Series 616KD-LR Differential Pressure Transmitter - Low Ranges

High Accuracy, Ranges Down to 0.1 in w.c. (25 Pa)

The Series 616KD-LR Differential Pressure Transmitter is designed for simplicity, making it the ideal choice for installers and maintenance professionals. These low range instruments not only alleviate cumbersome turn pots typically found in most transmitters, but eliminate entirely the need to span the instruments during calibration. With single digital push button, both ZERO AND SPAN are calibrated properly, nothing else is required. No additional reference pressure sources or separate calibration devices are necessary.

Product Applications

  • Air handlers
  • Variable air volume
  • Duct pressure
  • Filter monitoring
  • Wide selection of low ranges and accuracy cover numerous applications minimizing components and standardizing on design
  • Simple calibration push-buttons to set zero and span, saving time installing and maintaining over the service life
  • Cost effective and compact device suitable for OEM applications where space, simplicity, and value are key
  • Simultaneous current and voltage outputs
  • Optional 1/4" NPT process connection allows for use with metal barbed fittings or compression fittings for use with metal tubing
  • Plenum rated units meeting UL Standard 2043
