High-Precision CAN Bus Non-Contact Angle Sensor
Introduction
ER-AS-25 adopts the combination of embedded microprocessor and numerical control angle second-level calibration device, and adopts program calibration conversion to realize the characteristics of high precision, low temperature drift and low power consumption. Achieve CAN bus protocol, 100HZ output frequency, high resolution 0.015°, full range accuracy 0.05°.
The angle sensor uses MEMS technology to integrate the nano magnetic cluster thin film material and the differential array magnetic sensor element to produce a non-contact induction rotating magnetic field change. The system integrates a microcomputer, voltage and current transmitters and various circuit protections. Programmable intelligent control is set by DSP processing, linearity correction, temperature compensation, output signal standardization according to range, digital filtering, zero setting and multi-level different slopes.
The product has the characteristics of non-contact, long life, high resolution, low temperature drift, good linearity, fine reset, high frequency response, multiple protections, anti-interference, anti-vibration, and anti-shock characteristics, that is suitable for water, oil, gas, vibration, shock, especially harsh industrial environments, are also ideal alternatives to contact angle sensors (such as conductive plastic potentiometers).
