SCA128T Single/Dual Axis High Accuracy Inclinometer Long Distance
Transmit Angle
▶ INTRODUCTION
SCA118T/SCA128T is a standard industrial output type single/dual
axis inclinometer with a standard current output of 4-20mA, which
can transmit up to 2000 meters over long distances. The output
signal has strong anti-interference and is professionally applied
to construction machinery equipment working in harsh environments.
The product is produced using the latest MEMS sensor production
process, and the temperature error and nonlinear error are
accurately compensated and corrected. The highest accuracy in a
small range can reach 0.02 ° (for more accuracy indicators, please
refer to the product performance table), high accuracy, Small size,
high packaging technology, good ability to withstand shock and
vibration. The product has built-in anti-RF and
anti-electromagnetic interference circuits, which is especially
suitable for underground trenchless machinery and other harsh
industrial environments. In addition to having better technical
parameters than ordinary products in the market, the product also
uses various measures such as high-end application-level MCUs,
three-proof PCB boards, imported cables, and wide-temperature
shielded metal shells to improve the reliability and stability of
the products. Industrial grade.
