The HW228B angle sensor combines an embedded microprocessor with a CNC angle second-level calibration device, enabling programmed calibration and conversion, achieving 4-20mA (0-20mA) and 0.1º high precision measurement.
The magnetic angle sensor features contactless operation, long lifespan, high resolution, low temperature drift, excellent linearity, precise reset, high frequency response, multiple protections, anti-interference, vibration and impact resistance, making it an ideal angle sensor for various harsh industrial environments such as water, oil, gas, vibration, and shock. It is also a product that updates traditional contact angle sensors (such as conductive plastic potentiometers).
Main Features
● Sampling rate 1K HZ ● Full range accuracy 0.1° ● Output 4~20mA, 0~20mA optional ● Wide voltage input DC 9～36V
