Which sensor is designed to measure weight load over a defined area?

• A. Stress sensor
• B. Acoustic glass break detector
• C. Interface device
• D. Cross zoning

Answer: (A)

This item tests how weight distribution over a defined area is measured with a sensor. A stress sensor is the type designed to quantify weight load across a sensing surface by detecting pressure or force per unit area. When weight sits on the sensor, the contact area experiences pressure, and the sensor converts that pressure into an electrical signal proportional to the load. This makes it suitable for applications like floor load monitoring, seating mats, or any setup where you need to know how weight is distributed over a defined area. The other options don’t fit this purpose: an acoustic glass break detector listens for the sound of breaking glass rather than detecting weight. An interface device is used to connect different systems or devices, not to sense physical load. Cross zoning is a security concept about dividing a space into zones to manage alarms, not about measuring weight.
