![]() ![]() These consist of two metals, which are used as strips or platelets and have different thermal coefficients. What is a bimetal temperature switch?īimetal temperature switches determine the temperature using a bimetal disc. Temperature switches, on the other hand, trigger a switching operation depending on the temperature and are used to open and close circuits. The temperature controller is thus responsible for the display, control and monitoring of temperatures. The desired set point is adjusted via an actuator. What is the difference between a temperature switch and a temperature controller?Ī temperature controller can, using a temperature probe, determine the actual temperature and then compare it with the set point. Another switch model is the gas-actuated temperature switch, which is used especially in safety-critical applications. Bimetal temperature switches, on the other hand, operate with low accuracy, but are very compact and inexpensive. Here, the user can change the limit value themselves and set several switch points. When a high accuracy is required, an electronic temperature switch should be used. The mechanical temperature switches differ in the various switch models, such as bimetal temperature switches and gas-actuated temperature switches. Generally, a distinction is made between mechanical and electronic switches. What types of temperature switches are there? Basically, the thermal switches are responsible for monitoring the temperature of machinery and equipment and are used for temperature limitation. This function is used as protection against overheating or overcooling. The switching status of the temperature switch changes depending on the input temperature.

Walker Products will not be held responsible for any use of this information. The codes listed for this product type are common instances that may relate to your vehicle and should be used as a guide only. OBD II is now the standard in diagnosing vehicle emissions, which was implemented by all automotive manufacturers in 1996. In an effort to reduce vehicle emissions, the Environmental Protection Agency (EPA), mandated that all vehicles manufactured after 1996 would be equipped with OBD II (On Board Diagnostics 2) technology. The following OBD II error codes are the most commonly found with this product type. Poor idle (necessary to pump the gas pedal to keep vehicle running).Black smoke coming from vehicle’s exhaust.Symptoms of a failing Engine Coolant Temperature Sensor may include: It may turn the cooling fan off or on, open the exhaust gas recirculation or communicate the need for a richer fuel mixture.Ĭommon causes of Engine Coolant Temperature Sensor failure include: The vehicle’s computer will use this information to adjust certain engine functions to keep engine temperature at an ideal level. This gives an indication of how much heat the engine is giving off. The Engine Coolant Temperature Sensor (CTS or ECT) uses electrical resistance to measure the temperature of the coolant/antifreeze mixture in the cooling system. ![]()
