Electrical Charge Sensors

Electrical charge sensors measure electrical charge in electrical components such as electrical relays and electrical sensors. An electrical relay is an electrical component that completes or interrupts a circuit by physically moving electrical contacts. An electrical sensor consists of two main elements: a detector and a platform that communicates with the detector through an active interface. Electrical charge sensors are just one type of electrical sensor. Other electrical sensor types include charged coupled device (CCD) or CCD image sensors, electrical field strength sensors, and electrical capacitance sensors

Electrical charge sensors measure the electric charge contained in subatomic particles in order to determine the charge’s electromagnetic interactions. The electrons have a -1 charge. The protons have an opposite charge of +1. In electrical circuits, these charges are detected by electrical charge sensors. For example, an electrical relay consists of two circuits: an energizing circuit and a contact circuit. These circuits are common to different electrical relays such as a latching relay, electromechanical relay, contact relay, and timing relay. Charged coupled device sensors (CCD sensors) are electrical components or electronic devices that can transform a light pattern into an electric charge pattern which can be detected by an electric charge sensor.

Electrical charge sensors differ in terms of applications and approvals. Some products are used in industrial applications for accelerometers, motion detectors, and strain gauges. Others are used for communication, medical, transportation, safety, and military applications. Specialized electrical charge sensors are used in high-voltage applications and ultra-low voltage applications. In terms of certifications and approvals, electrical charge sensors often adhere to standards from the Institute of Electrical and Electronics Engineers (IEEE). Electrical charge sensor suppliers are located around the world and, depending on their geographic location, may adhere to other standards. For example, products marketed in Europe may bear the CE Mark to indicate compliance with applicable European Union (EU) directives.
