When using normal industrial thermometers in cooling applications, the thermometer housing cools down considerably due to the good thermal conductivity of the immersion tube and the aluminium casing. In case of high humidity, condensation may form on the casing. This effect can be avoided by using a thermometer with a condensation barrier.
» For use in refrigeration applications
» Prevents condensation on the thermometer casing
» As a side effect, the 50mm long condensation barrier allows the bridging of thick pipe insulation
» Lifetime warranty (except for broken glass and improper installation)
» Completely without electrical auxiliary power
» Available as type 291 (straight) and 292 (90° angled)
CASING
Nominal size 150 mm, aluminium, V-shaped, smoothly polished on all sides, anodised in brass colour, numbers of the display range printed in black on the right-hand side of the scale under the anodised layer.
THERMOMETRIC FILLING
In standard version from -30 to 50 °C blue thermometric liquid ("Fü").
IMMERSION TUBE
Made of brass as a standard. Stainless steel on request. The diameter of the immersion tube type "B" is Ø 10 mm; wall thickness 1 mm.
CONDENSATION BARRIER
The length of the condensation barrier is 50 mm. As a side effect, this distance between the immersion tube nipple and the thermometer casing allows thick tube insulation to be bridged.
