Differential Precision Pressure Transmitter Dwyer 607 Series 607-3 607-4

Power Requirements	12 to 36 VDC
Electrical Connections	Screw terminals
Temperature Limits	-20 to 160°F (-29 to 71°C), 10 to 95% RH

Installation 1. Location: Select a clean, dry location free of excess vibration where the temperature of the unit with be between -20 and 160°F. Distance from the receiver is limited only by total loop resistance. See “ Electrical Connections”. The tubing supplying pressure to the transmitter can be run practically any distance. Long tubing lengths will not affect accuracy but response time will be increased slightly. 2. Position: The Series 607 Transmitter is not position sensitive. However, it is recommended that you avoid mounting with pressure connections pointing up because of the chance of condensed moisture entering the interior. Moisture can also be avoided by routing tubing with a low point just ahead of the transmitter. 3. Mounting: Attach to mounting surface with two #8 or #10 screws in the mounting slots provided. 4. Pressure connections: The Series 607 Transmitter is shipped with a short length of tubing installed between the ports to keep the interior clean. Remove it and discard after unit is mounted. Connect positive (above atmospheric) pressure to port marked “HIGH and vent the “LOW” port. Connect negative (vacuum) pressure to port marked “LOW” and vent the “HIGH” port. For differential pressures, connect the higher one to the “HIGH” port and the lower one to the “LOW” port.
