Information About L404A1370
The L404A1370 belongs to the Honeywell Pressuretrol L404A series, which are high-limit controllers intended for use in steam or gas pressure systems. It features a stainless steel diaphragm for pressure ranges from 5 to 50 PSI, with SPST snap-acting switch functionality. This model offers subtractive differential pressure control and supports external adjustments via a visible scale through a clear cover. It operates using a bellows mechanism and is designed for use with ¼" NPT pipe threading or surface mounting. The unit is UL and CSA approved and rated for ambient temperatures up to 150°F.
Key Features:
- Pressure Range of 5–50 PSI: Adjustable via external scaleplate, with mid-scale differential of approximately 6–12 PSI.
- SPST Snap-Acting Switch: Simplifies control with reliable open/close contact behavior.
- Diaphragm Sensing Element: Uses stainless steel diaphragm for accurate sensing within the target pressure range.
- Subtractive Differential: Designed to respond to pressure decreases below setpoint.
- Clear Plastic Cover: Allows for easy inspection and access to pressure adjustment screws.
- ¼" NPT Threaded Mounting: Supports both pipe and surface installation methods.
- UL and CSA Approved: Certified for industrial and commercial compliance.
- Ambient Temperature Limit 150°F (65°C): Ensures stability in hot environments.
- Electrical Ratings: Rated for up to 8.0 A at 120V AC and 2.4 A at 120V DC.
- Compact Design: Dimensions approximately 5.5" wide × 6.5" high × 2.5" deep.
The L404A1370 provides robust and accurate switching for medium-range pressure control tasks in steam heating and air systems.
