Bimetalový termostat

In the regulation of heating and cooling, thermostats that operate over a wide range of temperatures are used. In these, one end of the bimetallic strip is mechanically fixed and attached to an electrical power source, while the other (moving) end carries an electrical contact. Free Next Day Delivery.

A thermostat has important main components. How does a bimetal thermometer work? What is a bimetal thermometer?

The little device that makes this possible is the bi-metal , or defrost, thermostat. It is called a bi-metal thermostat because at its heart is a strip made of two metals with different expansion rates, which when heated begins to curve. This switch operates the heater. The strip works as a bridge in an electrical circuit connected to your heating system.

Normally the bridge is down, the strip carries electricity through the circuit, and the heating is on. You will often find long bimetallic strips coiled into spirals. By coiling a very long strip it becomes much more sensitive to small temperature changes. In a furnace thermostat , the same technique is used and a mercury switch is attached to the coil.

The switch turns the furnace on and. In one form, the mechanical thermostat , a bimetallic strip in the form of a coil directly operates electrical contacts that control the heating or cooling source. A bimetallic thermostat device consists of a strip of two different metals having different coefficients of linear expansion.

The bimetallic strip works as an electric contact breaker in an electric heating circuit. Sammax thermostat is used as an example. Thermostats use different types of sensors to measure the temperature. Capillary Thermostat The volume of the material in the temperature sensing part of temperature controller will inflate or deflate when the temperature of the controlled object varies, which causes the film box that is connected to the temperature sensing part inflating or deflating, then drives the switch on or off through a leverage function to keep a constant temperature. The thermostat was invented in the 17th century, and it consisted of a float present in a mercury thermometer and connected to a damper cover placed on a furnace.

When the mercury in the thermometer reached a certain level, the float move causing the damper to close. Although a simple device, it paved the way for modern thermostats. How a bimetallic thermostat switches on and off. An outer dial enables you to set the temperature at which the thermostat switches on and off. The dial is connected through a circuit to the temperature sensor (a bimetal strip, shown here colored red and blue), which switches an electrical circuit on and off by bending more or less.

It consists of a bi-metallic strip. ABOUT US NGT Controls, Inc. Looking For Great Deals? Check Out Top Brands on eBay. Fill Your Cart With Color today!

The most common thermostat found in home appliances is the type known as a bimetal thermostat , so-called because of the way in which the mechanical action to open and close switch contacts is derived. In a bimetal thermostat , two dissimilar metals are bonded together. We only offer bimetal disc thermostats designed by NGT (Nippon GT Corporation), a top Japanese manufacturer respected for its product quality and reliability.

Certified to worldwide standards,these thermostats are widely used in car seat heating, boilers and domestic appliances. A bimetal thermostat is a gauge that performs well under extreme temperature conditions. Made of two sheets of metal that are fused together, this type of thermostat can be used in ovens, air conditioners and refrigerators. It is often understood that the only thermostats that exist are found on the wall of one’s home, used to control the heating and cooling system in the house.

Adjustable bimetallic thermostat switch 0-1Degrees C. However, this is not the only application thermostats are use although practical, there are several more areas where the integration of a thermostat has proven very useful. The thermostat in an iron uses a bimetallic strip, and as the name implies, a bimetallic strip is made up of two different types of metal – with dissimilar coefficients of expansion – that are bonded together. We make a wide range of temperature switches including, bimetal , duct sensing and fluid filled capillary style thermostat switches.

We also produce a number of lines of industrial panel mount control switches as well as a group of micro switches.
