Introduction

Current Type Non-Contact Angle Sensor

Introduction
ER-AS-18 magnetic angle sensor adopts MEMS technology and is processed by DSP. It can control linear correction, temperature compensation, output signal standardization, digital filtering, zeroing, multi-level different slope settings and programmable intelligent control according to the range to achieve 0~360°. The current output position is measured in the range of 360°, and the user can set the angle from 4 to 20mA.
The sensor uses 9V~36V power supply, has reverse and anti-pulse peak voltage protection functions, and the measurement error is ±0.3°, and the absolute temperature drift is ±20~50A.
