Resolution : Refers to the sensor in measuring range to detect and identify the smallest changed
value.
Measurement accuracy: refers to multiple measurements of angle (more than 16 times) under normal
temperature conditions, and the root mean square difference between the measured value and the
actual angle error.

▶ORDER INFORMATION
E.g： HCA518T-10-A1-N： Single / standard horizontal measurement/±10°measure range /4-20mA output.
▶MECHANICAL PARAMETERS
○ Connector: aviation connector
(1m Direct Leading Cable can Be Customized)
○ Protection level: IP67
○ Shell material: aluminum alloy shield oxidation
○ Installation: Three M4 screws
▶WORKING PRINCIPLE
Adopt the import of core control unit, using the capacitive micro pendulum principle and the earth gravity
principle, when the the inclination unit is tilted, the Earth's gravity on the corresponding pendulum will
produce a component of gravity, corresponding to the electric capacity will change,, by enlarge the
amount of electric capacity , filtering and after conversion then get the inclination
▶ANGLE OUTPUT CALCULATION FORMULA
Angle=(output current-Zero position current)÷Angle sensitivity
Angle sensitivity=output current range÷ Angle measuring range
E.g：HCA518T-30-A1-N (±30° measure range 16mA output voltage range )
Angle sensitivity= 16÷60=0.266666 mA/°

▶PRODUCTION INSTALLATION NOTES
Please follow the correct way to install tilt sensor, incorrect installation can cause measurement errors,
with particular attention to the "surface", "line".
1）The Sensor mounting surface and the measured surface must be fixed closely, smoothly, stability,if
mounting surface uneven likely to cause the sensor to measure the angle error.
2) The sensor axis and the measured axis must be parallel ,the two axes do not produce the angle as
much as possible.
