REED MAGNETIC SENSORS

Level sensors

celduc® relais offers a large range of standart or specific level and flow 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 function by reversing the float or using 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.

Liquids compatability

1
  • → Compatible with acid: acetic, citric, formic, lactic, nitric diluted, phosphoric, suplhidic diluted; soda; alcohols: ethanol, methanol, propanol; glycol; mineral oil; water
  • → Not compatible with the following solvents: chloroforme, methylene chloride, trichoroethylene, toluene; hard acids.
  • → Compatible with fuels, engine oil, kerosene, lubricant oil, mineral oil, vegetable oil
2
  • → Not compatible with almost all acids, methylene chloride
  • → Acceotable resistance to water
3
  • → Compatible with almos all the liquids except hard acids.

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

The above advantages allow a safety use, repetitiveness, precision and minimum maintenance.

 

Screw position sensors

General use screw sensors for industry and household use:

  • — Rabbet sensors
  • — Doors opening
  • — Protection cover presence
  • — Household appliances
