Repeatability / Deadband

 Pressure Range Code

Pressure Range 

Repeatability

Average Deadband*

10

5-15" Hg (169-508 mbar)

± 0.71" Hg (24 mbar) + 2% of setting

3.05" Hg (103 mbar) + 7% of setting

20

12-28" Hg (406-948 mbar)

± 1.63: Hg (55 mbar) + 2% of setting

6.1" Hg (207 mbar) + 8% of setting

* These numbers are for the standard microswitch. With either the -SP or 10A option, the values are typically 50% greater than those listed. With the -RD option, the values will be typically 20% less than those listed. In certain applications, deadband can be tailored and controlled to customer specifications. Consult factory for details.
