GDH 200-14 Digital Absolute Pressure Gauge for Vacuum Resin Infusion

The lightweight and handy design qualifies this gauge to be an ideal daily companion for technicians and on the road. If the purpose of the vacuum infusion process is the production of high-quality parts, the use of a precise digital absolute pressure gauge is a must. The GDH 200-14 measures the pressure difference relative to the absolute zero of pressure and is unaffected by changing environmental conditions such as weather or altitude. Unlike analog dial gauges, usually mounted on the vacuum pump or resin catch pot, you know exactly what is happening inside the vacuum bag.

Description

The

Digital Vacuum Absolute Pressure Gauge GDH 200-14

Consistently producing high quality vacuum infusion parts is easy with the proper equipment. The “Made in Germany” GDH 200-14 is a digital vacuum absolute pressure gauge. It works like a Barometer and measures the pressure relative to absolute zero. Unlike analog dial gauges – which are usually mounted on the vacuum pump or catch pot – the GDH 200-14 allows to precisely gauge the process quality with digital precision and accuracy.

Benefits of GDH 200-14:

  • Lightweight and handy design – The GDH 200-14 weighs only 150 gr./5.3 oz.
  • Works properly with digital precision regardless of the environmental conditions
  • High performance reading supports a reliable process setup for high-quality output
  • Indicates without delay and with a resolution of 1 mbar(0.02953 inHG) if a leak has been found thus it saves time with the setup of a perfect vacuum infusion process
  • Performance Indicator – The only way to measure the pressure value in which a high quality infusion process takes place
  • Enables a performance check of the vacuum pump

How it Works

The digital vacuum absolute pressure gauge GDH 200-14 works the opposite to a conventional dial type vacuum gauge. Dial type gauges (the gauge usually mounted on the resin catch pot or vacuum pump) measure the pressure variations below the atmospheric pressure surrounding the gauge. This type of measurement can vary greatly depending on the weather conditions or altitude of your production facility. Absolute pressure gauges measure the pressure differential above absolute zero (or perfect vacuum). Using absolute zero pressure as a reference point provides a reliable and accurate measurement of vacuum levels. It is a fixed point of reference and not influenced by environmental factors.

Why accuracy is important

To produce high quality vacuum infusion or prepreg parts a vacuum range of 10mbar – 20mbar is required within the bagged system. Traditional dial type gauges can experience variations in a range between 1 and 3% of full scale. This is caused through the inaccuracy of the mechanism within the gauge and environmental variables! It is apparent that an analog vacuum gauge with a total accuracy of ±55 mbar is not an appropriate instrument for measuring an in-bag vacuum of 10 to 20 mbar. In order to reliably confirm that the system has been evacuated to this degree of vacuum the gauge needs to be accurate in this region.

Our mission is to provide the best products for high quality vacuum resin infusion applications. And the GDH 200-14 has proven its quality to composite experts and Todays leading composites manufacturers. The ability to detect changes in pressure precisely and instantly does save time and money during the process setup. It is also an excellent performance indicator for the quality of the vacuum infusion process and the produced products.

  1. Steve J.

    perfect tool to check vacuum integrity

  2. Jim Benzel

    Only way to go. Let’s you know if you have a microscopic leak, whereas a regular dial gauge may not. Good bag with no leaks = good part. Bad bag with a microscopic leak = bad quality part, appearance and structural. Some may think it’s kinda pricey, but I make medium to large carbon parts, the cost of losing one part is much more than the cost of this unit. I have 2. I don’t infuse until this gauge shows I have perfect bag.
