Pulsarbar 720

High stability pressure/level transducer

Pulsarbar 720 product image

The Pulsarbar 720 is a pressure and level transmitter that is perfect for demanding applications throughout industry and the utilities. It is exceptionally stable and combines advanced sensing technology with modern manufacturing methods to provide a superb pressure transducer with very long life. The robust measurement cell provides good overrange protection and, with accuracy of at least 0.25% full scale, you can specify Pulsarbar 720 with confidence.

General purpose transducer

The Pulsarbar 720 features a stable and accurate proven CVD (Chemical Vapour Deposition) sensing technology that provides accuracy of 0.25% together with a welded stainless steel back end for all demanding or submersible applications. Models are available for pressure ranges of vacuum to 400bar and offer long-term stability. Gauge, absolute and relative pressure versions are available, with a choice of millivolt, voltage and current outputs.

Features:

  • High stability
  • ATEX EEx ia options available
  • Choice of pressure connections
  • Submersible and general purpose versions
