Working Mechanism

  • It makes use of a sensor that can translate the pressure exerted on it into electrical impulses.
  • Then, these electrical impulses are sent to controllers or PLCs for processing and recording.
  • Strain gauges are used by pressure transducers to gauge the force applied to them.
  • In contrast to other pressure categories, vacuum pressure is measured via transducers.
  • With pressure, it becomes convex as opposed to concave (i.e. it bubbles out), allowing to monitor negative pressure.

Features

  • Dwyer Instruments DPG-200 vacuum transducer has a backlit, 4-digit display which offers clear parallax-free reading and decreases the potential for errors.
  • It is provided with a heavy-duty, aluminium case to meet NEMA 4X (IP66) requirements for use in rough or outdoor environments.
  • The unit is powered by 12 to 24 VDC/VAC and contains two alarm set points.
  • It has a four-button keypad to allow easy access to features. These features include backlight, peak & valley, auto zero and conversion of the pressure units.
  • This model features an anodized aluminium extruded enclosure with recessed grooves, black polycarbonate front & back cover, Buna-N O-rings, polycarbonate overlay and 316L stainless steel sensor construction for prolonged use.

Frequently Asked Questions

How many PSI is full vacuum?

14.7 psi.

How is the vacuum different from pressure?

It is only a pressure that is a magnitude lower than the atmospheric pressure in the area. A vacuum can be any pressure between 0 psi and 14.7 psi.

How do you increase the vacuum pressure?

  • There are two ways to change the pressure in a vacuum system.
  • First, by varying the pumping speed (changing the pump's speed or throttling by closing a valve).
  • Second, by allowing gas to enter the system (opening a valve).
