Signal Generator - DDS Function Signal Generator Wave 2MHz

Today we would like to introduce you the signal generator. Signal generators, also known as function generators, RF and microwave signal generators, pitch generators, arbitrary waveform generators, digital pattern generators or frequency generators are electronic devices that generate repeating or non-repeating electronic signals (in either the analog or digital domains). They are generally used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices; though they often have artistic uses as well.

The signal generator we introduce today is a full DDS signal source. With the use of DC 5V power supply, it can output sine wave, square wave (1% -99% duty cycle can be adjusted), triangle, and sawtooth waveforms. The maximum output of the Signal Generator is up to 10Vpp, and the frequency is from 0.01Hz to 2MHz. It has a resolution of 10mHz, and has both TTL sync output and 60MHz frequency counter with three kinds of functions in one.

UDB1100 series is the upgrade of the original SG1000 series to increase the beautiful plastic case. Upgrade to the BNC input connector output interface, while increasing the output attenuation switch (-32dB, about 40 times), can makes this instrument a minimum capacity of about 10mV output signal. It’s the ideal equipment of electronic engineer, laboratory, production lines, the teaching and scientific research.

K-3 Spray Gun - Car Spraying Sprayer Air Brush Paint

Today we will introduce you an product called K-3 Air Spray Guns. Firstly, let me tell you what air spray gun is. Air spray gun is an tool that uses compressed air to make the paint drops atomized into tiny and then be driven by the airflow onto the surfaces of the object that is been painted. It was consist of shower nozzle, nozzle and needle valve.

      

It can be divided into Smoke type spray gun, Gravity gun, and Pressure painting type spray gun. The first two type are siphon for paint. Air flow produces low pressure in the nozzle surface, and absorb the paint to the suction nozzle and make the paint drops atomized into tiny spray. Paint pot of Smoke type spray gun is under the nozzle and Paint pot of Gravity gun is above the nozzle. air spray guns are widely used in painting and construction industry, it can paint with 5 ~ 10 times higher efficiency than that of brush painting. The paint film is meticulous, smooth, beautiful.

The K-3 spray gun we introduce is with ergonomic gun body design that helps to reduce painter fatigue and adopts advanced die casting processes. It has three adjustment knobs: spray pattern adjustment knob to adjust the area of spraying; fluid control adjustment knob to control the volume of the coating; air pressure adjustment knob to control airflow. Besides that, side mounted gravity cup allowing 360° rotation provides the operator options to spray at a wide variety of angles and helps to achieve high transfer efficiency control and superior atomization. It is compatible with solvent and waterborne coatings (No chemical reaction to aluminum) and commonly used by auto painters, hobbyist and artists for paint chip repairs, signs, backgrounds, murals, etc.

Air pressure regulator is a device used to manage air pressure streaming through systems such as the piping system. It controls the intensity of pressure coming through. It basically reduces to normal pressure, the high intensity of pressure streaming through a piping system. Therefore, in order to regulate the amount of air pressure in various devices where high air pressure can be hazardous. Air pressure regulator is needed to limit the damaging effects of high air pressure(from airpressureregulator.net).

There are certain advantages of using air pressure regulator and we will talk two of them. Firstly, it helps keep the set pressure by regulating the incoming air pressure thereby limiting the damages caused by fluctuating air pressures to various devices. The second is that, newer version of air pressure regulator is made of plastic instead of metal, this helps to prevent corrosion and at the same time, it’s cost effective(from airpressureregulator.net).

Now let’s show you the product in our website – marcmart.com. The air pressure regulator - air filter regulator compressor 1/4 Inch pressure gauge - can discharge water automatically and it has the advantages of stable pressure, high precision, and quick reaction.

Filter and regulator are together as one part, which makes it has compact dimension. Filter adopts novel vane design with high division efficiency and differential pressure discharge device. It can discharge water automatically. Regulator valve adopts balanced inlet structure with the advantages of stable pressure, high precision, and quick reaction. It can help to filter liquid and foreign particles from compressed air line, widely used for pneumatic tool and components.
