300DGC Differential Pressure Gauge – Small Convoluted Diaphragm | Valley Instrument Service

300DGC Differential Pressure Gauge – Small Convoluted Diaphragm

Our new line of high-precision, high-pressure differential pressure gauges is available into the 2% accuracy range. Through innovative design and manufacturing methods, these new products firmly establish our price and quality leadership in this specialty industry.

Description

A close-coupled magnetic rack and pinion design uses high-quality magnets to achieve superior accuracy and the most linear scales in the industry. Our gauges are calibrated in the ascending pressure mode for the most common applications, such as filtration monitoring.  For special requirements, such as leak detection, we can calibrate the gauges in descending mode.

  • Ranges from 0.9 to 60 PSID
  • Can have a zero center dial
  • No flow through gauge
  • Electrical switch options
  • Best selling for liquid level
  • Best selling for cryogenics
  • Best selling for flow rate

 

Every precision gauge we sell is individually tested and serialized. Certification of calibration is available.
