Transmitters - Applications

• Major OEM Sales Targets
• Irrigation
• Compressed Air Systems
• Hydraulics
• Compressor Refrigerant Pressure
• Machinery

12
626 Single Pressure TransmitterApplication -
Irrigation

• Example Golf Courses, Agriculture
• Modulate pump output to vary flow in order to
  meet changing demand
• Demand is determined by
• of active sprinklers
• Time since and amount of last rainfall
• Season

13
626 Single Pressure TransmitterApplication -
Irrigation

• Advantage over constant flow systems
• Save money by lowering output at times of
  decreased use
• Avoid waterlogging
• Ensure consistent watering for best results.

Demand for these systems has tripled in five
years!!
14
626 Single Pressure TransmitterApplication Air
Compressors

• Compressed air systems
• Dynamic in nature
• Add variable speed compressor to base load
  compressor to satisfy demand

15
626/628 Single Pressure TransmitterApplication
Air Compressors

• 626/628 Monitors downstream pressure, provides
  input to VFD to modulate to setpoint
• Save money
• Comp. Air

16
626/628 Single Pressure TransmitterApplication
Fire Pumps

• What are fire pumps?

Auxiliary pump systems designed to augment water
pressure during sprinkler system activation
What has changed?
New regulations require continuous recording of
line pressure calling for continuous, rather
then single point, pressure monitoring
17
626/628 Single Pressure TransmitterApplication
Fire Pumps
626/628 Provides Continuous pressure data to
chart recorder in addition to providing for
emergency system start-up in case of sprinkler
activation
CRITICAL USE TESTED APPROVED
