What Are Industrial Sensors?

Industrial sensors are devices used to monitor and measure physical variables such as pressure, temperature, level, flow and more within industrial processes. These sensors play a vital role in ensuring equipment runs safely, efficiently and accurately. making them essential for process control and automation across industries like oil & gas, chemical, food processing, power generation and water treatment.

How Do Industrial Sensors Work?

Industrial sensors operate by detecting changes in physical or chemical conditions and converting those changes into an electrical signal that can be interpreted by a control system, display, or transmitter. The exact working principle depends on the type of sensor:

  • Pressure Sensors detect force exerted by liquids or gases and convert it into an electrical signal using strain gauges or piezoelectric elements.
  • Temperature Sensors (like RTDs and thermocouples) measure heat levels based on resistance or voltage changes in a metal wire.
  • Level Sensors use technologies such as radar, ultrasonic waves, or capacitive sensing to determine the level of solids or liquids in a tank or silo.
  • Flow Sensors (like Coriolis or magnetic sensors) measure the movement of fluids and convert flow velocity or mass into an electrical output.
  • Analytical Sensors (e.g., pH or conductivity) measure chemical properties in process fluids.

Once the sensor gathers the data, it sends the information to a transmitter or control system, which processes the signal and takes necessary action, like opening a valve, triggering an alarm, or logging the data for quality control.

At The Transmitter Shop, we understand how vital accurate sensing is to industries like oil & gas, chemical, food processing and water treatment. That’s why we offer only trusted, field-proven products that meet or exceed OEM performance standards.
