Instructions for use

  • Before the transmitter is connected to the pressure circuit it is necessary to check whether the measured pressure corresponds with the nominal range of the transmitter. Even a short-time overload over the maximum permissible overpressure can cause destruction of the measuring membrane.
  • In case of using other media than air, nitrogen, water, oil, ethyl alcohol it is necessary to check the resistance of the materials, see the front page
  • For the transmitter sealing it is recommended to use “O” ring 12x2, supplied with the transmitter. While sealing to the thread (Teflon, tow) for liquid media, it is necessary to pay high attention to caution because screwing into closed volume of liquid can cause increase of pressure and destruction of the membrane!
  • Caution when sealing of thread (with teflon or with oakum) in liquid medium, because of screwing into the closed volume of liquid can cause uncontrollable rise of pressure and destroy this way meassuring membranes!
