Overview

Armored RTD with Waterproof junction box is a kind of temperature sensor. It has smaller diameter, better seismic resistance, and is easy to bend than fabricated platinum resistance. It is very suitable for installation where fabricated platinum resistance cannot be installed. The armored thermal resistance produced by our factory uses imported platinum resistance temperature measuring elements. Therefore, it has the advantages of sensitivity, fast thermal response time, stable quality, and long service life.

The outer protective sleeve of Armored RTD with Waterproof junction box is made of stainless steel and filled with insulator of high-density oxidation substances. Therefore, it has strong anti pollution performance and excellent mechanical strength, and is suitable for installation in harsh environments. The armored platinum resistance can be used to measure the temperature in the range of - 200~500 ℃, and can be directly connected to the secondary instrument with copper wire. Because of its good electrical output characteristics, it can provide temperature change input signals for displays, recorders, regulators, scanners, data recorders and computers, which shall comply with JB/T8622-1997 standard.

Working principle of Armored RTD with Waterproof junction box

the resistance of platinum resistance wire changes with temperature. The display instrument will indicate the temperature value corresponding to the resistance value generated by the platinum resistance.

Features of Armored RTD with Waterproof junction box
·Less thermal response time, reducing dynamic error;
·Small diameter, unlimited length;
·High measurement accuracy;
·Imported thin film resistance element, reliable and stable performance;
