Free Download Electronic Software EZ Schematic 4.0.1 to Make Electronic Schematic Diagram

Robometricschool. - Maybe you have hear about EZ Schematic electronic software application that used to make electronic schematic diagram. Yes with electronic software EZ Schematic you can make electronic schematic diagram easily.

Figure 1. EZ Schematic Application (Image: programasgratisbr)

EZ Schematic has made by industrial electrician for along time more than 20 years that now we can used to many application to make electronic circuit diagram. EZ Schematics is creating and printing professional looking electrical schematics quickly and easily. EZ Schematic Applications, established in a line chart format, providing end users with the ability to quickly and easily transform logical concepts into professionally displayed electrical schematic. 

Using EZ schematic we can use many symbols that provide like as contacts, relays, timers, motors, limit switches, pressure switches, thermal switches, flow switches, push buttons, selector switches, overloads, transformers, fuses, circuit breakers, foot switches and more.

There are several reason why EZ Schematic is better application than CAD application when used to make electronic circuit diagram as like:

  1. Ease of use. There's no other Cad program available that's easier to learn than EZ Schematics.
  2. Every electrical symbol is created in 1/2" scale increments designed to align perfectly with the default snap (also set at 1/2'), thus making precise placement of the symbols a simple procedure.
  3. Only symbols pertinent to typical U.S. electrical schematics are available (approx. 60). Thus, there's no waste of time in pouring over thousands of choices.
  4. When inserting a symbol, smart choice labeling is employed. For example, when inserting a control relay coil, "CR" is automatically attached as the standard beginning label anticipating it to be followed by "1" or "2", etc.
  5. The "Line" control (the most popular device) becomes readily available by simply double-clicking anywhere in the drawing.
  6. Labeling the wire numbers is performed easily and precisely. Just click and type at the location of choice.

Schematic Diagram Flame Sensor UV TRON R2838 Hamamatsu for Fire Extinguisher Robot

Robometricschool. - One of important part of fire extinguisher robot is sensor that can detect fire in certain field. One of sensor that usually used in fire extinguisher robot is flame sensor UV TRON R2838 from Hamamatsu product. With Flame sensor UV TRON R2838 from Hamamatsu you can get quick detection of flame from distance. This sensor is compact UV sensor with high sensitivity and wide directivity, suitable for flame detectors and fire Alarms.

Figure 1. Ultraviolet Sensor from Hamamatsu (image: sheet data hamamatsu)

According Hamamatsu R2838 sheet data we know that from Hamamatsu R2868 is a UV TRON ultraviolet detector that makes use of the photoelectric effect of metal and the gas ultiplication effect. It has a narrow spectral sensitivity of 185 to 260 nm, being completely insensitive to visible light. Unlike semiconductor detectors, it does not require optical visible-cut filters, thus making it easy to use. In spite of its small size, the R2868 has wide angular sensitivity (directivity) and can reliably and quickly detect weak ultraviolet radiations emitted from flame due to use of the metal plate cathode. The R2868 is well suited for use in flame detectors and fire alarms, and also in detection of invisible discharge henomena such as corona discharge of high-voltage transmission lines.

How to Measure F-STOP in LightMeter

Robometricschool. - Do you know Lightmeter? According the name of this this device, that lightmeter meter is instrument that used to measure light. Usually lightmeter is used in camera to measure light environment and   to make good setting exposure in camera.

Figure 1. Kind of Lightmeter Shape (image:detikinet)

According Enche Tjin that active in digital photography said that there are two kinds of lightmeter these are Reflected Lightmeter and Incident Lightmeter. Here are description of two lightmeter.

Reflected Lightmeter is light measurement system contained inside the camera, and can also be activated in an external lightmeter. Lightmeter will calculate the light reflected by the subject and choose a camera exposure settings (aperture, shutter speed and ISO) to tonalnya 18% gray.

Incident Lightmeter can used to calculate the light falling on your subject. With mode incident lightmeter more accurate because it directly measures the quantity of light falling on your subject, not reflected. Type of incident lightmeter good for portrait photos with a flash, to measure the difference in light exposure of primary (main) and filler (fill).

How to use Reflected Lightmeter and Incident Lightmeter?

When you use Reflected Lightmeter in camera firstly you must active reflected lightmeter with simply press the shutter button half. In external lightmeter Sekonic, aim or point tool to midtone areas (areas that are / dark midtone brightness), and the LCD screen will indicate exposure settings, including f-stop is recommended for wear.

And when you use Incident Lighmeter you can start to use it with placing your subject and direct white dome light lightmeter facing direction and pressing the button on the lightmeter.

If the direction of the light from the side that illuminates your subject, point the dome into the lens to get the f-stop calculations are accurate. Setting the appropriate F-stop will appear on the LCD screen. 

When you know two mode of lightmeter, now you can choose good and suitable lighmeter in your photography project with select good camera too.
