The Zerotronic measurement sensor is so far the only one that can complete quasi-dynamic or static high-precision measurement tasks in a variety of environmental conditions (different temperature, humidity, vacuum). Quasi-dynamic measurement refers to the measurement of Angle or inclination of unstable objects or objects moving at low speed. High precision, high resolution and high sensitivity are the outstanding qualities of the new generation of Zerotronic digital sensor. The sensor has solid structure and compact design, with built-in measuring unit and RS485 interface, sampling and transmission integration; The sensor core unit and the sensor housing are all manufactured and debutted in the non-magnetic area. The sensor adopts digital technology, which can meet the long-distance wired transmission without signal attenuation. At the same time with bluetooth technology to achieve wireless transmission.
