The SPAN™ 3.5" Liquid Filled Industrial Gauge is designed for rugged service applications, providing reliable and accurate pressure readings in high shock and vibration environments. This gauge is ideal for industries requiring precise pressure monitoring, such as mobile hydraulic equipment, fire apparatus, water purification/irrigation systems, bulk transport trailers, waste water/slurry management, and military and marine applications.


Features

  • Liquid Fill Fluid: Dampens gauge pointer movement for improved readings and longer life.
  • Zytel Case and Ring: Offers excellent resistance to chemical, weather, and corrosion attack.
  • Fully Filled Design: Internal breathing diaphragm eliminates the need for an air bubble, ensuring accurate readings.
  • Temperature Compensated: ICD compensates for changes in internal case pressure due to ambient temperature fluctuations.
  • Optional Rear Stud “QC” with Bottom Connection: Provides flexibility in mounting configurations.
  • NIST Calibration Certificate: Ensures accuracy and reliability.


Usage

The SPAN™ gauge is used to monitor pressure in various industrial applications. It is mounted using the back studs for wall mounting or the optional rear stud “QC” with bottom connection. The liquid fill fluid ensures stable readings even in environments with high shock and vibration.


Users

This gauge is utilized by professionals in industries such as:

  • Mobile Hydraulic Equipment
  • Fire Apparatus
  • Water Purification/Irrigation
  • Bulk Transport Trailers
  • Waste Water/Slurry Management
