Manufacturer: 3D Instruments

Direct Drive Difference in Thermometers

The 3D thermometer is superior to other systems because it provides an evenly graduated scale without the use of a multiplying mechanism or delicate geared segments, pionions or hair springs. This results in a most rugged instrument suitable for installations which, by necessity, have severe vibration and shock.

Because of its "gearless" mechanism, the 3D thermometer has the following advantages as compared with conventional type thermometers.

1. Excellent stability.
2. Less trouble because of its simple mechanism.
3. More durability against vibration and shock.
4. Smoother movement of pointer action.
5. Better accuracy.
6. Greater sensitivity and faster response to changes in temperatures.

Standard Specifications

Case

Cases are black enameled cast aluminum with glass crystal and "O" ring seal.

Standard model is cas compensated. Dual capillary (case and line compensated) are also available.

Some models such as "AGNESS" have stainless steel case as standard.

Dial Face

Black numbers and divisions on White background. Black pointer standard.

White on black is available as an option.

Three dial sizes 3" (75mm), 4" (100mm), 6" (150mm), on most models.

Capillary

10 feet (3m) is standard length capillary for all Remote Reading Thermometers. Maximum length capillary is 33 feet for case compen-sated types, and 164 feet (50m) for Dual Capillary and Line Compensated types. The standard material of construction is stainless steel.

Bulbs

Liquid Filled Gauges have 10 mm (.393") diameter bulbs x 4" in length as standard, with a 1/2" NPT sliding union connection (bulb model - A). Gas Filled Gauges have 12 mm (.472") diameter bulbs x 4" in length, with 1/2" NPT sliding union connection (bulb model - A). 3/4" unions, fixed unions, and plain bulbs available as options.

Compensations

Bimetal compensator corrects for ambient temperature change. (case compensation is standard) Double lead compensator (consists of two bourdon tubes and capillary tubes) available if specified.
