It is typically installed in areas where it is not feasible to monitor or secure the location effectively by other means. This includes areas like server rooms, vaults, safes, and other critical areas that may contain confidential or valuable items.
There are different types of tamper switches available in the market. However, all of them work in the same principle of detecting unwanted access or tampering. Some common types of tamper switches include:
- Gravity switch: It is a simple switch that is triggered when it detects any tilt or movement beyond a certain angle.
- Vibration switch: This switch is triggered when it detects any vibration or movement. It is commonly used in glass break detectors and other applications where a sudden increase in vibration is a sign of tampering.
- Pressure switch: It is triggered when it detects a change in pressure or force. For example, it can be installed in a door or window frame to detect any attempt to pry it open.
- Magnetic switch: It is triggered when the magnetic field around it changes. It is commonly used in door and window alarms.
Definition of Flow Switch
A flow switch is a device that monitors the flow of a liquid or gas through a pipe or duct. It detects the flow of fluid and sends a signal to a control system to alert it to changes in flow rate. Flow switches are used in a wide range of applications, from heating and cooling systems to chemical processing plants, to ensure that a consistent flow of fluid is maintained.
- Flow switches can operate on a variety of principles, including paddle, thermal, and magnetic. Paddle switches use a spring-loaded paddle that moves in response to changes in flow rate, thermal switches use a bimetallic strip that changes shape with temperature, and magnetic switches use a magnetically actuated switch to detect changes in flow.
- Flow switches can be normally open or normally closed, meaning that they either close or open a circuit when the flow rate exceeds a certain threshold.
- Flow switches can also be adjustable, allowing the user to set a specific flow rate to trigger the switch.
When a flow switch detects a change in flow, it sends a signal to a control system that can trigger alarms, shut off pumps or fans, activate backup systems, or take other actions to maintain safe and efficient operation.
