PCA826T High Accuracy Industrial Tilt Sensor with FFT Vibration Analysis and MODBUS Output
PCA826T PRECISION INCLINOMETER.pdf
▶ INTRODUCTION
PCA826T is a high-performance product developed specially for the high-precision inclination measurement. Before leaving the factory, all products would have full temperature range calibration and compensation, and a two-week long-term stability test ensures compatibility under different working conditions and maintains the best performance indicators during the long-term test cycle. The product integrates the FFT function, which can measure the vibration of 0.1~20Hz, and estimate the vibration frequency of the object to obtain the maximum speed and maximum displacement of the object vibration. Integrate two kinds of output protocols including the industrial standard MODBUS protocol, the supporting computer analysis software can display and record the measurement data in real time. Output interface RS485, RS422, RS232 optional. The non-contact installation makes PCA826T easy to install or
integrate. Strong resistance to external electromagnetic interference, strong anti-shock and vibration ability, widely used in satellite communication system processing vehicles, special vehicles, radar antenna vehicles, etc.

1) Resolution: Refers to the sensor in measuring range to detect and identify the smallest changed value.
2) MAXE: refers to the biggest error of the product within the range and at multiple angle points.
3) RMSE: refers to the root mean square difference between the measured value and the actual angle of the product within the range and for multiple times (more than 16 times).
4) Zero Temperature Drift Coefficient: the change rate of the indication value relative to normal temperature within the rated operating temperature range of the sensor at the zero degree.
5) Sensitivity Temperature Drift Coefficient: The percentage change rate with temperature of the full-scale indication relative to the full-scale indication at room temperature of the sensor in its rated operating temperature range.
