METALLIC PROTECTOR THERMOMETER WLG-11

Product Specification

The WLG-11 Metal-Sheathed Thermometer is a robust, industrial-grade temperature measurement instrument designed specifically to ensure reliable operation in marine, piping, boiler, and general industrial environments. It ingeniously combines a precision glass-tube thermometer with a durable metal protective sheath, offering both accurate temperature readings and robust physical protection against pressure, vibration, and corrosive media. Thanks to this unique combination, the thermometer serves as an ideal choice for direct installation on storage tanks, pipelines, and various types of equipment—applications where unprotected instruments would be highly susceptible to damage due to direct exposure to harsh operating conditions.
Constructed with a sturdy metal housing (typically brass, steel, or stainless steel), the WLG-11 features a pressure rating of up to 6.4 MPa, ensuring safe and stable operation within pressurized systems. To accommodate diverse installation requirements, the thermometer is available in various structural configurations, including straight, 90° angled, and 135° angled options. Its temperature-sensing medium can be selected as either mercury (suitable for high-temperature ranges) or a colored organic liquid (suitable for low-temperature ranges); coupled with clear, easy-to-read scale markings, this ensures that users can effortlessly and accurately obtain temperature data. Furthermore, the thermometer utilizes a threaded connection mechanism to facilitate a secure and leak-proof installation—a feature that has established it as a widely adopted temperature monitoring solution across marine vessels, industrial facilities, and various types of mechanical equipment.
