Honeywell L404F1094 pressure switch

Honeywell L404F1094 pressure switch (Pressuretrol). Reliable pressure control for steam, air and non-aggressive gases in industrial systems. Honeywell L404F1094 pressure switch (Pressuretrol) is a high-quality electro-pneumatic controller designed for control and protection of systems with overpressure. The device is widely used in steam boilers, air compressors and other industrial equipment to maintain working pressure and provide emergency shutdown when permissible limits are exceeded. If your boiler or compressor does not build pressure, does not shut off when the upper limit is reached, or conversely does not start when pressure drops below the set point, the cause may be a malfunction or misadjustment of this relay. Technical specifications: Parameter Value. Part numbers: L404F1094, L404F1094/U, 534.676.027. Manufacturer: Honeywell (USA/Mexico). Type: Pressuretrol — automatic reset pressure switch. Application: Steam, air, non-combustible gases, liquids non-aggressive to the sensing element. Working pressure adjustment range: 20 – 300 psi (1.38 – 20.68 bar / 138 – 2068 kPa). Maximum working pressure: 25 psi (for normal operation) / maximum withstand pressure — 350 psi. Differential (pressure difference): 20 – 50 psi (adjustable, subtractive type). Contact type: SPDT (single-pole double-throw). Contact action: Switching on pressure rise: closes R-W, opens R-B. Reset mode: Automatic (Auto recycle). System connection: 1/4" NPT (female thread). Electrical connections: Screw terminals. Contact ratings (120 V): 8.0 AFL, 48.0 ALR, 10.0 A (resistive). Contact ratings (240 V): 5.1 AFL, 30.6 ALR, 5.0 A (resistive). Sensing element: Brass
