Pressure switch dead zone adjustable, dead zone is not what it means. Please explain in detail Thank you.
Dead zone, DEAD ZONE, in the field of instruments, also known as the instrument of the insensitive area. The change in the amount of input does not cause a limited interval (also understood as sensitivity) of any appreciable change in the output of the instrument. The cause of the dead zone is the friction between the internal components of the instrument and intermittent.
Dead zone = sensitivity = hysteresis.
for example:
Set the value of 100KPa, dead zone 1%, then the deviation of ± 1% of the range is not action, that is, 99KPa ~ 101KPa no action. This can avoid frequent action.
In the design, the process of measuring parameters of the hysteresis requirements are uncertain, you can use the dead zone adjustable products, commissioned by the site debugging state set dead zone value.
General pressure switch dead zone is not adjustable, and some pressure switch dead zone can measure the mechanical properties of components to adjust the dead zone size, but change the component characteristics may cause the switch to malfunction or moving! The The So avoid free to adjust!
