Introduction

A correctly matched thermowell or threaded nipple helps adapt a Pt100 bayonet sensor to the process connection. The STH range provides thermowells for Pt100 sensors in 1.4571 stainless steel, with internal diameters from 4 to 11 mm and pressure ratings of 100 or 500 bar.
 
Different STH designs support sensors with G½" thread or clamp-ring mounting. Depending on the selected shape, the press ring is made from 1.4571 stainless steel or PTFE. Special dimensions and designs are available for specific installation requirements.
 
The GWN range provides threaded nipples for PTM sensors with a 12.2 mm bayonet connection and 6 mm sensor diameter. Open and closed versions are available with M10x1 connection. The closed version also supports a defined sensor length, allowing the adapter to be matched to the installation.
