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!!
The Accu-Switch Switch Gauge is designed to provide superior performance in the harshest of process environments! It is housed in a robust weather-resistant 4.5" ABS case and features corrosion resistant materials throughout: ABS case, Inconel bourdon tube and stainless steel process connection and hardware. The Accu-Switch Switch Gauge incorporates some very revolutionary design concepts...from our unique "Dyna-Mount" flange/fitting system, whereby the process connection fitting can be adjusted from "bottom to back" configuration in the field with only the use of a screwdriver to the external zero adjustment to minimize potential maintenance.
The combination of sophisticated pressure measurement technology, robust design and long life switch contacts makes the Accu-switch from 3D Instruments the ideal choice for your demanding pressure monitoring, alarm or switching applications.
