25-100 psi (1.7-6.9 bar) ±2.0 psi (0.138 bar) +2% of setting 5 psig (0.28 bar) +10% of setting
* Accuracy and set point of units may change due to the effects of temperature.
** These numbers are for the standard microswitch. With either the -SP or -10A option, the values are typically 20% greater than those
listed. With the -RD option, the values will be typically 25% less than those listed. In certain applications deadband can be tailored
and controlled to customer specifications. Consult factory for details.
