Digital Type High Precision Contactless Angle Sensor
Introduction
ER-AS-26 angle sensor is combined with an embedded microprocessor and a numerical control angle secondary calibration device. Program calibration conversion can achieve high accuracy, low temperature drift, and low power consumption. Digital output has RS232, RS485, TTL, MODBUS (optional), reaching high resolution: 0.015°, high precision: 0.05°, output ratio: 100HZ.
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).
