SDA131B is a dynamic tilt switch newly developed by RION’s D & R, the product can be used in the fast moving car construction machinery, compared to static tilt switch can anti acceleration effect, anti vibration effect; it is a single axis tilt switch apply for the level of security alarm and platform application level detection .Users can set alarm angle value by themselves, it will output the switch signal (output voltage = supply voltage) when exceeds the safety angle value, the drive solenoid valve will cut off the hydraulic system, also can drive the buzzer and warning lights, automatically warn the worker to operate safely .The products are mainly used to control a variety of construction machinery or equipment platform leveling, real-time automatic monitoring on platform tilt in four directions left, right , front and back status . 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.
