pressure is proportional to theabsolute temperature. To obtain ausable temperature span, elevatedworking pressures must be usedwhich frequently produce highstresses in the Bourdon tube.These high stresses reduce instru-ment life and may be hazardous.
The Duratemp thermometer on theother hand utilizes a combination ofinert gas and activated carboncalled a molecular sieve. This com-bination produces much lower inter-nal pressures than conventionalthermometers for the same temper-ature span. These lower pressures
are transmitted to a compact helicalBourdon tube. The Bourdon tubeconnects directly to the pointershaft thus eliminating the traditionalmovement assembly.
With this advantage the Duratempthermometer is able to provide longlife and sustained accuracy underthe most adverse shock and vibra-tion conditions.
The molecular sieve concept, uti-lized by Dresser in its Duratempthermometer, offers a host of fea-tures, functions and benefits thatmake it superior to any conventionalmechanical thermometer on themarket today.
Duratemp thermometers are avail-able through our extensive distribu-tor network and our manufacturingplant in Stratford, CT.

Mercury Free
Gas Filled NIOSH and OSHA compliance for mercury contamination
hazards. Protects personnel and processes from accidental
contamination.
No Head or Elevation Error Accurate readings are ensured even if the bulb is
mounted above or below the case.
Shock and Vibration ResistanceUnique Direct Drive Bourdon Tube
Gear and pinion movements are eliminated, result-ing in increased instrument life and reduced
replacement costs.
Silicone damped Bourdon tube eliminatesdamage from shock and vibration.
The Duratemp thermometer offersthe same outstanding quality andcraftsmanship which has character-ized all Ashcroft products since theintroduction of the Bourdon tube toAmerican industry in 1852.
Uncompromising standards havebeen established for materials andworkmanship. The finished productassures the user of superior durabil-ity and dependability.
All Duratemp thermometers useand actuation concept unique to thefield of temperature measurement,called a molecular sieve. Thisdesign represents a technical
advancement over conventional gasand mercury thermometers.
Research and development of amolecular sieve thermometer beganin 1964 when the US Navy askedthermometer manufacturers todevelop a remote thermometer thatwas both linear and mercury free. In1970 Dresser received Navyapproval on the molecular sievethermometer and for over a decadewas the only manufacturer to com-ply with the Navys rugged require-ments. Todays Duratemp is a directoffshoot of the Navy thermometer,and incorporates in its design allthe features found in the originalNavy design.
The superiority of a Duratemp ther-mometer is revealed by comparisonto conventional thermometry.Conventional gas thermometersoperate on the principlethat the absolute

600A Remote Mounted Duratemp
01Stainless Steel Case A high-impactresistant polished stainless steel case. A bay-
onet ring facilitates easy removal for glass
replacement and pointer adjustment. A
versatile case that enables surface or flushmounting. Available in 412 size.
02Aluminum Hinged RingAn alu-minum case with a durable epoxy finish.
Designed specifically for panel mounting. A
hinged ring permits glass replacement and
pointer adjustment. Available in 412, 6 and
812 sizes.
03Aluminum Threaded RingA blackepoxy coated aluminum case, with excellent
impact resistance. Threaded ring permits
pointer adjustment. Available in 412 and 6
sizes.
04Phenolic, Snap RingThe phenoliccase construction is ideal for most ambient
conditions. Flush or surface mounting. Snap
ring permits pointer adjustment. Available in
412, 6 and 812 sizes.
600H-45Hermetically Sealed CaseThis case is designed for moisture and dust
applications. Available in a 412 solid front
phenolic turret case, lower connection.
600B Stainless Steel DirectMountedThe direct reading thermometer(stainless steel case only) offers the same
unique features of the Duratemp remote
reading thermometer for those critical appli-
cations where only a direct connected instru-
ment can be used. Available in 412 dial size,
the direct reading thermometer unit features
a linear, anti-parallax dial for excellent read-
ability. The thermometers Everyangle har-
ness allows for a 360 rotationand stem turn of 180, ensuring
readability in any installation.
Ideal for low or high tempera-
ture service or shock and vibra-
tion conditions where a bimetal
may not be suitable.
Styles B01, B17 and B18 are bendable
extensions with union connections. B01
(12 bendable extension) is the standardDuratemp bulb style and is suitable for a
variety of insertion lengths and lagging
requirements. B17 is a 18 bendable
extension, B18 is a 24 bendable exten-
sion. The union connection on all three
styles is pressure tight and can be freely
moved the entire length of the bendable
portion. After installation, the bendable
extension may be formed to suit the
application.
Style B0313 plain bulb for applications used in
open tanks where pressures and veloci-ties are negligible.
Style B08The compression fitting fastens any-
where along the armored line. This bulb
style is well suited for insertion require-
ments in excess of 1312. The B08 style
is not a pressure tight connec-
tion. A thermowell
is recommended for this style and for all
bulb styles.
ARMOR STYLE

WarningDuratemp thermometers should be selected con-
sidering the media and the ambient operating con-ditions. Improper application can be detrimental tothe thermometer, cause failure and possible injuryor property damage.
The information contained in this bulletin is offeredas a guide in making the proper selection of an in-dustrial thermometer. Additional information is avail-able from Dresser Industries, Instrument Division.
Temperature RangesStandard Fahrenheit and Celsius ranges havebeen established to encompass all normal temper-
ature measurement requirements.
Operating ConditionsThe maximum case temperature should notexceed 160F (71C). The line should be laid sothat it will not be exposed to extreme temperaturessuch as alongside of steam pipes, ovens or otherheated surfaces.
ThermowellsThermowells must be used on any applicationwhere the bulb of the thermometer may be
exposed to pressure, corrosive fluids or high veloc-ity. Additionally, the use of a thermowell permits
instrument interchangeability or recalibration with-out shutting down the process.
CasesFive case styles and three different materialsare offered: aluminum alloy, stainless steel andphenolic. Each is designed with a removable ring.
BulbsThe bulb is manufactured of AISI 316 stainlesssteel. The sensing portion for all ranges is 38diameter by 3.
DialsAluminum dials have highly legible black markingson a white background. The Maxivision dial is a lin-ear anti-parallax dial for excellent readability in the412 and 6 sizes. The divisions and the pointer arein the same plane which allows readability fromany angle without parallax error.
WindowsThe standard window for the Duratemp thermome-ter is glass. Shatterproof glass and plastic discwindows are optional.
