SCA141/SCA142 Digital Tilt Switch with Relay Output for Platform Leveling and Safety Alarm
PRODUCT DESCRIPTION
SCA141&SCA142 are digital tilt switches developed for industry applications related to horizontal safety alarm and platform leveling detection, and based on level security alarm and platform leveling detection related industries application, built-in relay output circuit. Users can set alarm angle value by themselves, it will output a no contact relay signals (drive current 1A) when exceeds the safety angle value, Open the electronic valve to control the corresponding hydraulic leg leveling. This product with design precision, again to compensate the temperature and linearity, integrated short-circuit, high-voltage transient, polarity and surge etc. full protection functions, suitable for a variety of harsh industrial environments operating. Using the industrial grade MCU, three-anti PCB, import cable, wide temperature metal enclosure and other measures etc. to improve the industry level on products reliability and stability.

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":
- 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.
- The sensor axis and the measured axis must be parallel, the two axes do not produce the angle as much as possible.
MEASURING 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.
