Pressure Transmitters for Steam Sterilizers

Sterilization is defined as the destruction of microorganisms (including bacterial spores) for the purpose of gaining absolute sterility. An item is considered sterile if the theoretical probability of a living germ existing on it in question is less than 1 in 1 million. Steam sterilization is the safest and most common sterilization method. Known as an autoclave, a steam sterilizer is an instrument that uses heat and pressure and utilizes steam vapor.

Here's how an autoclave works: First, air is sucked in by a vacuum pump. The water then boils, and because the container does not allow water vapor to escape, the water vapor temperature rises above 100 degrees and saturated vapor saturates the inside of the autoclave.

Steam sterilization is done in two ways:

A sterilization time of 3 minutes with an absolute pressure of 3, 04 bar and a temperature of 134°C.

A sterilization time of 15 minutes with an absolute pressure absolute pressure of 2, 1 bar and a temperature of 121°C.
