Sensors

Sensors come in a vast array of types, but essentially all types of sensor share the same characteristic and perform a similar function. Regardless of the type of sensor, or the setting, they are used to detect, record or measure levels, or to sense changes to its environment. The data that is recorded by the sensor is transmitted to its computer and then tells the output device (the actuator) to output in a given way. Sensors are available to measure, record or detect electrical current, temperature, air quality, humidity, movement, flow and light, to name just a few. Fibre optic sensors, as an example, can operate in extreme temperatures and are unaffected by electromagnetic interference. Sensors are widely used in an extensive range of domestic and industrial applications, from everyday settings in the home to extreme conditions.

  1. Current Sensors
    - 11 Suppliers 102 Products

    Current sensors are devices that allow measurements of electrical current in a wire to be recorded. The current sensor produces a signal which is proportional to the current. This can be shown as current, analog voltage or in digital format.

  2. Environmental Sensors
    - 7 Suppliers 721 Products

    Environmental sensors are devices that are used to detect, measure or analyse existence of substances in the environment. Examples include sensors to measure air humidity and temperature, as well as safety devices that can detect harmful gases, such as carbon monoxide. They can be used in domestic and industrial settings.

  3. Fibre Optic Sensors
    - 1 Supplier 1 Product

    Fibre optic sensors are sometimes referred to as fibre optic thermometers. This is because they are typically used to measure and record temperatures, often extreme temperatures. As fibre optic sensors are unaffected by radio frequency interference and electromagnetic interference, they are extremely reliable.

  4. Flow Sensors
    - 12 Suppliers 263 Products

    Flow sensors are devices that can be used to record and measure fluid flow rate. They are suitable for use in a wide variety of environments and settings. Flexible fitting options and variable installation positions make flow sensors versatile and adaptable. Flow sensors can use analog and switching outputs.

  5. Force Sensors and Load Cells
    - 10 Suppliers 173 Products

    Force sensors and load cells, also known as weigh/weight cells and force cells, are transducers that convert the load that is applied into an analog or digital output. The output signal can be electrical, pneumatic or hydraulic. Force sensors and load cells are used extensively in weighing applications.

  6. IC Sensors
    - 7 Suppliers 18 Products

    IC (integrated circuit) sensors, also known as IC temperature sensors are an integrated circuit device with two terminals. A small sensor unit with a fast response time works seamlessly with the transducer that produces output proportional to the absolute temperature.

  7. Light Sensors
    - 5 Suppliers 13 Products

    Light sensors, commonly also referred to as photoelectric sensors, are devices that detect the absence or presence of an object. They can also determine the distance the object is away from the source. Infrared technology works with a photoelectric receiver and converts into an output signal.

  8. Liquid Level Sensors
    - 8 Suppliers 409 Products

    Liquid level sensors are devices used to monitor fluid levels in a variety of environments. Liquid level sensors employ optical monitoring technology, often with highly sensitive and precise photodiode technology. A real benefit of liquid level sensors is that can be isolated from the material they are monitoring and pose no contamination risk.

  9. Magnetic Sensors
    - 3 Suppliers 35 Products

    Magnetic sensors, also known as magnetic field sensors, are able to detect positions without contacting or causing wear and tear in control technology applications. They are small, but have an extremely large range. Magnetic sensors are particularly useful as they can penetrate any non-magnetisable material.

  10. Miscellaneous Sensors
