Working Principle
The inclinometer operates on a capacitive micro-pendulum principle, where gravity affects the pendulum, altering electric capacity, which is converted to an inclination angle.

Installation Precautions

Ensure the sensor's mounting surface is tight, flat, and stable.
The sensor axis must be parallel to the measured axis.

Communication Protocol
Utilizes MODBUS protocol with specific data frame formats and command words for operations like reading angles, setting zero points, and adjusting communication speed.

RION MODBUS Communication Protocol
Guidelines include data frame timing, broadcast address usage, and command setting procedures for reliable communication.

Reading Angle Data
Modbus Function Code: 03H, involves interpreting data bytes, converting to decimal, subtracting offset, and calculating final angle.

Set Sensor Relative/Absolute Zero
Modbus Function Code: 06H, involves setting relative zero with host command and slave confirmation.

Set Sensor Address
Command involves changing sensor address with host command and slave confirmation.

Set Sensor Baud Rate
Command involves setting baud rate, effective after power cycle. Baud Rate Settings: A0H: 4800, A1H: 9600, A2H: 19200, A3H: 38400, A4: 115200.

SCA116T/SCA126T MODBUS OUTPUT INCLINOMETER ▶ 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. ▶ INSTALLATION...

SCA116T/SCA126T MODBUS OUTPUT INCLINOMETER needs to be set to a different address to achieve separate control and response angles. 2.If the new address is successfully changed, the address code in all subsequent commands and response packets must be replaced with the new address code after the change to be effective, otherwise the sensor will not respond to the command. This command is a power-off save function.

SCA116T/SCA126T MODBUS OUTPUT INCLINOMETER ▶ RION MODBUS COMMUNICATION PROTOCOL Note, please read the following items carefully before use: 1) Because the MODBUS protocol stipulates that between two data frames should be at least more than 3.5 bytes time (for example, at 9600 baud rate, the time is 3.5 × (1/9600) × 11 = 0.004s). But in order to leave enough margin, this sensor increases this time to 10ms, so please leave at least 10ms time interval between each data frame. The host sends the command-10ms idle-the slave responds to the command-10ms idle-the host sends the command ... 2) MODBUS...
