Introduction

Current Type High Precision Contactless Angle Sensor

Introduction
ER-AS-28 angle sensor is embedded with a microprocessor and a secondary numerical control angle calibration device, as well as program calibration and conversion, achieving 4-20mA (0-20mA) output and 0.1 high-precision measurement.
The magnetic sensitive angle sensor 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).
