säätöanturin

Säätöanturin is a Finnish term that translates to "control sensor" in English. It refers to any device that measures a physical property of a system and converts it into a signal that can be used by a control system to regulate that property. These sensors are fundamental components in automation and control engineering, enabling systems to monitor and adjust their environment or performance.

The primary function of a säätöanturin is to provide real-time feedback. This feedback allows a control system, such as a programmable logic controller (PLC) or a micro-controller, to compare the current state of a variable (e.g., temperature, pressure, position, flow) with a desired setpoint. Based on this comparison, the control system can then actuate a device, like a valve, motor, or heater, to bring the variable back to the setpoint or maintain it within a desired range.

Säätöanturit are diverse and are designed to measure a wide array of physical parameters. Examples include thermocouples and resistance temperature detectors (RTDs) for temperature, pressure transducers, proximity sensors for detecting the presence or absence of an object, encoders for measuring rotational or linear position, and flow meters for measuring the rate of fluid movement. The output signal from these sensors can be analog (e.g., voltage or current) or digital, depending on the sensor's design and the requirements of the control system. They are indispensable in industries ranging from manufacturing and process control to building automation and automotive systems, ensuring efficiency, safety, and precision.
