What is a high temperature switch?
The high temperature limit switch (also known as a furnace plenum thermostat) is a safety device on a furnace that is designed to cut the gas supply when the burner temperature exceeds the safe operating range. When the temperature drops back within the safe range, it will allow the gas valve to open again.
What are temperature switches?
Temperature switches are generally used in industry for limiting temperature. They monitor the temperature of machinery and equipment and, for example, switch off machinery if it overheats or switch on a fan to cool the equipment.
How does a high temperature switch work?
The open thermal control contains a switch with a bimetal electrical contact support. As the switch begins to increase in temperature, the bimetal heats up until it reaches the temperature where it deflects and thereby opens the electrical contacts.
What is a temperature control switch?
A: Temperature switches are typically electromechanical devices, used in industrial and manufacturing processes and are responsible for the monitoring and controlling of temperature, with the ability to turn on and off when a certain temperature is reached.
What is a temperature switch used for?
Temperature switches are specifically designed to be used in boilers, heating systems, circulation pumps, burners, and air heaters. They are typically used across a wide range of general-purpose applications, but are particularly important in industries like foodstuffs, pharmaceuticals and automotive engineering.
What does a high limit switch do?
Turning the fan motor on and off is the high limit switch’s main job. This is the role it plays in every cycle of your furnace’s normal operation. But that’s not the only thing that the high limit switch does. It’s also safety device that helps prevent your furnace from overheating.
What is the purpose of the temperature switch?
What is the function of a temperature switch?
The coolant temperature sensor, also known as the coolant temperature switch, is an engine management system sensor that is used to monitor the temperature of the engine’s coolant. Most coolant temperature sensors operate using electrical resistance to measure the temperature of the coolant.
