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!

ELECTRONIC CHARACTERISTICS

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.

WORKING PRINCIPLE

Adopt imported core control unit and apply the principle of capacitive micro- pendulum. Using the principle of earth’s gravity, when the tilting unit tilts, the earth’s gravity will produce a gravitational component on the corresponding pendulum, and the corresponding electric capacity will change. By amplifying and filtering the electric capacity, the inclination angle is obtained after conversion. ANGLE CALCULATION FORMULA
Angle = (output current-zero position current) ÷ angle sensitivity
Angle sensitivity = output current range ÷ angle measurement range Example: LCA318T-30-A1 (± 30 ° measuring range 16mA output current range) Angle sensitivity = 16 ÷ 60 = 0.266666 mA / °

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: Horizantal installation
Horizantal-down installation Vertical-left installation Vertical- right installation

INSTALLATION PRECAUTIONS

Please install the tilt sensor according to the correct method. Improper installation will cause measurement error. Pay attention to the first “surface” and the second “line”:

1. The mounting surface of the sensor and the measured surface must be tight, flat and stable. The unevenness of the mounting surface is easy to cause the angle error of the sensor measurement.
2. The axis of the sensor and the axis to be measured must be parallel, and the angle between the two axes should be avoided as much as possible.
