Aplisens ERH Level Switch

Aplisens ERH Level Switch

Aplisens ERH Level Switch are used for point level detection of liquids in all type of vessels. Operation without external power, side or top mounting, wide temperature and pressure ranges, various process connections, stainless steel wetted parts, Ex version and marine certificates make it a universally applicable level switch. Level switches are available with floats in two sizes: Ø64.5 x 130mm or Ø52 x 162mm).
