Gas expansion thermometer Type series FN….

Product catalog summary

Application Area: The gas expansion thermometer is suitable for use in shipping, machinery construction, chemical and petrochemical industries, and general process technology. It is designed for outdoor use and aggressive environments, with options for liquid damping in extreme conditions.

Features: The thermometer features a high-quality stainless steel case with a bayonet ring, available in sizes NS 100 and NS 160, and offers a degree of protection IP 66. It supports nominal temperature ranges from -40 °C to 700 °C, with further ranges available upon request. The device includes a micro-adjusting pointer for indication correction and can be equipped with various process connections and temperature detecting elements of different diameters.

Options: Available options include explosion protection (ATEX), calibration certificates, and electronic angle-of-rotation sensors. The thermometer can also be supplied with a liquid-filled case for additional damping.

Technical Data: The thermometer's construction includes a stainless steel case with a non-splintering laminated glass window. It uses a Bourdon tube as the measuring element, filled with noble gas, and offers an accuracy class of 1.0 per EN 13190. The device can operate in ambient temperatures as specified by EN 13190, with storage and transport temperatures ranging from -20 °C to 60 °C.

Process Connection and Measuring Element: The thermometer offers rigid temperature detecting elements with bottom or center back connections, and an adjustable angle stem. The measuring element is a Bourdon tube, and the temperature sensor is available in diameters of 6, 8, and ≥ 10 mm.

Nominal Range and Accuracy: The thermometer supports nominal ranges from -40 °C to 700 °C, with measuring spans of ≥ 60 °C. It adheres to accuracy class 1.0 per EN 13190.

Tests and Certificates: The thermometer is available with explosion protection certification (ATEX) and can be supplied with an EAC declaration and a certificate of measuring equipment for the Russian Federation.

Instructions for Use: The loading capacity of the temperature detecting element depends on media, media pressure, media temperature, flow velocity, insertion length, and material. A technical examination and the use of a separate thermowell may be necessary.

Dimensions: Detailed dimensions for bottom and center back connections, as well as adjustable angle stems, are provided, with specific measurements for different nominal sizes and ranges.

Order Details: The document provides a comprehensive list of order codes for different configurations, including case design, connection type, and additional features such as Ex-protection and calibration certificates.
