Product Inquiry

Introduction

Hazardous industrial areas need temperature measurement that fits the Ex zone and the process limits. This resistance temperature probe is designed as a compact insertion sensor for explosive atmospheres and is suitable for hard-to-access measuring points.
 
Pt100 and Pt1000 versions use sheathed resistance thermometer elements in 4-wire design. Depending on configuration, Pt100 versions cover -50 ... +100 °C without neck tube or -200 ... +600 °C with neck tube. Pt1000 versions with neck tube cover -70 ... +600 °C.
 
The standard GTF 101-Ex design uses a 100 mm probe length, 6 mm probe tube diameter and fixed connection cable. Silicone, PVC and Teflon cable options are listed for Pt100 and Pt1000 versions, while configurable probe tube diameters from 3 to 8 mm support different installation requirements.
