How does a tilt sensor function?

Mercury Switch: The tilt sensor contains a small amount of mercury inside a sealed, conductive enclosure. The enclosure typically has two or more electrical contacts at different positions.

Gravity Effect: When the sensor is stationary and upright, the mercury settles at the bottom of the enclosure, away from the electrical contacts. However, when the sensor is tilted or inclined, gravity causes the mercury to move and make contact with one or more of the electrical contacts.

Electrical Connectivity: The movement of the mercury creates or disrupts electrical connectivity between the contacts, depending on the sensor’s orientation. This change in connectivity can be used to trigger an electrical signal, indicating the tilt or inclination of the sensor.

Output Signal: The output signal from the tilt sensor typically indicates whether the sensor is in a “tilted” or “level” position. This signal can be utilized in various applications, such as controlling equipment, triggering alarms, or providing feedback for leveling systems.

Calibration: Some tilt sensors may require calibration to determine their sensitivity and threshold for triggering the output signal accurately. Calibration ensures that the sensor responds correctly to different degrees of tilt or inclination.
