Sensors

A sensor can be said to be a form of a transducer that converts energy from one form to another. There are different types of sensors, such as the direct indicating sensor like mercury thermometers that are human readable and other sensors working with an indicator or display. Most sensors are electrical or electronic or wireless sensors, and they are used in automobiles, medicine, industry, robotics, aerospace and machines.

One of the many sensors available today is the motion sensor that has a physical mechanism or electronic sensor. This sensor has the ability to quantify motion that is connected or integrated to other devices. With motion sensors, the user will be alerted when moving objects are within the field of vision. This is the principle used in burglar alarms to alert the owner of a property or security service when any motion is detected.

The humidity sensor is today gaining significance in different fields of measurement and control technology. Humidity sensors and applications have improved in their durability, and they are widely used in different environments. When choosing a humidity sensor, take into consideration its interchangeability, long term stability, size, accuracy, packaging, resistance to chemical, physical contaminants and long term stability.

Wireless torque sensors are found in torque sensing systems and they are used for sending and receiving wireless signals. They are usually found configured on a substrate to be used with antennae so that they can send wireless signals to and from the torque sensor. With a pressure sensor, it is possible to measure pressure of gases and fluids by generating a signal related to the pressure imposed on the substance. Signals here are usually electrical, but they can also be optic, visual and auditory signals.

Oxygen sensors are used to measure the proportion of oxygen found in a gas or liquid that is to be analyzed. The oxygen sensor features a bulb that is coated with zirconium ceramic, which is in turn coated with platinum on both sides. This sensor is available in both heated and unheated forms.

With the help of position sensors, it is possible to get accurate and non-contact position sensing in numerous output configurations and housing styles. The latest range of position sensor uses high resolution digitally based linear feedback which is useful in distributed control architecture.

The MAP sensor is an important sensor used in modern internal combustion engines for fuel injection. Being connected to the intake manifold, it helps in measuring the level of manifold vacuum. With this, the electronic control unit of the engine tunes the amount of fuel to be used and also the timing of injections and spark plug ignition. A temperature sensor is used in temperature control systems to detect the temperature and pass the recorded information to the control device.
