What is a rotary pump?  Essentially a circulating pump will continuously transfer hot water in the loop while it is running. It simply takes water and discharges it at high pressure to the required points, and returns it to the line system for proper circulation. A pump has inlet and outlet openings. Both of these are in the same line with each other.  

What are the types of submersible pumps?  Types of submersible pumps is Deep well pump  Bottom suction pump  Stainless steel pump  Oil filled pump  Submersible utility pumps  Water cooler pump  Mixed and axial flow pumps

What is electric field?  Basically in an atom protons are positively charged and electrons are negatively charged. And each conducting atom has an electric field around it. This is due to the presence of these two factors. It is positively charged while negative charge is withdrawn. So, it can also be defined as the force around an electrically charged particle.

What is a submersible pump? Basically it is a type of centrifugal pump. Instead of pulling water like normal cases, a submersible pump pushes water. It consists of a hermetically sealed motor attached to the pump body which helps in pushing the liquid to the surface. The impeller plates used in this pump are of backward curved type, which helps in pushing the water with great force. Its motor converts rotary motion into kinetic energy, and diffuser blades convert this kinetic energy into pressure energy.

What is magnetic field? A magnet basically has two poles and they are north and south. A magnet either attracts or repels. Also, if the north pole is placed around the south pole, it will attract and if the north pole is placed around the north pole, it will be repelled. The region around the magnet where the poles either attract or repel is called the magnetic field. Basically, in a magnet, the magnetic field is created either naturally as discussed earlier or also by a passing current. When an electric charge moves in space or on a conductor, its motion induces a magnetic field. Therefore, whenever a metallic object such as iron comes within the range of this magnetic field, the magnet will attract the iron towards it.

What is a pilot or air operated valve?  A pilot valve is basically the same as a solenoid valve, however, instead of an electric signal, an air pressure signal will be used to open or close the spool.

What are the benefits of smart sensors? Advantages of smart sensors is  Improve process performance Minimize maintenance by predicting equipment failure Log data for historic records and regulatory compliance Notify of anomalies that affect process quality Self-Test, Self-Calibration and Self-Diagnosis Multi-sensing capabilities High accuracy Improve processing performance

What are the different types of smart sensors?  There are basically five main types of smart sensors used in industrial automation. And they are  Level sensors  Temperature sensors  Pressure sensors  Infrared sensors  Proximity sensors

How Smart Sensors Work? Basically, a smart sensor consists of 5 basic components which are the base sensor, power supply, microprocessor, memory and communication module. A base sensor is a common sensor responsible for detecting physical quantities. A power supply is to supply power to the computing resource and perhaps to the sensor base. A microprocessor is a computing component, which enables the sensor to perform some data calculations in order to measure quantities and take action based on these analyses. Memory is dedicated to storing measured values and calculated data, and also stores the software logic that controls how the sensor handles this data. The communication module is the one that transmits and receives data between sensors and external devices over the same network or the Internet. Essentially a raw base sensor used to provide sensing capability, it is designed to measure physical quantities and produce analog signals. These analog signals need to be processed befor

What is Smart Sensor? Basically, a smart sensor is a device that can measure a physical quantity and give an output related to the measured value just like a normal sensor, but it also has the ability to analyze some data from this measured quantity using built-in computing resources and use this data to take some action to increase the efficiency of the automation process. Use it. And smart sensors can also provide more accurate measurements, thanks to built-in computing resources that filter out any signal noise and convert the measured signal into a usable digital form without the need for transducers like normal sensors. Smart sensors have built-in communication capabilities that enable them to transmit data over the Internet or similar networks and give them the ability to communicate with external devices, which is the main reason why smart sensors are such important components in the Internet of Things.

What is Normal Sensor? Basically a normal sensor is a device capable of sensing physical quantities like temperature, pressure, flow etc. and gives an output correlated to that quantity. And this output can either be an on/off signal, i.e., a switching signal, such as a proximity sensor, or it can be an analog representation of a continuously measured physical quantity, usually in the form of millivolts or some change in resistance value, such as thermocouples or pressure sensors. A common sensor by itself will not be sufficient to be able to use this measured value in an automation system. Instead, a transducer is introduced to enable converting these measured millivolts or resistance into a usable format such as 4 to 20 mA. Then you will need a computing capability like a PLC to use these measured values in some calculations and actions for automation processes.

What is a controller? Basically the controller is used to control the entire process by getting the feedback from the sensors and modulating the actuators accordingly. And the actuators work automatically by receiving commands from the controller. The most popular type of controller is the PLC. 

What is an Actuator? Basically the actuator follows the sensor feedback and let's say you are controlling the process temperature. For example, room temperature should be maintained using chilled water. In this case, an actuator would be a modulating valve to control the flow of cooling water supply. But, real room temperature feedback will be taken by the sensor. Based on the feedback, the valve will open or close accordingly to maintain the process. Includes actuators such as valves, heaters and drives.

What is Quick Exhaust Valve (QEV)?  Essentially, the quick exhaust valve is a three-way valve that operates primarily on the differential pressure between the inlet and outlet ports. And this valve finds application where a fast stroke time is required or where air needs to be exhausted quickly from the cylinder. Quick exhaust valves are widely used in actuators and pneumatic cylinders for quick exhaust and stroking applications.

What are the benefits of HMI? Basically the benefits of HMI are  Enhanced visibility Increased functionality Reduced downtime Enhanced visibility With the ability to display all the important data related to your process in a single dashboard, the HMI gives operators enhanced visibility into their processes at all times. It helps improve productivity. Increased functionality Because the HMI provides real-time data of your process, operators can use this data to monitor production and adjust process parameters in real-time to meet changing demand. Data captured from HMI can be analyzed to help identify areas of improvement for your processes. Reduced downtime With the alarms and alerts provided by the HMI, operators can better monitor their process performance and respond quickly to failures reducing downtime. Also analyzing the data provided by the HMI can help identify areas where future problems may occur and take appropriate action.
