Description

A tilt switch with dual relay outputs designed primarily for levelling systems.
The switching threshold is adjusted using the pcb mounted rotary switch. If the tilt exceeds the threshold with clockwise tilt, relay 1 will be switched on, and will switch off when the angle returns to zero (or below). Conversely it the tilt exceeds the threshold with counter clockwise tilt, relay 2 will be switched on, and will switch off when  the angle returns to zero (or above).
In this configuration the tilt switch can be used to drive motorised or hydraulic actuators to maintain a system in a level position.
To make installation easy, it can be mounted horizontally or vertically, and there is a switch to set the zero position after installation.
The unit utilises a high precision MEMS sensing element and is available with and without temperature compensation, which improves the accuracy over a wider operating range.
Features:
  •  Single axis levelling controller with dual relay output
  • Adjustable switching threshold from 0.2 to 4.8°
  • ‘ZERO’ button to set zero after installation
  • Small size and low power consumption.
  • No moving parts means no servicing and long life
  •  High precision switching threshold
  •  Mercury free and RoHS compliant
  •  Sealed to IP65 and CE certified
Applications:
  •  Man lift platform levelling
  •  Recreational vehicle auto-levelling
  • Roller shutter door controls
  • Container levelling
  • Can be readily customised to suit most applications
