PROJECT TITLE:
Heat Detector
Aim:
To make a heat detector.
Materials Required:
1. Wooden box
2. Cardboard piece
3. Rubber band
4. Pin
Procedure:
Stretch a rubber band around the sides of a wooden box. Then cut out a arrow from the piece of cardboard and, mount it on a pin, and push the pin under the rubber band. If you now bring a burning match or candle close to the rubber band, the cardboard arrow will rotate anti-clockwise. Move the flame near the other end and the arrow rotates clockwise. The heat causes a portion of the band to contract, rotating the pin and arrow. This is because rubber contracts when heated and expands when cooled.
What else can I help you with?
What are Two type of heat detectors are?
They are: -Rate of Rise -Fixed Temperature Rate of rise detectors can be adjusted to different temperature settings to which detect heat. Once the temperature in that area reaches your chosen point, it will activate the heat detector. Fixed Temperature is when you buy a heat detector, it only has one fixed detection point on it. So you cannot adjust this.
What are the advantages and disadvantages of automatic heat detector?
the circuit is small in size.......simple ckt......no. of sounds can be generated....but disadvantage is not used in large type of applications
When was the fire detector invented?
The ionization type smoke detector was invented in 1931 in Switzerland.
What type of detector can prevent injury from a faulty furnace?
An easily found carbon monoxide detector
What metal can a metal detector detect?
A metal detector can detect all types of metal....depending on in what type of soil it is in.
What is non coherent detector?
A non coherent detector is a type of device that does not need a receiver carrier to be phase locked to a transmitter carrier. A coherent detector demodulates signals.
What is the function of a heat detector system?
To detect heat from/of a fire or something which is dangerously hot in cerrtain apllications. They are connected to fire alarm system where when the heat detector detects heat, it activates the fire alarm causing the need to evacuate. These type of devices are used in applications where smoke detectors would not be practicle. For example, kitchens, boiler houses etc.
What is type of linear equalizer?
1:linear transversal and 2: Linear lattic equalizars
Who took ever took a lie detector test in their life?
its easy to make by your own hands! but the real ones are tested to the prisoners of jail. when they are taken to court, some type of lie detector is run and if they lie they will go to jail.
How are linear equations and functions alike and how are they different?
A linear equation is a special type of function. The majority of functions are not linear.
What type of perspective is used in the painting by pietro perugino?
linear perspective
What was the type of brain cell discovered by Hubel and Wiesel?
feature detector
