KOBOLD TNS rigid stem thermometers are highly versatile and rugged gas-filled thermometers for industrial applications. The TNS 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 cause a change in nitrogen pressure, which is sensed in the indicating mechanism and displayed as a change in temperature. The stem thermometer is available with a variety of optional oil fillings for high-vibration applications, as well as with dial sizes ranging from 63 to 250mm (2.5" to 10") and with a variety of fittings to suit nearly any application.
