A Solid State Relay (SSR) is an electronic switching device that serves a similar function to an electromechanical relay. SSRs differ significantly in their design and operation.
SSRs do not have any moving parts such as contacts, armatures, or springs. Instead, they rely on solid-state electronics. When an external voltage (AC or DC) is applied across its control terminals, an SSR can switch on or off. This switching action occurs without any physical movement.
There are many types of object detection photo sensors available on the market. Some of them, such as photoelectric, laser and ultrasonic sensors. Photoelectric sensors use reflected or detected light waves to detect object presence or distance in a wide range of industrial applications
What is a NAMUR proximity sensor? In this article, we introduce the sensors that called NAMUR proximity sensors. We discuss how this NAMUR sensor differs from other proximity sensors, also what are their applications in the various industries.
1.1 Instrumentation Instrumentation & Process control – Instrumentation is the foundation for process control in automation industry. However, it comes in many forms from domestic water heaters and HVAC (Heating Ventilating and Air Conditioning), where the variable temperature is measured and used to control gas, oil, or electricity flow to the water heater, or heating […]
