Fischer TS61 – Temperature switch for liquid media, air (UL, VDE approved)

Fischer TS61 is temperature monitor and controller with limit switch contact. Media contact material is of stainless steel, thereby making it corrosion resistant. Vibration resistant, high switching contact capacity, high temperature operation are some other features of the product.

Make: Fischer Messtechnik (Germany)
Model: TS61

Fischer TS61 temperature switches are used for monitoring and controlling out-of-limit temperature conditions in heating and cooling systems, pipes, process vessels, process engineering and storage vessels. TS61 is ideally suitable for monitoring, control and protection of compressors, motors, pumps, hydraulic power systems, plastic processing machines, chillers etc.

Operation Principle:

Fischer TS61 is housed in stainless steel casing and is highly vibration proof. When the process temperature exceeds the set-point value, the switch contacts open to break the electrical load circuit. The switch contact close automatically when the temperature drops below set-point value.
