Selection Tips

  1. Choose 3051CD for low differential pressure applications like filter monitoring or flow across orifice plates.
  2. Use 3051CG when measuring gauge pressure in tanks or pipelines.
  3. Opt for 3051CA for absolute pressure in vacuum or sealed systems.
  4. Select 3051S when ultra-high accuracy, diagnostics, or scalability are critical.
