Application Detail

Overview

The Autoclavable Pressure Vessels are designed to be sterilized completely and repeatedly in an autoclave with temperatures of up to 130 °C (266 °F) and a pressure of 2 bar (g). The integrated measuring devices as a whole have to withstand these sterilization processes, and still assure the highest accuracy and reliability in operation at any time.

The Anderson-Negele solution

The EM pressure gauge is only 90 mm in diameter but presents an excellent visibility in the big display. The structure is all welded and in stainless steel, so that can resist regular andrepeated autoclaving without any restriction. The multiple protection of the diaphragm assures a long-lasting quality even with superior mechanical stress or frequent disassembly for control or re-calibration reasons.

The actuation fill is a special medical white oil which is 100 % compliant to FDA standards, the housing itself is non-filled forautoclaving purposes, the surface quality of the diaphragm is electropolished with Ra ≤ 0.2 μm. The device completely meets highest AMSE BPE standards and comes with a complete certification and documentation package.
