Thermometers

BULLETIN DT-1

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 pressuresare 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.

Introduction Duratemp Thermometers

Mercury FreeGas Filled

• NIOSH and OSHA compliance for mercury contaminationhazards. Protects personnel and processes from accidentalcontamination.

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 technicaladvancement 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 Navy’s rugged require-ments. Today’s Duratemp is a directoffshoot of the Navy thermometer,and incorporates in its design all the 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

02–Aluminum Hinged Ring–An alu-minum case with a durable epoxy finish.Designed specifically for panel mounting. Ahinged ring permits glass replacement andpointer adjustment. Available in 41⁄2,˝ 6˝ and81⁄2̋ sizes.

03–Aluminum Threaded Ring–A blackepoxy coated aluminum case, with excellentimpact resistance. Threaded ring permitspointer adjustment. Available in 41⁄2̋ and 6˝sizes.

04–Phenolic, Snap Ring–The phenoliccase construction is ideal for most ambientconditions. Flush or surface mounting. Snapring permits pointer adjustment. Available in41⁄2,˝ 6˝ and 81⁄2̋ sizes.

600H-45–Hermetically Sealed Case–This case is designed for moisture and dustapplications. Available in a 41⁄2̋ solid front phenolic turret case, lower connection.

600B–Stainless Steel DirectMounted–The direct reading thermometer(stainless steel case only) offers the sameunique features of the Duratemp remotereading thermometer for those critical appli-cations where only a direct connected instru-ment can be used. Available in 41⁄2̋ dial size,the direct reading thermometer unit featuresa linear, anti-parallax dial for excellent read-ability. The thermometer’s Everyangle har-

ness allows for a 360° rotationand stem turn of 180°, ensuringreadability in any installation.Ideal for low or high tempera-ture service or shock and vibra-tion conditions where a bimetalmay not be suitable.

Styles B01, B17 and B18 are bendableextensions with union connections. B01(12˝ bendable extension) is the standardDuratemp bulb style and is suitable for avariety of insertion lengths and laggingrequirements. B17 is a 18˝ bendableextension, B18 is a 24˝ bendable exten-sion. The union connection on all threestyles is pressure tight and can be freelymoved the entire length of the bendableportion. After installation, the bendableextension may be formed to suit theapplication.

Style B0313˝ plain bulb for applications used inopen tanks where pressures and veloci-ties are negligible.

Style B08The compression fitting fastens any-where along the armored line. This bulbstyle is well suited for insertion require-ments in excess of 131⁄2˝. The B08 styleis not a pressure tight connec-tion. A thermowell

is recommended for this style and for allbulb styles.

Product Selection Information

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 160°F (71°C). 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 permitsinstrument interchangeability or recalibration with-out shutting down the process.

CasesFive case styles and three different materials are 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 3⁄8˝diameter 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 the41⁄2˝ 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.
