TRERICE

Trerice is a manufacturer of temperature and pressure instrumentation with a history dating to the early 20th century. The company is known for producing thermometers, thermowells, pressure gauges, and related accessories used in industrial process control, HVAC, and fluid handling systems. Trerice products are specified where direct indication of temperature or pressure is required, and where sensor protection and thermal coupling are necessary for accurate measurement. The line includes bimetal and digital thermometers, adjustable-angle and fixed-angle configurations, threaded and flanged thermowells, and heat transfer compounds. 3G Electric supplies Trerice instrumentation globally, with stock including digital thermometers, thermowells, and heat compounds. The digital thermometers in the Trerice line feature adjustable-angle heads, water-resistant construction, and stem lengths from 3.5 to 6 inches. Temperature ranges cover -50°F to 300°F (-46°C to 150°C) or -40°F to 300°F (-40°C to 150°C), with accuracy of ±1% or ±1°F, whichever is greater. Thread connections include 1/2-inch NPT and 1 1/4-inch UNEF, allowing installation in a variety of pipe and vessel sizes. These instruments are used in process piping, tanks, and HVAC equipment where local temperature indication is needed. Trerice thermowells are available in stepped-shank threaded designs, constructed from stainless steel. They are rated for 600°F maximum temperature and 630 psi at 70°F. Insertion lengths include 1 3/4 inches and 2 1/2 inches, with compatibility for 3 1/2-inch stem length sensors. Thermowells protect temperature sensors from corrosive fluids, high velocities, and mechanical damage, and allow sensor removal without process shutdown.

Frequently asked questions

Common questions about TRERICE from 3G Electric.

What temperature range do Trerice adjustable-angle digital thermometers cover?

Trerice adjustable-angle digital thermometers are available in two temperature ranges: -50°F to 300°F (-46°C to 150°C) and -40°F to 300°F (-40°C to 150°C). Accuracy is ±1% or ±1°F, whichever is greater. These thermometers feature water-resistant construction and adjustable-angle heads for readability in various mounting positions. Stem lengths include 3.5 inches, 4 inches, and 6 inches. Thread connections are 1/2-inch NPT or 1 1/4-inch UNEF, depending on the model. They are suitable for direct installation in process piping, tanks, and HVAC equipment where local temperature indication is required.

What are the pressure and temperature ratings for Trerice stepped-shank threaded thermowells?

Trerice stepped-shank threaded thermowells are rated for a maximum temperature of 600°F and 630 psi at 70°F. They are constructed from stainless steel. Insertion lengths include 1 3/4 inches and 2 1/2 inches, and they accommodate sensors with a 3 1/2-inch stem length. These thermowells protect temperature sensors from corrosive fluids, high flow velocities, and mechanical impact. The stepped-shank design reduces stress concentrations and allows for sensor removal without shutting down the process. They are used in industrial piping and vessels where sensor protection is necessary.

How does Trerice heat transfer compound improve temperature measurement?

Trerice heat transfer compound, such as the 107-0001 white paste, is applied between the temperature sensor and the thermowell bore. It fills microscopic air gaps that would otherwise act as insulation, improving thermal conductivity and reducing response time. This results in more accurate temperature readings, especially in applications where fast response is critical. The compound is supplied in a 1 oz tube and is suitable for HVAC and industrial heat transfer applications. It is compatible with common sensor and thermowell materials. Regular reapplication may be needed depending on operating conditions and maintenance schedules.

What thread sizes are available for Trerice digital thermometers?

Trerice digital thermometers are offered with 1/2-inch NPT or 1 1/4-inch UNEF thread connections. The 1/2-inch NPT models are standard for many pipe installations, while the 1 1/4-inch UNEF models are used in applications requiring a larger thread. Both thread types are available with adjustable-angle heads and water-resistant construction. Stem lengths vary from 3.5 to 6 inches. When selecting a thermometer, verify the thread type and size match the installation point. Adapters may be used to convert between thread types if necessary, but direct matching is recommended for proper sealing and stability.

Can Trerice thermowells be used with digital thermometers?

Yes, Trerice thermowells are designed to accept temperature sensors, including digital thermometers with compatible stem lengths. The thermowells have insertion lengths of 1 3/4 inches or 2 1/2 inches and accommodate sensors with a 3 1/2-inch stem length. When pairing a thermowell with a digital thermometer, ensure the sensor stem length matches the thermowell's insertion length and that the thread connections are compatible. Using a thermowell allows sensor replacement without process shutdown and protects the sensor from harsh conditions. Heat transfer compound should be used to maintain accurate readings.

What materials are Trerice thermowells made from?

Trerice stepped-shank threaded thermowells are constructed from stainless steel. This material provides corrosion resistance and mechanical strength for use in industrial environments. The specific grade of stainless steel is not detailed in the provided specifications, but standard Trerice thermowells are typically made from 316 stainless steel. Stainless steel is suitable for many process fluids, including water, steam, oils, and mild chemicals. For highly corrosive applications, alternative materials may be required. Consult the manufacturer's literature for specific material compatibility and temperature derating information.
