Displacement sensors handle ultra-high temperature
A
Sensors UK product story

Jan 20, 2003
It used to be almost impossible to accurately measure mechanical movement or displacement, without contact, on targets operating at up to 600C.
Until the new VG series sensors were made available by Sensors UK, it was thought near impossible to accurately measure mechanical movement or displacement, without contact, on targets operating at up to 600C.
Many applications exist where measurements must be made in this hostile environment.
These include power generation, molten metal level and roll distortion in the steel industry, gas turbine radial vibration, air heater gap, casting, the nuclear industry, as well as research projects.
The VG series are eddy current proximity sensors, with the probe manufactured in Pallasil.
This new material can withstand continuous operation at these elevated temperatures, and offers a stable electrical resistance across a wide temperature spectrum.
This probe is connected by an armoured cable to the conditioning electronics which are housed within a specially protected industrial enclosure.
Measurements of up to 25,000um can be made, with temperature ratings of 250, 400 and 600C, and a proportional 0-5V DC output signal is given.
Power required is 115V AC.
