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.

  5. Force Sensors and Load Cells
    - 2 Suppliers 22 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
    - 2 Suppliers 3 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
    - 3 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
    - 3 Suppliers 13 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.
