Product details
Weiss Bimetal Dial Thermometer | 5RBM6-0-130 | 5″ Dial | 6″ Stem
Product Description
The 5RBM6-0-130 is specifically engineered for industrial plant rooms where legibility from a distance is essential. The “5RBM” designation identifies this as a 5-inch (125 mm) Dial thermometer with a Rear (Center Back) Mount connection. This configuration is ideal for side-mounting on vertical pipelines or installation into storage tanks, ensuring the oversized dial faces the operator directly in Dubai and Abu Dhabi mechanical spaces.
This model features a temperature range of 0 to 130°F (-17 to 55°C), making it exceptionally well-suited for Chilled Water (CHW) and cooling tower applications. The 6-inch (150 mm) stem provides deep immersion to bypass standard pipe insulation and reach the heart of the fluid stream, ensuring a fast and accurate thermal response.
Key Features
- Oversized 5″ High-Visibility Dial: The massive display with high-contrast markings allows technicians to check critical cooling temperatures from across a large mechanical room.
- 6″ Industrial Stem: Specifically designed for mid-to-large diameter pipelines, providing optimal immersion for maximum thermal accuracy.
- Rear (Center Back) Mount: Provides a clean, flush-looking installation on the side of pipes or panels.
- 304 Stainless Steel Construction: Both the case and the stem offer superior resistance to corrosion and the humid, saline air of the Middle East.
- Hermetically Sealed Case: Vacuum-sealed to prevent internal fogging and moisture ingress, essential for maintaining clarity in chilled water applications where condensation is prevalent.
- External Reset: Features a calibration adjustment screw on the back of the case for easy field recalibration.

Frequently Asked Questions
- Q: Why use a 5-inch dial instead of the standard 3-inch?
- A: In large district cooling plants, thermometers are often mounted high up or in difficult-to-reach areas. A 5-inch dial ensures the operator can read the temperature safely from the floor.
- Q: Is this thermometer suitable for outdoor installation?
- A: The 304 Stainless Steel case and hermetic seal make it highly resistant to the UAE’s intense sunlight and humidity.
- Q: Does this require a thermowell?
- A: For pressurized piping, it must be installed in a 6″ Weiss Thermowell (typically model E6-35BS) to prevent system leaks and allow for maintenance without shutdown.
