Product Description

Flanged Bimetallic Thermometer with Thermowell is robust temperature measurement system for harsh industrial settings, combining a dial thermometer (using a bimetal coil) with a protective, flange-mounted thermowell that shields the sensor from high pressure, heat, and corrosive fluids, allowing for safe insertion and removal without shutting down the process

. The flanged connection ensures secure mounting onto pipes or vessels, while the thermowell's design (often stainless steel) protects the thermometer's sensing element, making it ideal for chemical, oil & gas, and power industries.

Components & Function

Bimetallic Thermometer: Uses a strip of two bonded metals that bend with temperature changes, moving a pointer on a dial to indicate temperature.
Thermowell: A sealed, protective tube that isolates the thermometer from the process medium, allowing the sensor to "feel" the temperature through the thermowell's wall.
Flange: A flat, circular fitting that attaches securely to a matching flange on a pipe or tank, providing a leak-tight, high-pressure seal.

Key Features & Benefits

Protection: Shields the thermometer from corrosive media, high velocity, vibration, and extreme temperatures.
Easy Maintenance: Allows for quick replacement or calibration of the thermometer without draining the system.
Robust Construction: Typically made from stainless steel (like 316L) for durability.
Versatile Mounting: Flanged connections come in various sizes (1", 1.5", 2") and pressure ratings (150#, 300#, etc.) for different applications.

Common Applications

Chemical processing plants
Petrochemical industries
Oil and gas pipelines
Power generation facilities
Shipbuilding

Selection Considerations

Flange Type: Raised Face (RF), Flat Face (FF), or Ring Type Joint (RTJ).
Flange Rating: 150#, 300#, 600#, etc., matching the system's pressure.
Thermowell Design: Solid drilled or fabricated, with appropriate length and diameter for the process.
Material: Stainless steel (304, 316) is common, but other alloys are used for extreme corrosives.
