Bimetal disc thermostats are the measuring device of choice for many applications

A bimetal disc thermostat is used to control the way an appliance responds to temperature changes. A bimetal thermostat is often the thermal measuringg devise of choice because it is reliable, dependable and cost effective. The response of a bimetal disc to thermal changes is the most important element of any bimetal thermostat. As the bimetal disc reaches its preset temperature, it snaps intto a concave position. The bimetal thermostat is a popular product because it provides both sensing and switching functions in one product at an economical price.

The process of temperature measurement

The purpose of any temperature measuring device is to measure the hotness or coolness of some object. Bimetal disc thermostats are preferred over many thermal devices because they provide accurate measurements that get as close to the actual temperature as possible. These devices have a high resolution, meaning they are able to register even the slightest temperature change. The accuracy covering a wide range of measurement is an important feature as well.

Bimetal disc thermostats in action

Bimetal disc controls are used in many major appliances including HVAC equipment. The most common used bimetal disc is the three-quarter inch disc. The three-quarter inch disc is a reliable device with flexible capabilities. It works well with appliances requiring mjor electrical currents. You can get a bimetal disc with a manual reset that you perform on yur own, or an automatic switch action. The automatic control bimetal discis available in a single-pole single-throw or a single-pole double-throw contact order You can even get a bimental disc in a double-pole single throw switch action arrangement when you want to break two lines of electrical current at once at a single temperature setting.

The availability of three-quarter inch disc temperature controls

There are a variety of 1/2" and 3/4" (half-inch and three-quarter inch) inch disc controls available. They each have their own mounting brackets and configurations to meet the requirements of a specific application. Some common devices include:

• Sealed controls: This bimetal disc thermostat is an epoxy-sealed device meant to be used in humid conditions where moisture and condensation are present. Refrigeration and HVAC products are good examples. This type of bimetal disc comes with your choice of a SPST or SPDT switch action and various mounting options.

• Adjustable controls: This bimetal dsic device has a high capacity for electrical current. There are adjustable functions available such as required for a thermostat control for an air conditioning or heating unit. These discs have two mounting options available: junction box or fan application.

• Electric water heater controls: This unique bimetal disc design functions to accommodate more rugged applications that require accuracy and reliability while maintaining the necessary safety requirements of the electric water heater industry. It comes with a manual reset button for protection against excessive temperatures.

There are many more 1/2" and 3/4" (half-inch and three-quarter inch) inch bimetal disc devices to choose from.

Temperature measurement you can count on

A bimetal disc is what makes bimetal disc thermostats such accurate pieces of equipment. The temperature settings are determined by the manufacturer unless otherwise specified. They are also designed to be tamper proof. This is to ensure appliance safety. With so many bimetal disc designs available to complement various applications, bimetal thermostats are the preferred choice of several industry applications.
