  • Skydrol Gauge

    3D Instruments

    Skydrol gauges are specially designed for use with a corrosive hydraulic fluid, namely Skydrol. 3D Skydrol gauges are designed specially to meet the challenging applicational requirements - specifically being designed to resist the effects of this corrosive hydraulic media. Nylon or stainless steel cases are fitted with glass crystals, and the stainless steel dials are done with a special Skydrol-resistant epoxy paint.

  • Precision Test Gauge

    3D Instruments

    The best Precision Test Gauge for your high accuracy test/calibration requirements. The 3D Instruments Precision Test Gauge is certified for industrial and laboratory pressure transfer measurement in the U.S. and worldwide.Incorporating 3D Instruments' well known expertise in test gauge design and application, the Precision Test Gauge provides unsurpassed long term accuracy.

  • Pressure Gauge

    Series 34 - 3D Instruments

    3D Instruments' new Series 34 direct drive pressure gauges provide that vital check even in the worst applications. You know the ones... the applications that result in pressure gauges with off-zero pointers, missing or broken pointers, or worn pressure systems. Typically, these problems are caused by vibration or pulsation.

  • Pressure Gauge

    Series 25 - 3D Instruments

    The Series 25 Accu-Drive pressure gauges incorporate the 3D Instruments signature "direct drive difference" Inconel helical bourdon tube system. The "direct drive technology" concept couples the bourdon tube directly to the shaft-pointer, thereby streamlining the design and reducing the number of moving parts from approximately twelve down to one!! Thirty years of industrial application have proven that this design is vastly superior to the C-bourdon tube/movement system incorporated in the traditional pressure gauges...especially for vibration and pulsation!!

  • Pressure Volume Controller

    3D Instruments

    The 3D variable volume pressure controller is available for calibration applications of 0-1,000 psi in absolute or gauge pressure. The V-1R functions as highly sensitive vernier controller with outstanding adjustment sensitivity of .0005 psi. Utilizing the principle of expansion or compression of gas by the displacement of a piston, it can generate up to 50 psi in a static system without requiring an outside pressure source. The pressure volume controller consist of a volume chamber and an internal piston assembly. Piston movement within the chamber increases or decreases the volume of the system depending on the direction of the piston movement. In a closed system, where trapped gas has no leak path, any volume change will result directly in a change of pressure. The pressure change generated by a given amount of piston travel is proportional to the change in volume as compared to the total system volume. The V-1R can also be used without a compressed air source for the generation of positive pressure below 50 psi as well as vacuum. The high resolution of this unit, combined with the ability to generate pressure, makes it the ideal choice for both low pressure calibration and test applications.

  • Stainless Steel Pressure Gauge

    3D Instruments

    3D Instruments' stainless steel pressure gauges are specially designed to meet the requirements of demanding pressure monitoring applications. Built to resist the effects of potentially challenging ambient environments, as well as the effects of corrosive process media, 3D's Accu-Drive stainless steel gauges incorporate our signature Direct Drive helical Inconel bourdon tube system.

  • Filled System Thermometers

    3D Instruments

    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.

  • Switch Gauge

    3D Instruments

    The Accu-Switch series of pressure Switch Gauges from 3D Instruments offers a new standard for a mechanical pressure gauge with high/low switch contacts. The long life, gold plated switch contacts can be wired directly to electrical circuits to provide for operational alarms or can be used to "stop/start" a variety of low amperage electrical equipment...pumps, valves, motors, etc. The Accu-Switch gauge pointer acts as both a pressure indicator and as a switch pole which completes a circuit when it comes in contact with one of the field-adjustable limit contacts. Utilizing our unique helical bourdon "direct drive" pressure measurement technology, the antiquated C-bourdon tube utilized in most conventional pressure gauges is eliminated. Additionally, the gearing, linkages, levers and springs required to generate pointer movement in the conventional pressure gauge, which are highly prone to wear and premature failure in high vibration and pulsation applications, are also eliminated!!

  • Hand-held Pressure Generator

    3D Instruments

    Portable pressure pump source used with a pressure gauge for calibration in the field. Calibrate a variety of pressure devices, i.e., Pressure Switches, Gauges, Differential Pressure Meters, etc.
