Oil based liquids can cause deformation of the sensing tip and must be tested for compatibility. NOTES b) Before use check that the fluid in which you wish to use these devices is compatible either with Polysulfone or Trogamid. c) Voltages applicable to output value stated.OUTLINE DRAWING HOUSING SPECIFICATIONS All dimensions shown in mm.
