High accuracy inclinometer sensor has 4-20mA current output, ±10°~±180° measuring ranges and horizontal or vertical installation for selection. It is a single-axis/2-axis tilt sensor, suitable for bad industrial working conditions.
Features
- The inclinometer sensor outputs 4-20mA standard current, transmission distance is up to 2000 meters.
- Output signal of the single/dual axis inclinometer has strong anti-interference, which is dedicated to engineering machinery and equipment working in harsh environments.
- The tilt sensor adopts MEMS sensing production process to make precise compensation and correction for temperature error and nonlinear error. Small range accuracy can reach 0.05°, high precision, small size, high packaging technology, strong shock and vibration ability.
- Inclinometer sensor has built-in anti-radio frequency and adopts anti-electromagnetic interference circuit, which is especially suitable for underground non-excavation machinery and other harsh industrial environments.
- In terms of reliability and stability of the industrial inclinometer sensor, it uses industrial-grade MCUs, 3-proof PCB boards, cables, wide-temperature shielded metal casings and other measures to improve its industrial grade.

Inclinometer Sensor Installation Direction Diagram
The installation must guarantee the inclinometer sensor bottom is parallel to measured face,and reduce the influence of dynamic and acceleration to the tilt sensor. This inclinometer sensor can be installed horizontally or mounted vertically, for installation please refer to the following scheme.
Tips: Definitions of inclinometer sensor key specifications.
- Resolution: It refers to the smallest change value of the measured value that can be detected and distinguished by the inclinometer sensor within the measurement range.
- Absolute accuracy: refers to the combined error of absolute linearity, repeatability, hysteresis, zero point deviation, and horizontal axis error of the inclinometer sensor, under normal temperature conditions.
- Long-term stability: It refers to the deviation between the maximum value and the minimum value of the inclinometer sensor after one year of long-term work, under normal temperature conditions.
- Response time: It refers to the time required for the sensor to output and reach the standard value when the angle of the inclinometer sensor changes once.
