Weiss Case Mount Gauge | 4CTN-400PB | 4″ Dial | 0-400 PSI/BAR
Product Description
The 4CTN-400PB is part of the specialized Weiss CTN series. The “CTN” designation identifies this as a Stainless Steel Case with a Narrow Front Flange, engineered for a modern, recessed installation into equipment panels where space between instruments may be limited. This model features a 4-inch (100 mm) dial with a dual scale of 0-400 PSI and 0-28 BAR.
In the UAE market, the 400 PSI range is a standard requirement for high-pressure applications, including fire protection headers, high-rise building booster sets, and industrial process monitoring in Dubai and Abu Dhabi. The polished stainless steel case provides superior protection against the high humidity and corrosive saline air found in Middle Eastern coastal regions. Equipped with a 1/4″ NPT Center Back Mount (CBM) connection, it ensures a clean, professional flush-fit installation.
Key Features
- Narrow Flange Design: The “CTN” narrow flange offers a compact and clean aesthetic, allowing for closer mounting of multiple gauges on a single control panel.
- Large 4″ High-Visibility Dial: Provides an oversized viewing area, ensuring pressure readings are clear and easy to read from a distance in large mechanical rooms.
- Stainless Steel Durability: Constructed from 304 Stainless Steel for enhanced longevity and rust resistance in humid environments.
- Dual Scale (PSI/BAR): Simultaneously displays pressure in both imperial and metric units, satisfying international engineering specifications in the UAE.
- Precision Brass internals: Utilizes a high-grade brass Bourdon tube and socket for consistent performance with non-corrosive media like air and water.

Frequently Asked Questions
- Q: Can this gauge be used for chilled water systems?
- A: Yes, the 400 PSI range is ideal for high-pressure chilled water lines, particularly in high-rise towers across Dubai and Abu Dhabi where static head pressure is significant.
- Q: What is the benefit of the Center Back Mount (CBM)?
- A: The CBM configuration allows all piping and connections to remain hidden behind the control panel, leaving only the clean dial face visible to the operator.
- Q: Is this gauge liquid-filled?
- A: This is a “Dry” gauge. If your panel is subject to heavy mechanical vibration or rapid pressure pulses, a liquid-filled (LF) version should be used to protect the internal movement.
