Product Description

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.
