specification and instruction of inclinometer sensor ZCT230M-LBS-BUS-3105 I.Description ZCT230M-LBS-BUS-3105 is 2-axis high accuracy inclinometer sensor with measuring range of +-30°. The response frequency can be adjustable, and baud rate can be adjusted from 2400bps to 38400bps. II. Features Entirely industrial device is adopted, with stable performance. Shockproof and anti-vibration High cost performance Standard M12 male connector III.Technical Data (in room environment @25℃) 3.1. Operation parameter.

3.3. Other parameter. Dimension Remark 1：when the sensor work normally, make sure it is in the allowable range, 24V is introduced. Remark 2：the sensor should be installed horizontally. Remark 3：the smallest angular increment at which a detectable change in output can be measured. Remark 4：The maximum deviation of the output from the absolute input angle. IV. Work principle Sensitive component The sensitive component of the inclinometer is 2-axis accelerometer which adopted the MEMS capacitance measurement technology. Like other accelerometer, the sensitive component is one differential...

The sensitive component is with analog voltage output of DC0.5-4.5Vol, the signal is firstly filtered by the filter circuit, then turn to the 16bits AD converter which is connected with the MCU by SPI. The sensitive component is processed by zero calibration, sensitivity calibration, anti-sine calibration, accuracy calibration and so on, so finally the sensor can be output angle information directly. Acceleration of gravity g is always with a straight down direction. In the same height and same area, the acceleration of gravity of anything is the same. The value of g will be decreased with...

Our sensor is calibrated by the acceleration of gravity in Shanghai (g = 9.794m/sA2) . When the sensor is used on other place and have a high accuracy requirements, the effective of the change of the acceleration should be removed by the following formula: Angle after calibration=arcsin{[sin(measured angle by the sensor) ]*acceleration of gravity in Shanghai/acceleration of gravity on-spot} Eg. If the sensor is used on Moscow, which is with the gravity acceleration of g = 9.816m/sA2, when the sensor is with angle output of 30°, the actual angle is arcsin [(sin30)*9.794/ 9.816)=29.925°....

0x0001 setting the address of the instrument as the eighth byte data, and the total length is 9 bytes. Remark: the 2nd byte 0x00 is broadcast, the 4th byte 0xAF is the command sent by host sensor, the 5th byte is the command frame, the 6th,7th byte 0x00 0x02 is command words. Return frame of the sensor is:

Remark: ** is the address of the sensor, the 1st byte 0xAF of data packet is command from host sensor, the 2ndsensor 0x00 is command frame.

Return frame of the sensor is as follow:(with frame length of 13 bytes) Command frame and the return frame can be referred to command 0x0004.

0x000a set filter constant, packet length is 9 bytes. Return packet length is 9 bytes, which is received by slave sensor. 0x00 represents minus 50 centigrade. Current temperature is minus 50 adding the received value.

Attentions ： The default address of the host sensor is 0xAF；there are also communications among slave sensors.Only the host sensor can modify the slave sensors, and it is not allowed to modify the addresses and other information among slave sensors. During the matching address process of the slave sensors, if it is not the address packet of themselves, you can cut the serial port to stop.So you can save CPU occupied time to process other tasks. After considerable delay, re-open the serial port interrupt. The delay time is the time of sending data,in other words, it is the data length of the...
