How does a snap disc thermostat work?
Snap Disc, or snap switch thermostats are bimetal mechanical thermostats that function via the thermal expansion and contraction of a bimetal disc that “snaps” from a convex to a concave shape at a set temperature. When the disc “snaps”, it either completes or interrupts a circuit.
What is bimetal thermostat?
Bimetal Thermostats use two different kinds of metal to regulate the temperature setting. When one of the metals expands more quickly than the other, it creates a round arc, like a rainbow. As the temperature changes, the metals continue to react differently, operating the thermostat.
What is a thermostat snap switch?
Open Air Thermostats sense heat through convection rather than conduction. Snap Disc Thermostats utilize a bimetallic, temperature-sensitive disc that snaps open/close switch contacts disrupting/re-estabishing continunity. Open air thermostats sense temperature through convection rather than conduction.
What does a therm-o-disc do?
Therm-O-Disc is a maker of thermostats for various appliances. On a dryer the thermostats control the operating temperatures and serve as safety backups.
What is a SnapStat?
Thermal Switches for Harsh Environments – SnapStat (0 – 300 Fahrenheit) CPI’s SnapStat thermal switches have a bimetal snap disc that actuates a miniature micro switch. This double snap action makes these switches virtually immune to shock and vibration.
How does a bimetal work?
The bimetallic strip consists of two thin strips of different metals, each having different coefficients of thermal expansion. Due to this property, when the temperature changes, the metal strip at one side expands and the other does not, which creates a bending effect.
What is a bimetal switch?
A bimetal switch changes its switching status relative to the temperature. If the temperature is sufficient, the bimetal bends, thereby actuating a snap-action switch. This switch can open or close a circuit and in so doing start or stop a process (e. g. heating, cooling, pumping).
What does a therm o disc do?
What does a snap disc do on a pellet stove?
This part may be called a limit switch, snap switch, or snap disc. These temperature sensing switches serve as a safety feature and typically control auger motors, blowers, and other major components in your stove. Depending on the brand and model, you may have multiple high and/or low limit switches.
What is the purpose of the letter designations on low voltage thermostats?
But people are often confused by the system by which the low voltage wires are labeled, which can look different in an old thermostat than it does in a new one. Contrary to popular belief, the letters do not correspond to wire colors, but rather are used to indicate the various function signals controlled by each wire.
What does the bimetal snap on Therm O Disc do?
Since 1947, Emerson’s Therm-O-Disc™ has been the global leader in the design, innovation and manufacture of temperature sensors and controls. Bimetal disc thermostats are thermally actuated switches. When the bimetal disc is exposed to its predetermined calibration temperature, it snaps and either opens or closes a set of contacts.
Which is the best bimetal disc thermostat?
¾” Snap Action Bimetal Disc Thermostat: HB-7 uses snap action to create high-speed contact separation, giving you a versatile, cost-efficient method of regulating temperatures. AMT-P1 Series Bimetal Thermostat provides more reliable, safe protection for your circuits.
What does the bimetal snap on a thermostat do?
This breaks or completes the electrical circuit that has been applied to the thermostat. The 44T/48T series line of bimetal temperature switches provide high contact speed separation resulting in exceptional life characteristics.
What is a snap switch also known as snap action thermostat?
What is a snap switch also known as Snap Disc or snap action thermostat? Snap Disc, or snap switch thermostats are bimetal mechanical thermostats that function via the thermal expansion and contraction of a bimetal disc that “snaps” from a convex to a concave shape at a set temperature.
