, diagnostic measurements, system-level calibration, and device configuration. The EVAL-ADMT4000SD1Z is fitted with a coil to enable magnetic reset of the turn-count sensor. Time stamped captured data can be logged to a technical data management streaming (TDMS) file. The TDMS file format allows large data sets to be stored and indexed. Data logs contain the device settings in addition to time stamped data and fault status. The calibration function allows the user to store the detailed results of the calibration using data captured using the GUI or data captured using the measurement system of the user.

The EVAL-ADMT4000SD1Z also provides 2.54 mm headers for power and digital signals that allow the user to evaluate the EVALADMT4000SD1Z with an external microcontroller platform and start the system software development. The PCB is designed so that the sensor board can be broken off of the SDP interface section to provide a smaller form factor. Power supplies can be sourced from either the USB port via the SDP controller board, or an external bench supply.

For full details of the EVAL-ADMT4000SD1Z, see the ADMT4000 data sheet, which must be consulted in conjunction with this user guide, when using the EVAL-ADMT4000SD1Z evaluation board.
