New Transmitters Now Available with RS-485 Communication

Measurement transmitters

ROTRONIC’s BF2 series of measurement transmitters, BF220 process pressure transmitter, and the BF227 are available with RS-485 communication.

BF220 is ideal for measurement of absolute pressure in applications with fast temperature changes; compressed air; heating, ventilation, and air conditioning (HVAC); and pneumatic systems. It measures the pressure of neutral gases and nitrogen in piping and closed containers.

The pressure of the medium being measured acts on a pressure cell, which converts the pressure into an electronic signal.

The new process pressure transmitter is an ideal complement to the low dew point (LDP) probe HC2-LDP and ATmosphères EXplosibles (ATEX) version Hc2-LDP-EX.

Benefits of the new process pressure transmitter with RS-485 interface (BF227) are:

  • Compact and robust construction
  • Measurement range: 0bar to 10bar
  • Piezo resistive steel sensor
  • Zero and range adjustable with internal potentiometer
  • Digital RS-485 communication communication with independent networks
  • International protection (IP): IP63 / IP65
  • Accuracy at 20°C ±2 K: ±0,25% full scale (FS) max
  • Long-term stability: ±0,2% full scale / year
