Weiss Bimetal Dial Thermometer | 5VBM6/130 | 5″ Dial | 6″ Stem
Product Description
The 5VBM6/130 is engineered for industrial applications where temperature must be monitored clearly from a distance. The “5VBM” designation identifies this as a 5-inch (125 mm) Dial thermometer with a Vertical (Bottom) Mount connection. This vertical orientation is ideal for mounting on top of horizontal pipes, ensuring the dial is upright and easy for operators in Dubai and Abu Dhabi plant rooms to read.
This model features a range of 30 to 130°F (0 to 55°C), which is specifically optimized for Chilled Water (CHW) and cooling tower applications. The narrow range allows for high resolution, making it easy to detect even small temperature shifts in the cooling loop. The 6-inch (150 mm) stem provides deep immersion to bypass thick pipe insulation and capture the true temperature of the fluid flow.
Key Features
- High-Visibility 5″ Dial: The oversized display with bold black markings on a white background allows for easy reading from across a large mechanical room.
- 6″ Industrial Stem: Specifically designed for mid-to-large diameter pipelines, ensuring the bimetal sensor reaches the core of the fluid stream.
- 304 Stainless Steel Construction: Both the case and the stem offer superior resistance to rust and corrosion in the high-humidity environments of the Middle East.
- Hermetically Sealed: The case is vacuum-sealed to prevent internal fogging and moisture ingress, a critical feature for chilled water applications where condensation is common.
- External Reset: Includes an easy-to-access calibration screw on the back of the case for simple field adjustment to maintain accuracy.

Frequently Asked Questions
- Q: Why use a 5″ dial instead of the standard 3″ dial?
- A: In large district cooling plants or high-rise mechanical floors, thermometers are often mounted high up. A 5″ 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, dust, 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 leaks and allow for maintenance without system shutdown.
