STEMCO Capillary Switch

STEMCO Capillary Switches are Temperature Compensated

STEMCO, a division of Senasys, Capillary Switches stand out from other capillary switch manufacturer’s because they are temperature compensated.

A capillary switch should be temperature compensated to adjust the switch’s performance when changes in temperature occur. For instance, a capillary switch may be set for the contacts to close at 150°F, but the fluid or air temperature within the equipment may reach 250°F. If the capillary switch wasn’t temperature compensated, the switch may have a poor reaction to the high temperature within the equipment and cause failure.

At Senasys, we expose the capillary tube to a higher temperature during our inspection process to ensure the diaphragm assembly will react as it should even if there is extreme environment changes. The majority of our current assemblies are ambient temperature compensated to 250°F. Other custom temperature compensation options are available. Click here to send us your requirements!
