N.REL_PR_3225-CONVERTER-0-e1645448975499.png

We are proud to present to you the latest addition to the PR 3000 range of compact 6 mm devices. The PR 3225 adds a universal frequency converter to the trusted and renowned PR 3000 product series, which has played a vital role in our customers’ process solutions for more than a decade.

PR 3225 supports a broad range of industry standard input types, custom-programmable sensor voltages and output options:

  • Programmable f/I/U converter
  • Input: NAMUR, NPN, PNP, Tacho, TTL & S0
  • Two output options – 3225A: mA / V, 3225B: Alarm relay
  • 0.001 Hz – 100 kHz input/output span
  • Accuracy < 0.06% / span
  • Response time < 30 ms
  • NAMUR NE21, NE43
  • 2.5 kVAC, 3-port galvanic isolation

For easy deployment, the typical configuration can be achieved via DIP-switch programming. With the optional PR 4590 ConfigMate and communication interfaces in the PR 4500 series, it is easy to monitor and program the measurement point and take advantage of the advanced features supported by PR 3225.

Based on the strong foundation of the PR 3000 series with the well-known and unique features such as high accuracy, fast response time and low temperature drift, the PR 3225 is a flexible and

and easy-to-use product when measuring frequency signals.

With the outstanding EMC specifications, that meet or exceed industry standards, and 5-year warranty, you can look forward to many years of trouble-free operation with PR 3225.

What are frequency to current converters and what are they used for?

 

The process industry requires measurement and control of many process variables. Speed and flow rate are two such variables, where safety and product delivery demand accurate process control.

Sensors used to measure speed often take the form of proximity sensors, which detect a target as it passes by the sensor resulting in a pulse or frequency output proportional to the speed.

To enable these signals to interface with downstream equipment, the pulses or frequencies are often converted to a current or voltage signal. Frequency to current converters such as the PR 4225 and PR 3225 are used for this purpose.
