Detects the physical force of gases or liquids in a system and turns it into an electrical signal for monitoring and control.

Measures the force exerted by gases or liquids inside a system — helps operators check equipment, find leaks, and keep machines safe.

A dial instrument that measures and displays heat levels at a glance for quick operator checks.

An electronic device that produces and sends out signals — electrical, digital, or otherwise — to convey pressure, level, or flow data from the field to the control room.

A rugged, self-powered temperature sensor made from two dissimilar metal wires joined at one end — a mainstay of industrial temperature measurement.

A resistance temperature detector (RTD) made of platinum, prized for its accuracy and stability in process temperature measurement.

Detects heat or cold and converts it into an electrical signal for the control system — thermocouples and thermistors are common examples.
