LCA318T/LCA328T MEMS Tilt Sensor High-Accuracy 4–20mA Inclinometer for Industrial Angle Measurement
PRODUCT DESCRIPTION
LCA318T / LCA328T series tilt angle is a small-volume MEMS uniaxial tilt sensor developed by RION. The output current is internally quadratic linearity corrected. It is a linearity current output tilt angle sensor. It is mainly aimed at applications where volume and cost are highly restrictive. Due to the built-in inclination unit of the latest micro-electromechanical production process, the product is small, long-distance transmission can reach more than 2000 meters, and it has strong resistance to external electromagnetic interference and can be adapted to long-term work in harsh industrial environments.
This product adopts the non-contact measurement, which can output the current attitude and inclination in real time. It is simple to use and does not need to retrieve the relative changes. It is an ideal choice for industrial automation control and platform measurement attitude!
This product is mainly used for static and dynamic angle measurement with slow change, and has strong ability to resist external electromagnetic interference, and can adapt to long-term work in harsh industrial environment.

KEY WORDS
Resolution: It refers to the smallest change value that the sensor can detect and distinguish in the measurement range.
Measure accuracy: Refers to the combined error of linearity, repeatability, hysteresis, zero deviation, and horizontal axis error of the sensor under normal temperature conditions.
Long-term stability: refers to the deviation between the maximum value and the minimum value of the sensor under normal temperature conditions after a year of long-term work.
Response time: It refers to the time required for the sensor output to reach the standard value when the sensor changes angle once.
INSTALLATION DIRECTION
During installation, keep the sensor mounting surface parallel to the target surface to be measured, and reduce the impact of dynamics and acceleration on the sensor. This product can be installed horizontally or vertically, please refer to the following diagram for the installation method:
