New Scient for Hobbyists – How to Use a Digital Oscilloscope?

A digital oscilloscope is a device or piece of equipment used to check out all kinds of signals in a variety of ways. For electronic technicians and electronic engineers, you will use digital oscilloscopes to watch how signals change in circuits you can also use this equipment to locate any fault in radios, television and other similar pieces of equipment.

Like a tester or digital multitester, an oscilloscope has probes to let you feed in electric currents through coaxial cables. You can also attach a transducer and use the device to measure just about anything. A microphone can be used together with an oscilloscope to study sound waves. You can attach a thermocouple to study temperature changes in a system. You can also use a piezoelectric transducer to study vibrations.

How a Digital Oscilloscope Works

A digital oscilloscope works like a cathode-ray tube television. In a TV, electron beams are made to scan back and forth a screen coated on the back with chemicals called phosphors. Every time the beam hits the screen, these light up the phosphors. The electron beams sweep across the entire screen and build up the picture that is seen on the screen. Electron beams do it all over again until you see a moving picture. In an oscilloscope, electron beams work the same way creating a picture graph. When you see a line drawn on the screen of the oscilloscope this is actually an electron beam moving up and down.

The electrical signals drawing into the x and y connections become the x and y values on your on-screen chart. Because there is a one-to-one relationship between these two, a traditional oscilloscope is an analog device.

How do You Use a Digital Oscilloscope?

1. Connect the signal you want to study to the y-circuit and use the x-circuit to find out how the signal varies over time.
2. You can connect the second signal to the x-circuit and then study how the y and x signals behave and vary together.
3. Switch the oscilloscope on and plug it into a signal. You will see a trace forming against the background of the on-screen graph.
4. If the trace is too small to adjust the calibration of the x and y-axes. This is just like using a differently sized scale when you’re plotting a chart on paper.
5. Turn the Time/Division control or Time/Div or Secs/Div. This will alter each x-axis division of the screen so the incoming signal can take more time to move across.
6. Turn on the Time/Division control to set to 0.5 seconds per division. This will spread out to take up the twice as much horizontal room. This is now represented by two divisions on the screen.
7. Adjust the y-axis control labeled Volts/Division or Volts/Div the same way. Make the trace larger to fill the entire screen so you can use the graticule for more accurate measurements.

Types of Digital Oscilloscopes

There are a variety of oscilloscopes. The first ever or traditional oscilloscopes were based on cathode-ray tubes (CRTs). These are large and heavy; require large amounts of power and expensive. Basic oscilloscopes are also unreliable and therefore these were replaced by more convenient and reliable LCD oscilloscopes.

1. LCD Oscilloscopes

Instead of using moving electron beams to draw graphs and traces, LCD oscilloscopes use digital electronics. These are more effective because these can mimic what’s happening with older technology. LCD oscilloscopes are very easy to carry anywhere because these are made of light materials. These are less expensive and compact. Some LCD oscilloscopes can even fit your pocket.

Compared to using traditional oscilloscopes that use analog technology (these devices display different signals on the screen that correspond according to the signals you feed into them), LCD oscilloscopes are digital. These use analog-to-digital converters to turn incoming analog signals into numeric or digital form. The values are then plotted on the screen.

2. USB Oscilloscopes

Because your computer, tablet, or smartphone already has a CRT or LCD display, you don’t need to buy an oscilloscope if you are just going to use one for occasional hobby use. Cleverscope is a company that sells inexpensive, plug-in oscilloscopes that simulate the circuitry in a traditional oscilloscope. This kind of oscilloscope uses USB connectors or corresponding leads that will work with mobile devices. This will display a trace on your PC or mobile screen. A USB oscilloscope can be used on the go or in the field however some technicians and engineers still prefer to use reliable LCD oscilloscopes.

Temperature Sensor Types for Temperature Measurement Device

Temperature Sensor Types for Temperature Measurement

Temperature sensors are used to evaluate the amount of heat or the coldness. The coldness or the heat energy that is generated by any system or the object. It shows the difference in the heat or the cold levels if there is any change in the temperature. The output is produced in analog or digital output. Different types of sensors are available with different features. Basically there are two different physical types of temperature sensors.

Temperature Sensor Types for Temperature Measurement Device

Contact Temperature Sensor Types

This type of sensor should be contacted physically with the object which should be sensed. The changes in the temperature will be shown in the monitor. It is widely used to find liquids, solids and gases.

Non-contact Temperature Sensor Types

This temperature sensor use radiation and convection to find the changes in the temperature. It is used to find the gases and the liquids that emit energy that is radiant. The radiant energy is detected when it is transmitted in infra-red radiation.

Temperature Sensor Types

The contact and non-contact temperature sensors are classified as:
• Electro mechanical
• Resistive
• Electronic

The Thermostat

This is a electro mechanical type temperature sensor which is a contact type. It contains nickel, aluminum and copper. These metals form a bi-metallic strip through bonding. The bimetallic strip is also used as mechanical or electrical switch. It is widely used in the furnace and the boilers and in radiators of vehicle to find the heat levels.

The Bi-metallic Thermostat

In this thermostat two different metals are fixed against each other back to back. If it is cold, then current will pass as the contacts of the metals are closed whereas if it is hot then one of metal of the tow metals will raise more and the bimetallic strip that is bonded will bend upwards to prevent the current flowing in.

Thermostat temperature sensor

On/Off Thermostat
In regard with the bimetallic strips, there are two different but main types and it is differentiated depended on the movement as per the changes in the temperature. The ON/OFF type is otherwise called as snap-action types which produces instant ON or OFF action as per the temperature point. The action will be produced on the electrical contacts. The creep action type of thermostats is also called as slower types. The position of the strip is changed gradually according to the changes in the temperature.

Temperature Sensing and Control

The snap action or ON/OFF type thermostats are mostly used in homes to control the temperature points of irons, ovens, immersion hot water tanks, iron and also in domestic heating system.

The creeper type thermostats are usually bimetallic spiral or coil which will unwind as per the temperature changes. This type of thermostat is quite extra sensitive to the changes in temperature. The snap action and creeper type of thermostat are cheaper comparatively.

The Thermistor

This is one of the temperature sensor which consists of special type of resistor. When there is change in the temperature, the physical resistance of the resistor will change. It is usually made up of ceramic materials like manganese, oxides of nickel, cobalt coated glass and other materials.
