Product Description
Overview Line voltage pressure controller that provides automatic operating control, automatic limit protection, manual reset limit protection, and 4-20ma modulating firing rate control for pressure systems up to 300 psi. Features May be used with steam, air, non-combustible gases or fluids that will not corrode the pressure sensing element. Models available in 15, 150, 300 psi maximum set points. LED indicators show limit function/lockout. Reset function easily accessible under cover. Clear cover allows set point and differentials to be read (but not adjusted) without opening the cover.
