Overview

The POWERFLEX 2200 is a 2-wire 4…20 mA guided radar level transmitter based on the Time Domain Reflectometry (TDR) technology. The device is designed to operate in safety-related and non-safety-related liquid applications of the nuclear power industry. It has been qualified according to IEEE 323, IEEE 344 and RCC-E and conforms to nuclear standards such as ASME Section III or RCC-M.

Product features and options depend on device configuration: Contact us to make sure that your preferred functionality can be combined in one device.

  • Referenced for nuclear applications
  • Four versions to suit safety- and non-safety-related applications
  • Conforms to nuclear standards (e.g. ASME Section III, RCC-M)
  • Qualified according to IEEE Std 323, IEEE Std 344 and RCC-E
  • For high radiation levels, the converter can be installed up to 450 m / 1476.38 ft away from the probe
