Ateq ERD620

After 40 years of experience and 100 000 leak detectors and flow testers installed worldwide, ATEQ presents its revolutionary compact flow and pressure event tester.

ATEQ ERD620 is a new Series 6 generation of pneumatic testers with:

  • new design differential pressure transducers
  • new electronic and pneumatic modules
  • new user-friendly interface
  • new accessories and functions

ATEQ ERD620 is used to test components that are expected to react to a specific pressure. The instrument generates an increasing or decreasing pressure ramp until the expected event occurs, such as:

  • relay contacts opening or closing
  • safety valve opening or closing
  • nominal flow achieved at certain pressure

The tester checks whether the expected event occurred within the specified pressure range, while measuring the air flow.

 

  • Graphic user-friendly interface with high-contrast color screen
  • Automatic test pressure adjustment
  • Programmable pressure ramp increase and decrease
  • Direct or indirect flow measurement
  • Various flow measurement ranges: from 1 l/h to 10.000 l/h
  • Flow measurement in:
    • SI standard units
    • US units
    • custom calibrated units
  • The entire measuring system integrated in one module
  • Possibility of programming 128 test programs
  • Communication:
    • RS232: printer, barcode reader, PC computer
    • USB «master»: transfer to external USB memory (parameters, results, statistics, …)
    • USB «slave»: supervision
    • Ethernet/IP or USB «master» on the front panel or SD reader for saving results.
    • Available communication protocols: ModBus, ProfiBus, DeviceNet, ProfiNet, EtherNet/IP, EtherCAT.
  • 9 inputs / 7 outputs board – enables selection of 128 programs, test cycle START/STOP, OK/NOK result signals, etc.
  • Date and time indication, language and unit selection, ability to adapt tests to your requirements, automatic measurement cycle, …
  • 2 pneumatic outputs for automation control
  • Programmable 6 x 24 V outputs for external devices
  • 2 analogue outputs 0-10V or 4-20mA
  • Connections to the test item
  • Automatic calibration check mode
  • Tight shut-off and switching valves for construction of complex test circuits

Flow and pressure event testing of safety valves and pressure safety systems, non-return valves, sensors, pressure transducers and switches, …
