LCA341A Industrial Tilt Switch with Relay Output for Crane Safety
GENERAL DESCRIPTION
LCA341A series a low cost tilt switch developed for application like level safety alarming and platform level monitor and alarm. There is relay output circuit inside. Alarm threshold value is pre-stable. when the inclination exceed set alarm value, it will output relay output signal(drive current 1A) to drive the solenoid valve hydraulic system or drive buzzer or alarming light for the safety of platform. Its main function is to monitor and alarm the(dual axis or single axis) inclination of platform automatically. It is well-designed, the temperature and linearity are compensated. It has short-circuit, high voltage, surge protection etc. And all its components meet the requirement of industry application.

MEASURE DIRECTIONS&FIX
The installation must guarantee the product bottom is parallel to measured face, and reduce the influence of dynamic and acceleration to the sensor. This product can be installed horizontally or mounted vertically (mounted vertically selection is only applicable to the single axis, and only can do relative measurement , if absolute measurement the level reference will occur error ), for installation please refer to the following scheme.
PRODUCTION INSTALLATION NOTES
Please follow the correct way to install tilt sensor, incorrect installation can cause measurement errors, with particular attention to 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. The sensor axis and the measured axis must be parallel ,the two axes do not produce the angle as much as possible.
