TNF - Gas-Filled Capillary Thermometer

KOBOLD TNF gas-filled capillary thermometers are highly versatile and rugged gas-filled thermometers for industrial applications. 

The TNF is available as a simple temperature indicating device or as a controller with one to four adjustable switch points. The sensing bulb is filled with inert nitrogen. 

Temperature changes at the bulb result in a change in nitrogen pressure, which is sensed in the indicating mechanism and displayed as a change in temperature. 

Capillaries are available in stainless steel and stainless steel with a flexible stainless steel armor sheath. 

A selection of indicator housings is offered with wall-mounting brackets or panel-mount flanges. 

This thermometer can be ordered with a variety of optional oil fillings for applications where high vibration is present. 

The TNF is also available with dial sizes ranging from 63 to 250mm (2.5" to 10").

A variety of fittings is available to suit almost any application.
