Repeatability / Deadband

 Pressure Range Code

Pressure Range 

Repeatability

Average Deadband*

10

10-30 psi (0.7 to 2.1 bar)

± 1.5 psi (0.103 bar) + 3% of setting

3.5 psi (0.28 bar) + 12% of setting

20

25-75 psi (1.7-5.2 bar) 

± 2.5 psi (0.172 bar) + 3% of setting

30

65-300 psi (4.5-20.7 bar) 

± 5.0 psi (0.138 bar) + 3% of setting

20 psig (1.38 bar) + 12% of setting 

40

250-1000 psi (17.2-69 bar) 

± 15 psi (1.03 bar) + 3% of setting

45 psig (3.10 bar) + 13% of setting 

*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 are typically 25% less than those listed. In certain applications, deadband can be tailored and controlled to customer specifications. Consult factory for details.
