Thank you for choosing a NIVELCO instrument.
1. APPLICATION
THERMOCONT TXP resistance thermometers with a drilled thermo-well case are used as temperature
measurement sensors in industrial process control, especially in the gas industry. The temperature sensors
are 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 ambient
temperature. The double pipe construction - including the inner and outer tube and well - meets the
mechanical and vibrational protection requirements. Process connection and electrical connection are
provided 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 housing
has a chain to prevent misplacing it. The Pt100 temperature sensor can be replaced without removing the
instrument from the process.
