Supported Applications
The Weiss Series LF602 consists of liquid-filled, stainless steel industrial pressure gauges engineered for severe service conditions involving vibration, corrosion, and pulsating pressures. The product overview identifies suitability for agricultural equipment, hydraulic systems, oil field equipment, pumps, compressors, and car wash systems.
Operating Conditions & Performance
The Series LF602 is a 6" gauge featuring a Type 304 stainless steel case with a polished stainless steel bayonet ring. It utilizes a tempered glass window for durability. The measurement range covers Vacuum, Compound, and Pressure up to 15,000 psi. Accuracy is specified as 1/2% of span.
Wetted parts include Type 316 stainless steel tubes and sockets with threaded restrictors. Standard filling medium is Glycerine (rated +20°F to +150°F), while Silicone is available by special order for -40°F to +150°F service.
A safety warning notes that misuse may cause explosion or personal injury; users are advised to read ANSI B40.1 before installation. Glycerine can react with strong oxidizing agents such as chlorine, nitric acid, and hydrogen peroxide, potentially causing an explosion. Consult the factory for proper filling media in hazardous service.
Configuration Options
The series supports various mounting configurations to accommodate different installation requirements:
- Direct Mounting: Standard 1/4" NPT bottom connection.
- Panels and Walls: Back Flange mounting is available as Series LF602BF.
The gauge features a white aluminum dial with black and red markings, a clear tempered glass window, and a micro-adjustable black anodized aluminum pointer. The internal movement is stainless steel rotary type with bushings.
Key Product Differences
Differentiation within the broader Weiss industrial gauge family includes case size (2 1/2", 4", or 6"), ring style (crimped vs. bayonet), and filling status (liquid-filled LF series vs. non-filled NF series). The Series LF602 specifically denotes a liquid-filled, 6" stainless steel unit with a bayonet lock ring.
Accuracy varies by model family: the 2 1/2" crimped-ring models (LF251/LF252) offer ±1.6% of span; 4" and larger liquid-filled models generally provide 1% or 1/2% accuracy depending on construction, with Series LF602 specified at 1/2% of span.
