Honeywell L404T1055 – Pressuretrol Controller 5-50 psi

Description

Overview
Oil pressure sensing devices for use on oil burner systems using any type of fuel oil, including heavy pretreated oils.
Features
Clear plastic cover allows observation of the pressure settings.
Models have snap-acting switching to open or close a circuit on pressure rise.
L404T High pressure limit, break a circuit on oil pressure rise above setpoint.
L404V Low Pressure limit, makes a circuit on oil pressure rise above setpoint.
Adjustments are made by screws on top of case.
Mount using 1/4 inch -18 NPT internal pipe threads or surface mount through base of case.
Ground screw terminal.
