Resistance temperature probe for Ex areas, threaded process fit

GTF102-EX

Resistance temperature probe for Ex areas with Pt100 or Pt1000 4-wire elements, fixed cable, G 1/2"A standard thread, 100 mm x 6 mm probe tube and measuring ranges up to -200 ... +600 °C.

Introduction

Temperature measurement in explosive atmospheres needs a probe that matches both the Ex zone and the process connection. This resistance temperature probe is designed as a compact threaded insertion sensor for hazardous industrial areas and 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 102-Ex design includes a G 1/2"A thread, 100 mm probe length and 6 mm probe tube diameter. Silicone, PVC and Teflon cable options are listed for Pt100 and Pt1000 versions, while configurable tube diameters, neck tube designs and thread types support different installation requirements.
