OIML R 133: 2002 (E) 5 3.4 Expansion chamber Enlargement at the upper end of the capillary to provide protection against possible bulb distension or breakage as a result of excessive liquid and gas pressures when a thermometer is exposed to a temperature greater than its working range. 1535 °C, eng Schmelz am Ëmbau-001.jpg 2,360 × 3,146; 5.04 MB. The following is the mechanism of operation for liquid-in-glass thermometers: Easy guide on how to make onion oil. A liquid in a glass tube (called a capillary) expands when heated and contracts when cooled. 3. The quality, stability, and accuracy vary considerably. Liquid in Glass Thermometer - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. The mercury thermometer is one example of liquid thermometers. Some ASTM committees are now discussing whether other types of thermometers, such as platinum resistance thermometers (PRTs), thermistors, or thermocouples, may be included as alternatives in a number of standards. 24" & 18" Precision Serialized Liquid In Glass Thermometer Precision Liquid-In-Glass Thermometers. The boiling point of methyl alcohol is 64.65 °C, and its melting point is -97.78 °C. $6.41 $ --Item# GT-738640 . 0000005676 00000 n Meteorological Instrument Center Japan MeteorologicaJapan Meteorological Agencyl Agency Liquid in glass thermometer How to read the value; The interval of line: 0.2°C Read the value in units of 0.1°C. $192.72 $ --Item# GT-60201. 0000002723 00000 n A LiG thermometer, by definition, is a glass capillary tube with a liquid-filled bulb at one end. When the bulb contacts a hot object, the liquid in it expands and rises in the tube. Water is known to freeze at 0°C and to boil at 100°C at an atmospheric pressure of 1 atm. The liquid in glass thermometer has a glass bulb attached to a sealed glass tube (also called the stem or capillary tube).

Liquid in Glass Thermometers Thermco’s Precision Liquid In Glass Thermometers are manufactured with the finest glass manufactured under ISO2001 guidelines. 2006-09-06 12 59 43 Cotton Region Shelter with door open (center) and Nimbus electronic temperature sensor (left).jpg 2,816 × 2,112; 2.04 MB. H�b```f``id`a``_��ǀ |@1�hb`P���a�aQ!�p[�4�l���T�����j�WS��&. A calibrated scale can then be used to read off the respective temperature that led to the corresponding thermal expansion. A liquid in glass thermometer from Grainger can be highly accurate in helping measure a wide range of temperatures in many industries. When it is hot, the liquid inside the thermometer will expand and rise in the tube. The Liquid-in-Glass Thermometer is a type of a thermometer used to measure temperature. 2.2.2 Liquid-in-glass Thermometers A liquid-in-glass thermometer measures temperature based on the thermal expansion of mercury or spirit alcohol in a glass container. Liquid-in-glass thermometers (1) Applies only to the French text. The glass stem of a thermometer is thick and acts as a cylinder lens. 0000003340 00000 n A thermometer is calibrated by using two objects of known temperatures. The principle used to measure temperature is that of the apparent thermal expansion of the liquid. The commonest and best liquid is mercury. Introduction Construction . Quantity Price each; 1-4: $192.72: 5-9: $183.08 : 10-24: $179.23: 25-49: $171.52: 50-99: $167.67: 100+ $163.81: Qty. The main difference between partial and total immersion thermometers is the application in which they should be used. The range of a liquid-in-glass thermometer is limited by the liquid, by the glass, and by the construction. Some of the uses are process piping, tanks, pipelines in building construction, boilers and air ducts. Added to Your Shopping Cart. Point of reference i.e. According to British Standards, correctly calibrated, used and maintained liquid-in-glass thermometers can achieve a measurement uncertainty of ±0.01 °C in the range 0 to 100 °C, and a larger uncertainty outside this range: ±0.05 °C up to 200 or down to −40 °C, ±0.2 °C up to 450 or down to −80 °C.
