616 D Differential Pressure Transmitter 02450

The Series 616D 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 specifically 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.

• 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
