Miniaturized pressure transducers / embedded

brief description

The pressure transducer series SME is designed and developmed for applications with restrictions in space or weight.

The SME series is available in smal pressure ranges of up to 20 bar in a housing version of Ø15mm outside and M10x1 pressure connection. For pressure ranges of 20 bar and up to 600 bar a version with a Ø12mm outside diameter an M8x1 thread is available.

The total length of about 50mm ( including thread and cable outlet ) and the total weight of about 50 grams gives space and room for applications with space and weigth limitations and best solutions to integrate the sensors as embedded sensors.

Typical outoput signals are ratiometric voltage output as well as voltage output up to 5Vdc with a 12V supply. Optional low power supply of down to 2.8V can be provided as well as a I2C digital output.

Products from the SME series can be supplied with a pressure port restrictor to reduce pressure spikes especially in hydraulik systems. The diameters of the restrictors are 0.6mm or 0.3mm. The pressure port and stainless steel sense element are completely electrobeam welded and provide save over pressure and burst ratings.

product characteristics

  • minimum weight and total length with maximum over pressure and burst ratings
  • fully welded construction
  • high chemical / media compatibility by the use of stainless steel
  • high rate of pressure cycle widthstand
