Weiss Pressure Gauge | TL45-P160 | 4.5″ Dial | 0-160 PSI/kPa
Product Description
The TL45-P160 belongs to the high-visibility Weiss Trade Line (TL) series. The “TL45” designation identifies this as a 4.5-inch (115 mm) Dial gauge, providing a significantly larger viewing area than standard utility gauges. This makes it ideal for installation in high-ceiling mechanical rooms or on large equipment skids in Dubai and Abu Dhabi where gauges must be read from a distance.
This model features a pressure range of 0 to 160 PSI (0 to 1100 kPa). This specific range is the industry standard for Domestic Water Booster Pumps and Chilled Water (CHW) supply lines, as it provides high resolution for systems typically operating between 60 and 120 PSI. The gauge is housed in a rugged black-finished drawn steel case with a clear, impact-resistant polycarbonate window.
Key Features
- Oversized 4.5″ High-Visibility Dial: Features a clean white face with bold black graduations, allowing for precise pressure monitoring from a distance.
- Dual Scale (PSI/kPa): Displays pressure in both imperial (PSI) and metric (kPa) units, complying with international building standards and project specifications in the UAE.
- Precision Bronze Internals: Equipped with a heavy-duty phosphor bronze Bourdon tube and a precision brass movement for consistent accuracy and response.
- Durable Construction: The black steel case and friction-fit polycarbonate window provide excellent protection against mechanical shock and dust ingress.
- Standard Connection: Features a 1/4″ NPT brass socket, making it compatible with most standard industrial piping and manifolds.

Frequently Asked Questions
- Q: Why use a 4.5″ dial instead of a 2.5″ dial?
- A: In large mechanical rooms, gauges are often mounted 2-3 meters high. A 4.5″ dial like the TL45 is necessary for the operator to read the exact pressure safely from the floor.
- Q: Can this be used for steam service?
- A: For steam, it is mandatory to use this gauge with a coil-type siphon (pigtail) to prevent high-temperature steam from damaging the internal bronze Bourdon tube.
- Q: Is this gauge liquid-filled?
- A: No, the TL45 is a “dry” gauge. If your application has high vibration (e.g., near a reciprocating compressor), you should consider the Weiss LF series liquid-filled gauges.
