Description
Endress+Hauser TT151: Robust Protection for Sensors
The Endress+Hauser TT151: Robust Protection for Sensors is a high-quality thermowell manufactured from solid barstock, adhering to industry standards such as DIN 43772, ASME B40.9, and NAMUR NE 170, or available as a universal custom configuration. This essential component provides superior protection for temperature sensors against the physical and chemical stresses encountered in demanding process lines or vessels. Its robust construction ensures safe and accurate temperature measurements, even under challenging conditions, making it an indispensable part of any reliable process instrumentation setup.
Shields Sensors from Harsh Environments
The TT151 thermowell shields sensors from harsh environments, a critical function for maintaining measurement accuracy and extending sensor lifespan. Designed for universal use, it provides a formidable barrier against corrosive media, abrasive particles, and high pressures, with capabilities of up to 500 bar (7252 psi) depending on the configuration. This protection is vital in industries where processes involve aggressive chemicals or extreme operating conditions. The ability to select from a wide range of medium contact materials further enhances its suitability for specific, challenging applications.
Modular Configuration for Process Needs
Modular configuration for process needs is a key advantage of the Endress+Hauser TT151 thermowell. Users can select from a broad spectrum of dimensions, materials, and process connections, including threaded, weld-in, and flanged options according to ASME, EN, or ISO standards. The extension, immersion length, and total length can be precisely chosen to match specific process requirements. Additionally, the availability of straight, tapered, or stepped tip shapes allows for optimization based on flow conditions and measurement point needs, ensuring a perfect fit for any application.
Industry Standard Thermowell for Measurement
The TT151 serves as an industry standard thermowell for measurement, manufactured from round barstock for exceptional durability and performance. Its design ensures that temperature sensors are shielded from mechanical stress and corrosive effects, allowing for reliable data acquisition even in high-velocity applications when configured with the helical iTHERM TwistWell design. This industrial-grade protection is crucial for maintaining the integrity of temperature readings in critical industrial processes where precision and consistency are paramount.
Protecting and Ensuring Sensor Accuracy
Protecting and ensuring sensor accuracy is the core purpose of the TT151 thermowell. By preventing direct contact between the process medium and the temperature sensor, it safeguards the sensor from damage and contamination. This protection is essential for applications involving high pressures, extreme temperatures (ranging from -200 °C to 1100 °C, depending on configuration), and corrosive substances. The thermowell’s robust design, coupled with appropriate material selection, guarantees that the sensor remains accurate and functional over its intended service life.
Facilitating Easier Maintenance and Recalibration
The Endress+Hauser TT151 thermowell facilitates easier maintenance and recalibration, a significant operational benefit. Its design allows for the replacement or recalibration of the temperature sensor without the need to interrupt the process or drain the system. This capability minimizes downtime and associated costs, ensuring continuous operation and maintaining productivity. The ability to access and service the sensor easily streamlines maintenance procedures, contributing to the overall efficiency and cost-effectiveness of the process.
