Differential Pressure Switch-CL13/CL21/CS31

Click to enlarge image CL13 This pressure switch mainly senses the differential pressure caused by the pressure losses of an air conditioning air filter, detecting the clogging of an air filter and issuing warning, controlling air conditioning system. Additionally, this pressure switch is applied to the observation and controls of pressure in the filter of a clean room and a bioclean room and in a clean room and bioclean room themselves. Features： +This pressure switch is highly sensible and highly reliable, and the pressure resistance has been increased ¡¡by the application of silicone rubber to the diaphragm. +The setting of activating pressure is simply performed by turning the setting knob to set the setting pressure to the graduations of the setting pressure. +The setting lock mechanism has been applied to the setting knob, eliminating the error due to vibration, etc. +A highly reliable and high capacity micro switch has been applied, increasing setting precision. +Small type/light weight. +RoHS directive compatible CL21 This is a differential pressure switch which sends an on and off electric signal in accordance with differential pressure mainly for the application of liquid level warning in a closed tank and the clogging check in a pipe line strainer. A micro switch with extensive application and high reliability is applied to the contact. Features： +This differential pressure switch is extensively applied to general industrial machinery including the differential pressure control in a power station, etc. +The exterior appearance is compact. +The construction is simple. *In case of selecting pressure gauge, choose the pressure range which can be used in between 30-65% of full scale, so that the gauge can give its full capacity. *Using This Differential Pressure Switch If the pressure larger than differential pressure is applied to the one pressure switch will be damaged. So, careful attention is required. Especially at the time of starting and finishing, this type of phenomena can occur. Therefore, a bypass cock or a bypass valve is recommended. CS31 This is a pressure and differential pressure switch mainly developed for air conditioning application, being able to apply to a pressure from 0.05 kPa, differential pressure or vacuum. This is small in size and light in weight. Features: +This is a switch of which multiple stages setting range is from 0.05 kPa to 35 kPa. An appropriate switch including a pressure switch, a differential switch and a vacuum switch can be selected and applied. +This gauge is of small and light weight type. +The setting at low pressure can be possible. *In case of selecting pressure gauge, choose the pressure range which can be used in between 30-65% of full scale, so that the gauge can give its full capacity.
