Smart differential pressure transmitter

  • Model: FPTG
  • Type: Pressure differece gauge
  • Accuracy ratio: 0.2%FS
  • Type: Digital
  • Product description: Smart differential pressure transmitter

Foster FPTG is pressure transmitter that suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure. Outputs a 4~20mADC signal corresponding to the measured differential pressure. Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via HART communications. Other key features include quick response, remote set-up using communications, self-diagnostics and optional status output for pressure high/low alarm.
