Leak and Flow Test Instrument: Test Types

Depending on your test needs, the Sentinel 3520 can be configured to meet your requirements for pressure range, flow meter range and flow configuration. The Sentinel 3520 supports the following test types:
  • Pressure/Vacuum Decay: Leak Standard
  • Pressure/Vacuum Decay: ΔP
  • Pressure/Vacuum Decay: ΔP/ΔT
  • Occlusion: Pressure or Vacuum
  • Ramp to Proof: Pressure (Burst Test)
  • Pressure Verify
  • Customizable Pressure / Flow Sequencing
  • Mass Flow (Flow Models)
  • Test Volume Verification (Flow Models)

Highlights

  • Pressure measurement and control resolution down to ±0.000,01 psi
  • Flow measurement down to ±0.2 % of full scale
  • High flow fast fill up to 300 SLPM
  • Test parts from 1 cc to 1,000,000 cc in volume
  • Helium evacuate and fill
  • Customizable pressure and flow sequencing
  • sigPOD controller equipped with PSV software, using digital process signatures for advanced test analysis
  • Use the sigPOD controller to conduct an additional in-process test such as press-fit, weld or dispense monitoring

Advanced Product Features

  • Patented PID controlled electronic regulators for pressure and flow
  • Fully adjustable control loop settings for electronic regulators
  • Valve-operated calibration port for automatic verification
  • Unit under test (UUT) isolate valve allows complete self-test without any external connection changes
  • Dedicated temperature sensors for advanced temperature compensation capability
  • Pass/fail decisions with digital process signatures (waveforms)
  • Air piloted valves to reduce effects of heat in high flow manifold version
  • Latching valves reduce effects of heat in low volume manifold version

Specifications

  • Test pressure accuracy: ±0.25 of full scale, best-fit straight line
  • Test pressure resolution: Down to ±0.000,01 psi
  • Flow accuracy:
  • ±1 % of reading when value is >20 % of full scale
  • ±0.2 % of full scale when value is <20 % of full scale
  • Pressure ranges (psig): 12 psig vacuum to 95 psig
  • Flow ranges: 0 to 30 SLPM
  • Volume ranges: 1 cc to 1,000,000 cc
  • Fill rate: 20 SLPM (low volume manifold) to 300 SLPM (high volume manifold)
