Vapour Filled System
(KTG31)

Temperature Gauge

Kains Vapour filled temperature gauge works on ‘vapour pressure difference due to temperature coefficient’ theory.   Kains uses a ‘pressurised gas chamber’ as a temperature sensor. When the chamber or bulb is get heated, the vapour pressure varies. The expansion or contraction of the vapour due to temperature is converted in to temperature reading. The pre formed bourdon tube displaces marginally due to pressure variation. The displacement is then calculated for the rotation of a sector mechanism @ 270 Deg angle.  The read pointer connected to the pinion rotates in accordance and  reads the temperature value marked on the clear dial. Kains Manufacturers Vapour Thermometers with bottom and back direct mounting.   KTG 31 is manufactured for remote mounting with Stainless Steel 304 case and bezel and Stainless steel 316 Bulb, stem and process connection. Kains manufactured temperature gauges can be used for general industrial temperate measurement in industries like chemical, petrol chemical, gas and oil, hydraulics and other machine building, food and pharmaceutical etc...
