Product details
Weiss Pressure Gauge | TL35-P200 | 3.5″ Dial | 0-200 PSI/BAR
Product Description
The TL35-P200 belongs to the Weiss Trade Line (TL) series, which is specifically engineered for the construction and HVAC markets. The “TL35” designation identifies this as a 3.5-inch (90 mm) Dial gauge. This intermediate size is highly valued in Dubai and Abu Dhabi for being easier to read than standard 2.5″ gauges while fitting into tighter spaces where a 4.5″ gauge would be impractical.
This model features a pressure range of 0 to 200 PSI (0 to 14 BAR). This range is the standard specification for Domestic Water Booster Systems and Chilled Water (CHW) supply lines in multi-story buildings, providing accurate resolution for systems typically operating between 80 and 150 PSI. The gauge is housed in a rugged black-finished steel case with a clear, friction-fit window.
Key Features
- Intermediate 3.5″ High-Contrast Dial: Offers improved visibility over small utility gauges, featuring a clean white face with bold black (PSI) and red (BAR) markings.
- Dual Scale (PSI/BAR): Displays pressure in both imperial and metric units, satisfying the requirements of international consultants and local UAE building codes.
- Precision Bronze Internals: Equipped with a high-quality phosphor bronze Bourdon tube and a precision brass movement for consistent accuracy and long-term reliability.
- Durable Construction: The black-painted steel case provides strong protection against mechanical impact and environmental dust in plant room conditions.
- Standard Connection: Features a 1/4″ NPT brass connection at the bottom, allowing for easy installation into standard manifolds and valve sets.

Frequently Asked Questions
- Q: Is a 3.5″ dial better than a 2.5″ dial for pump skids?
- A: Pump skids often have significant vibration and equipment crowded together. The 3.5″ dial allows an operator to monitor the discharge pressure more easily from a standing position.
- Q: Can this be used for compressed air?
- A: It is a common upgrade for industrial air compressors and headers where a more durable, easier-to-read gauge is required.
- Q: Does this gauge require a siphon?
- A: Only if used for steam service. For water, air, or oil, it can be mounted directly to the system pipe or through an isolation valve.
