Jumo’s advanced function bimetal switches

January 2014 Operator Interfaces, Switches & Relays

Jumo’s bimetal switches are used in a wide variety of applications, such as cooling or heating circuits, compressors or engines. These switches have now been developed for applications in compact plants. The switching element is placed directly in the heating process and can be combined with a temperature sensor.

Bimetal switches are threaded and can be directly screwed into the process, saving on installation time and offering an advantage for local temperature monitoring and indication. The type 608301 can also be combined with a Pt1000 temperature sensor allowing two functions to be combined in a single enclosure.

The temperature sensor can be connected to a controller to control the heating process, while the bimetal switch mechanically safeguards the process by opening the contact once the switching temperature has been reached.

The user now saves half the time and material installation costs installing the sensors, because previously two installation locations were necessary: one for the temperature sensor and one for the bimetal switch. With this new switch/sensor combination, one of these installation spots is no longer required making it perfect for difficult to reach places and smaller plants.

The switch can either be retrofitted in existing plants or installed in new developments. A large selection of electrical connection options, ranging from an M12 connector or DIN bayonet to a permanently connected cable, ensures that the switch can be used in a variety of application environments.
