Pressure switch survives aggressive
steam
A saturated-steam-resistant pressure switch features a diaphragm made from a newly developed FKM elastomer material.
Beck has equipped its Model 901 pressure switch with a newly developed diaphragm material The basis for the saturated steam-resistant version is a special, newly developed FKM elastomer material
This new material allows direct contact possible with aggressive saturated steam for example.
As a result, the series 901 pressure switches are advancing into new temperature zones up to 140C and, depending on the model, can be adjusted to provide switch-points from 100mbar to 12bar without material fatigue.
Conventional elastomers can quickly lose their elasticity when used with saturated steam resulting in a detrimental shift of the switch-point.
In extreme cases, they become brittle or cracked and so represent a potential danger as a result of failure.
Also, a new diaphragm suitable for food processing is available from Beck.
EPDM meets the requirements of the FDA Standard 21-CFR 177.2600. Request a free brochure from PVL ...
