What is the factory setting tolerance (non-adjustable products) for the different series?

A. Non-adjustable switches have a factory tolerance of +/- 20% of the set point. There are exceptions to this rule that our sales department can explain. For example, the 0.5″ version of the PSF100A and PSF101 are defined as differential switches that will actuate somewhere between 0.2″ and 0.5″ h2O. PSF103, adjustable switches, also have a factory tolerance of 20%, and the PSF102s generally carry a 10% tolerance except for the lowest settings, which are +/- .1″ on the .1′ to .5″ model.
