Bimetal is a temperature sensor or a temperature sensor which is popular because of its simplicity.<\/span> Bimetal common on electrical appliances such as electric irons and lamps or lights dimers great power.<\/span> Bimetallic temperature sensor is made of two different metal plates muainya coefficient (\u03b1) are glued together.<\/span> When a metal is heated there will be an expansion, the amount of expansion depends on the type of metal and the high operating temperature of the metal.<\/span><\/p>\n

When two metal plates are glued to each other and heated, the metal has a higher coefficient of expansion expands longer while having a lower expansion coefficient expands shorter.<\/span> Hence differences in the expansion reaction the bimetal will bend towards the metal muainya lower.<\/span> In its application can be formed into a bimetal switch Normally Closed (NC) or Normally Open (NO).<\/span>

From the merger of two of the different metal expansion coefficient is applicable to the following formula:<\/span>

Where in praktikny tB \/ tA = 1 and (n + 1) .n = 2, so that:<\/span>

\n \u03c1 = radius of curvature<\/span>
\n t = thickness total lines<\/span>
\n n = ratio of elastic modulus, EB \/ EA<\/span>
\n m = comparison thick, tB \/ tA<\/span>
\n T2-T1 = temperature rise<\/span>

The basic concept of making a bimetallic temperature sensor is utilizing expansion coefficient of two different metals and applied as a switch Normally Closed (NC) or Normally Open (NO), which will change its position when the temperature \/ cold and hot temperatures.<\/span> As the name suggests, the temperature switch is a switch that bekerjany disconnecting or connecting electricity because of the influence of temperature.<\/span> So at a certain temperature the contact points of the switch temperatu be connected or disconnected, temperature switches are widely used for air conditioning equipment, protective equipment against excessive temperature and others.<\/span> Temperature switches often called thermal switch or thermostat switch.<\/span><\/p>\n

Working Principle Thermo Switch<\/strong><\/span>
\n<\/strong> Thermal swtch usually have a lever point of contact that is made from a piece of bimetal plate.<\/span> Bimetal are two metals that have different length expansion coefficient are bonded by welded into one.<\/span> At the nominal temperature of a straight bimetal plate.<\/span> If the plate is heated, the bimetal metals having a length greater expansion coefficient expands longer than metal has long expansion coefficient smaller.<\/span>
\n<\/a><\/p>\n

Metal expands longer will push the metal expands shorter so that the bimetal plate will curve to the metals having a smaller expansion coefficient value.<\/span> The opposite will happen if the bimetal plate cooled.<\/span> Thermal switches typically have a surface which is connected to the bimetal plate and the surface of a contact point that will be associated with sources of heat or cold.<\/span>
\n<\/a><\/p>\n

Bimetallic plate is a lever connected to the contact point and the contact point is connected to a terminal or pin to be connected to a source of electric current.<\/span> Bimetal pieces are two pieces of metal (usually brass and iron) that has a different length expansion coefficient are riveted together.<\/span> Bimetal pieces are very sensitive to temperature changes.<\/span> If pieces of bimetal is heated, it will curve to the length expansion coefficient of the metal is small.<\/span><\/p>\n

When cooled, the bimetal piece will curve to the length expansion coefficient of the metal which is great.<\/span> At normal temperatures bimetal pieces will be the same length and the second piece in a straight position.<\/span> If the temperature rises two pieces will undergo expansion by increments of different lengths.<\/span> As a result, pieces of bimetal will bend toward the metal having a small length expansion coefficient.<\/span> The bending of the bimetal can be used for various purposes eg alarm bimetal switch, or a bimetal thermometer.<\/span>

If pieces of bimetal is heated, it will curve to the length expansion coefficient of the metal is small.<\/span> When cooled, the bimetal piece will curve to the length expansion coefficient of the metal which is great.<\/span> Bimetal pieces can be utilized in a variety of purposes, for example in the bimetallic thermometer, bimetal thermostats on electric iron, alarm switch bimetal, bimetal electrical fuse.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
