Weiss Bimetal Dial Thermometer | 7V35 | 3″ Dial | 5″ Stem
Product Description
The 7V35 is part of the 7-series bimetal thermometers, known for their durable all-stainless steel construction. The “7” identifies this as a 3-inch (75 mm) Dial model, while the “V” indicates a Vertical (Bottom) Mount configuration. This orientation is ideal for installation on the top of horizontal pipelines, ensuring the dial faces the operator upright for clear reading in Dubai and Abu Dhabi mechanical rooms.
This model features a wide temperature range of 30 to 300°F (0 to 150°C), making it suitable for a variety of high-temperature applications, including Domestic Hot Water (DHW), heating water, and low-pressure steam. The 5-inch (125 mm) stem provides a solid immersion depth for medium-diameter pipes, ensuring the sensor bypasses insulation to deliver a precise thermal reading.
Key Features
- Compact 3″ High-Visibility Dial: Features a high-contrast white face with bold black and red markings, allowing for quick and accurate temperature checks.
- 5″ Industrial Stem: Specifically sized for common pipeline diameters, providing reliable immersion for accurate thermal measurement.
- All-Stainless Steel Construction: Both the case and the stem are crafted from 304 Stainless Steel, offering superior resistance to the high humidity and corrosive air of the Middle East.
- Hermetically Sealed Case: Vacuum-sealed to prevent internal fogging and moisture ingress, ensuring the dial remains clear throughout its service life.
- External Recalibration: Includes an external reset screw on the back of the case, allowing for easy field calibration to maintain long-term precision.

Frequently Asked Questions
- Q: Can this thermometer be used for steam applications?
- A: Yes, the 300°F range is suitable for low-pressure steam. For high-pressure steam, a higher range (like 50-550°F) would be necessary.
- Q: Is the 5″ stem appropriate for insulated pipes?
- A: Yes, the 5″ length typically allows for 1.5 to 2 inches of insulation while still providing sufficient immersion into the fluid flow.
- Q: Does this include the thermowell?
- A: For pressurized applications, it must be installed in a 5″ Weiss Thermowell (typically model E5-35BS) to prevent leaks and allow for maintenance without shutdown.
