0703-0711-99 ±3° Single-Axis Electrolytic Tilt Sensor

This electrolytic tilt sensor (also sometimes called an electronic tilt sensor) gives narrow range measurement up to ±3° with high accuracy of ±0.001° in one axis (single-axis measurement). This means that you’ll need two sensors to read in two axes (with orthogonal mounting, or mounted at a 90° angle). It has an industrial-grade, all-metal, and hermetically sealed sensor design for use in the most extreme environments. This sensor has the highest accuracy metal tilt sensor we offer, but it’s also higher cost than similar 0717 series tilt sensors. But remember, it’s still a lower cost than all of our glass electrolytic sensors.

All of our electrolytic sensors require an electrolytic tilt sensor circuit (also commonly referred to as signal conditioning or a signal conditioner) to provide a tilt angle output. This can be built into your system or you can purchase an electrolytic tilt sensor circuit we’ve designed. Our circuits are optimized for the best performance from our electronic tilt sensors.

To learn more about the principles of electrolytic sensors and how to integrate our sensors into your application, see our Technical Information page. Confused about terminology? The following terms are often used interchangeably, though they have slightly different meanings; tilt sensor, electrolytic tilt sensor, and electronic tilt sensor.
