Weiss Case Mount Gauge | 4CTN-300PB | 4″ Dial | 0-300 PSI/BAR
Product Description
The 4CTN-300PB is part of the specialized Weiss CTN series. The “CTN” designation identifies this as a Stainless Steel Case with a Narrow Front Flange, specifically engineered for a modern, recessed installation into equipment panels where aesthetic clarity and space efficiency are required. This model features a 4-inch (100 mm) dial with a dual scale of 0-300 PSI and 0-20 BAR.
In the UAE market, the 300 PSI range is a highly versatile specification, ideal for monitoring main water distribution headers, high-rise booster sets, and industrial pneumatic systems in Dubai and Abu Dhabi. The polished stainless steel case provides excellent protection against high humidity and corrosive saline air, while the 1/4″ NPT Center Back Mount (CBM) ensures a clean, professional finish with all piping hidden behind the panel.
Key Features
- Narrow Flange Design: The “CTN” narrow flange allows for a compact and clean aesthetic, enabling multiple gauges to be mounted closely together on a single control panel.
- Large 4″ High-Visibility Dial: Features a high-contrast white face with bold black markings, ensuring accurate readings from a distance.
- Stainless Steel Durability: Constructed from 304 Stainless Steel for enhanced longevity and resistance to rust in humid mechanical rooms.
- Dual Scale (PSI/BAR): Simultaneously displays pressure in imperial and metric units, satisfying international engineering and safety standards.
- Precision Brass internals: Utilizes a high-grade brass Bourdon tube and socket for consistent performance with non-corrosive air and water.

Frequently Asked Questions
- Q: Is this gauge suitable for fire protection panels?
- A: Yes, the 300 PSI range and flush-mount narrow flange are ideal for fire pump controllers where space is limited but high visibility is mandatory.
- Q: What is the difference between CTN and CTS?
- A: Both are stainless steel panel gauges; however, the CTN has a slimmer flange (Narrow), whereas the CTS has a standard wide flange.
- Q: Can this be used for outdoor panels in the UAE?
- A: The stainless steel case handles humidity well, but for direct outdoor exposure to sand and salt, we recommend ensuring the panel itself is NEMA/IP rated to protect the gauge window.
