PRESSURE

[20.64]

The Series 616D Din Rail Differential Pressure Transmitter senses the pressure of
air and compatible gases and sends a standard 4-20 mA or 0-10 VDC output signal.

The 616D enclosure is specically designed to mount on a 35 mm DIN rail in a panel.

This mounting style allows for several units to be mounted closely together reducing
required space. The span and zero controls are for use when checking calibration.
They are not intended for re-ranging. Versatile circuit design enables operation in
2-wire current loops.

FEATURES/BENEFITS

• Simple calibration push-buttons to set zero and span

• Cost effective and compact device suitable for OEM applications where space,
simplicity, and value are key

APPLICATIONS

• Air handlers

• Variable air volume
