Brand: JOHNSON CONTROLS Model: F61KB-11C Operating voltage: 220V AC (V) Overload current: 10 (A) Certification: CE F61KB Liquid Flow Switches Overview F61KB series of liquid flow switches for sensing changes in liquid flow through the pipeline, for example, water, ethylene glycol or other non-hazardous liquid. When the liquid flow rate exceeds or falls below the set flow rate, the single-pole double-throw switch contacts (SPDT) make a circuit is turned on and off while the other loop of the flow switch is normally used in a chain reaction or to "stop "protected space. F61KB flow switch can be installed according to the flow rate of the pipeline, using different blades. features - fluid pressure up to 1034kPa, a wide scope of use - adjust the number of blades and trimming blade length sections, to adapt to different diameters and flow rates needs - adjustable set point, the user can choose according to the needs of the system switch is used to measure the application of the liquid flow through the pipeline, such as water, ethylene glycol or any brass, phosphor bronze, non-corrosive and no effect on the sealing properties of the liquid. Not suitable for hazardous liquids. It is typically used in applications requiring a chain reaction or "stop" protected places, such as in a critical or high-value products to be added to protect the place, the switch is often used as a stand-alone backup control, and stop when the chiller system, with F61KB refrigeration compressor flow switch off the power, in order to reduce the possibility of freezing cold machine. Commonly used models and technical data Model F61KB-11C Maximum fluid pressure of 10 bar Fluid temperature up to 120 ℃ minimum 4 ℃ ambient temperature 120 ℃ adjustment method with the following adjustment screw cap with pipe connection 1'' pipe thread (male) Flow see flow meter housing and covers material tensile steel connecting tube brass internal parts of brass and phosphor bronze brass and phosphor bronze valve rated current, voltage, 159 (8) A.220V AC
