Company Information:
Encoder
May 21, 2021 | Feedback is often used in the systems in applications all over the world to control speed and/or position, it has been an important role in keeping equipment operating smoothly and accurately. Feedback can be obtained by many different devices, encoder is one of them.
Electronic Components
May 21, 2021 | Electronic components are the elements of circuit which helps in its functioning. They can be classified into two types: Active Components and Passive Components. Active components can process gain. They can give energy to the circuit. On the contrary passive elements do not possess gain and they cannot give energy continuously to the circuit.
Passive components cannot amplify or energize the energy of the signal associated with them, they can only attenuate it, while active components can energize or amplify the signal.
Directional Valve
May 21, 2021 | When putting up an HVAC system, it usually requires a precise amount of constant flow for it to properly size piping, pumps, and other necessary accessories. IF the flow control valves are placed improperly, there will be fluctuations in the pressure systems. Thus, to avoid this from happening, a suitable valve should be installed.
What is DC/DC converter
May 20, 2021 | People often used direct current as a means to charge batteries and their electronic devices. They also use DC power for third rail power systems and railway propulsion. While DC means direct current, it also means constant polarity. Some types of DC will have variances in their voltage, while most will not. A good example of varying voltage would be fluctuating voice signals on a power line. One should never try to reverse the polarity in a DC device, unless it features a diode bridge that will allow for the switch. Most of the battery-powered devices that people use do not have this bridge, so trying to alter the polarity would actually destroy the device.
Damper Actuator
May 20, 2021 | It is sometimes called a damper motor, damper operator, and motor pack. The appropriate name, however, is damper actuator, and solid working knowledge of its correct application can be the key to commercial HVAC system operation and troubleshooting.
Incorrectly installed or broken damper actuators can cause ductwork dampers to open only partially or not at all. This, in turn, and possible IAQ problems.
That's why it's important to specify or install the correct actuators in the first place, or look to them as a possible problem source when troubleshooting commercial systems, according to Mike Wolf, a sales manager for Greenheck, Schofield, Wis. The company makes and markets fans, dampers, and other air-moving products.
Choosing and installing the correct damper in the first place means winning more than half the battle.
Current Transformer
May 20, 2021 | There are more to power system than meets the eye. In fact, we cannot actually see electricity, but we can see how it works (or doesn't work). So many elements come together like a puzzle to form electrical power, one of those being a current transformer.
Contactors
May 20, 2021 | Turning large electrical power loads such as motors, lighting and heaters on and off is a common automation requirement. Applications are found in commercial buildings, industrial equipment and vehicles. The fundamental device for switching electrical power is called a contactor. Contactors are basically beefed-up relays, but with some specialized features for handling high power loads.
The Basic of Circuit Breaker
May 20, 2021 | Electricity is very essential for any home particularly since every type of modern appliance requires electric power to run efficiently. However, electricity can also be very dangerous when the electrical system malfunction. This could cause fire which may leads to personnel or economical damage. Thus, having a safety feature in the electrical system installed is very important.
Calibration Instrument
May 19, 2021 | Calibration is the process of configuring an instrument to provide a result for a sample within an acceptable range. This process eliminated or minimized factors that cause inaccurate measurements.
Although the exact procedure may vary from product to product, the calibration process generally involves using calibration instrument to test samples of one or more known values called "calibrators". The results are then used to establish a relationship between the measurement technique used by the instrument and the known values. The process in essence "teaches" the instrument to produce results that are more accurate than those that occur otherwise. The instrument can then provide more accurate results when samples of unknown values are tested in the normal usage of the product.
Boiler & Burner Control
May 19, 2021 | Burner are devices used to mix oxygen with fuel to achieve controlled combustion. The burner produces a specific flame heat-release pattern that can be controlled within the combustion chamber, making it ideal for heating, melting, manufacturing and steam production, among other things.
Improper control of the burner could potentially cause significant personnel, environmental and economical damage. Thus, proper control with appropriate tools are important for the reason of safety, pollution control and efficiency of operation.
Position Transmitter
May 19, 2021 | Position Sensors/Transmitter detect the position of something which means that they are referenced either to or from some fixed point or position. These types of sensors provide a "positional" feedback.
Analytical Instrument
May 19, 2021 | Analytical Instrument are a large class of instrument used for analytical applications in chemical, pharmaceutical, clinical, food-processing laboratories, oil refineries and many other field. The instruments help in analyzing materials and establishing the composition.
The Basic of Actuator, Type and Source of Energy
May 19, 2021 | Living in the modern world, we never have a day without utilizing or or encountering an actuator. Actuator is a device that makes something move or operate. Actuator can make something move in two motion, linear motion and rotary motion.
