High Accuracy Inclinometer Dual Axis Digital Tilt Sensor ZCT230M-LBS-BUS

I. General Description

ZCT230M-LBS-BUS is a 2-axis high accuracy inclinometer, which is reasearched and produced by Shanghai Zhichuan. RS485 output, including 485 communication protocol and supporting more inclination networking. Measuring range is ±30°, high resolution, adjustable response frequency and baud rate (2400-38400bps).

II. Features

Industrial devices entirely

Stable and reliable performance

Shockproof, anti-seismic

High cost performance

Housing protection: IP68

III. Applications

Construction machinery,construction vehicles

Security control, tilt control

Angle measurement, level adjustment, zero position adjustment

IV. Technical Specification

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: he 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.

Description of the communication commands：

Frame format：

Protocol description：    

1. 0xA1 is starting code, not only the data from sub-computer to host computer but also data from host computer to sub-computer, are coded starting from 0xA1;
2. 0xAF is the reserved address, there is up to one reserved address in the bus. 0×00 is the broadcast address of the host computer. All the sub-instruments will response to the reserved address. The common command used the address is setting the baud rate of bus instruments;
3. Packet length, from this byte(not contain this byte), data byte, cumulative check, to end byte(not contain calculation byte and parity), maximum length is 255 bytes;
4. ①—-sender’s address code, 0xAF means host computer sends. Other HEX means the address of the instruments which send the data(using for communication between two sub-instruments), using sender’s address to fill the byte;
5. ②—-frame type, 0×00 means command frame, 0×01 means data frame;
6. ③—-MSB of the command word;
7. ④—-LSB of the command word;

N: Cumulative check and parity, sum from the address byte behind the packet to the byte before cumulative sum, then the 8 lower bits is the cumulative check.
