What aspect of the smart pressure sensor defines whether a trigger acts as a NO or NC contact?

The aspect of the smart pressure sensor that defines whether a trigger acts as a normally open (NO) or normally closed (NC) contact is polarity. In the context of sensors, polarity refers to the direction of the electrical signal or the way the circuits are connected.

When dealing with switches and contact configurations, the wiring and the polarity can determine how a sensor responds to pressure changes. In a normally open setup, the circuit remains open until the sensor detects a certain condition (like pressure), while a normally closed setup means that the circuit is closed until the condition is met. If the sensor is designed such that it changes the polarity when activated, it will result in a transition from NO to NC or vice versa.

Understanding this relationship is crucial for correctly implementing control systems based on sensor data. Knowing how polarity affects the behavior of the sensor helps engineers and technicians design appropriate systems for triggering actions in response to specific measured conditions, ultimately leading to better automation and control in industrial environments.
