txp171en22h03 ▪ 1 / 2Thank you for choosing a NIVELCO instrument.1. APPLICATIONTHERMOCONT TXP resistance thermometers with a drilled thermo-well case are used as temperaturemeasurement sensors in industrial process control, especially in the gas industry. The temperature sensorsare suitable for temperature measurement of various gaseous media inside pipelines, tanks, and furnaces.The heat-sink on the outer protective tube provides accurate measurement independently from the ambienttemperature. The double pipe construction - including the inner and outer tube and well - meets themechanical and vibrational protection requirements. Process connection and electrical connection areprovided as detailed below. The cable glands provide sealing for the cables.The outer protective tube is a drilled thermo-well case made from stainless steel. The cover of the housinghas a chain to prevent misplacing it. The Pt100 temperature sensor can be replaced without removing theinstrument from the process.2.
