▶ PRODUCT INTRODUCTION LCA316T / LCA326T series products are a new generation of digital small volume MEMS tilt sensor launched by RION Technology. It has a built-in dual-channel earth gravity tilt unit, which can be converted into tilt angle changes by measuring static gravity acceleration. So that the tilt angle of the sensor output relative to the horizontal plane can be measured. Output method RS232, RS485 or TTL. Because it is a built-in MCU control system, which correct the linearity of the sensor output twice, making up the accuracy drop for the analog type because of insufficient correction....

▶ 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. ▶ELECTRICAL CONNECTION Color Function Power negative Power positive Power negative Power positive PCBA electrical connection Color Function

LCA316T/LCA326T DIGITAL INCLINOMETER SHELL SIZE Shell size: L55×W37×H24mm Installation size: L48×W28.6×H4mm ounting screws: 3 M4 screws ▶ 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:

▶ 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. ▶ RION PRODUCT COMMUNICATION PROTOCOL 1. Data frame format:...

Set relative / absolute zero: The current angle can be set to zero degrees for relative measurement, or it can be set back to the absolute factory zero degree and save after power off E.g: 68 05 00 05 00 0A Sensor response reply command E.g.: 68 05 00 85 00 8A Set communication speed E.g.: 68 05 00 0B 03 13 This command is set to take effect after power off and restart, and save function after power off Sensor response reply command E.g.: 68 05 00 8B 00 90 Set sensor output mode Response system: The upper computer needs to read the angle command before the sensor responds 11 / 16 Data field (0byte)...

to the relative angle Automatic output system: After the sensor is powered on, X, Y angles are automatically output, and the output frequency is set as shown in the table on the right. (This function has power off memory) E.g.: 68 05 00 0C 00 11 Sensor response reply command E.g.: 68 05 00 8C 00 91 Set module address command The default address of the sensor is 00, 1.If multiple sensors are connected to a group of buses at the same time, such as RS485, each sensor needs to be set to a different address to achieve separate control and response angles. 2.If the new address is successfully changed,...
