KOBOLD Series NSM, NSP, NSE and NST float switches enable liquid levels to be monitored easily. Filling levels may also be controlled by installing at least two floats, one as a minimum, the other as a maximum limit switch. The floats can be run to a latching relay (sold separately) for automatic level control. These switches can be installed wherever magnetic liquid level switches are unsuitable due to the risk of the float jamming with dirt particles or coating. Even extremely aggressive, hot, dirty or pulplike media may be monitored with these float switches (depending on the shape and material of the float).
