MODEL SL20-8 & SL29-115 TILT SWITCH PROBE & CONTROL
The Model SL20-8 and SL29-115 Tilt Switch Probe & Control provide simple alarm output for both dry bulk materials or liquids when used with a float ball accessory. The rugged non-mercury probe is suspended vertically over a material pile, bin or conveyor belt and as the material level rises to tilt the switch approximately 15° from vertical in any direction, an alarm output signal is activated. The control unit is designed with an adjustable time delay to prevent false trips from vibration, wind or accidental movement. Various attachment accessories are available for the probe, such as wear paddles and float balls.
