653 Two-Wire General Purpose

Two-Wire pH / ORP Transmitter

IC CONTROLS has incorporated microprocessor technology into the two-wire transmitters. pH and ORP measurement can be critical to your process and must be strictly monitored and maintained. Analyzer intelligence goes beyond measurement and control, providing the user with calibration data including sensor cell constant, range and diagnostics. Information can be communicated for trending or advanced control, even to remote locations. Ultimately, the user has superior control with a competitive advantage.

Description

The analyzer stores the last calibration record Settings can be viewed, functions tested, and calibration updated using the front panel keypad without opening the enclosure.

These analyzers / transmitters are 2-wire 24 VDC operated. Installation costs are less because no 115/240 VAC is needed at the transmitter field location. They require a separate 24 VDC supply and typically a 4-20 mA receiver.

The industrial two-wire pH/ORP transmitter from IC CONTROLS, the Model 653, gives you maximum flexibility, reliability, and ease of use. The transmitter is easily applied and panel mounts in a standard &fract12; DIN size RFI/EMI-resistant case, with options available for pipe or wall mount. When needed, a very rugged explosion proof case, option -9, is also available.

The model 653 is not just a transmitter, it is a full pH or ORP analyzer! You get full sensor functions, standardize (reference offset) and slope (measurement efficiency) adjustment, plus independent, program-adjustable 4-20 mA zero and span. Even with old deteriorated sensors, you enjoy higher accuracy over the full pH or ORP scale. This analyzer corrects for the low efficiency and large offsets typical of electrode age.

Easy Program Does What You Expect

  • Field configurable for pH or ORP measurement
  • Auto calibration, recognizes your buffers
  • Self- and sensor diagnostics
  • Output hold during calibration
  • Reversible, programmable 4-20 mA zero and span
  • Adjustments by keypad
  • Program remembers what you were doing
  • Instant keypad return to sample
  • Easy to operate without menu or manual
  • LCD displays pH or ORP, temperature, mA output and calibration status

Easy Maintenance

  • Reliable, separately powered and input-output isoldated circuit prevents computer interface problems
  • Calculates pH sensor slope and offset
  • Durable IP65 (Nema 4X) housing withstands hosing down. Survives acid and caustic fumes, humidity, etc.

Use Any Electrode

  • Submersible
  • Flow
  • Insertion / retractable

Use Either of the Following

  • Local digital indication
  • 4-20 mA signals

Note: The model 653 is 24 VDC two-wire loop-powered and requires a source of 24 VDC power somewhere in the loop.
