celduc relais : standard or specific level sensors using Reed switches

celduc relais® offers a large range of standard or specific level sensors using Reed switches. Our sensors are available in plastic, brass or stainless steel housing, making it possible to use them with various chemical substances and/or operating temperatures. With some sensors, it is possible to invert function by reversing the float or using the sensor upside down. Please see the data sheets for more details. For specific applications (e.g. potentiometric scale, special level sensors) do not hesitate to contact us : products can be developed on request. Working principle : A float fitted with one or more magnets moves with the liquid and actuates, due to its magnetic field, a hermetically sealed reed contact located in the body of the float. Advantages : - One moving part. - The Reed contact is actuated by a magnetic field only : no contact so no wear. - The Reed contact is completely isolated from the liquid so perfectly waterproof. These advantages allow a safety use, repetitiveness, precision and minimum maintenance.
