The Series 616 Differential Pressure Transmitter senses the pressure
of air and compatible gases and sends a standard 4-20 mA output
signal. A wide range of models are available factory calibrated to specific
ranges as listed in the chart below. The span and zero controls are for
use when checking calibration. They are not intended for re-ranging to a
significantly different span. Versatile circuit design enables operation in
2, 3 or 4-wire current loops.
For applications requiring direct pressure readings or percent of full span
output, the optional Model A-701 Digital Readout makes an ideal
companion device. It provides a bright red 0.6˝ high, 3-1/2 digit LED
display while supplying power to the Series 616 transmitter. For
additional information on these and other transmitters, see the Dwyer
Instruments, Inc. Full Line catalog.
