GENERIC MANUFACTURER SENSORS

Generic Manufacturer Sensor to Rosemount 8732 Transmitter

Identify the Terminals

Wiring Connections

First check the sensor manufacturer’s manual to identify the appropriate terminals. Otherwise, perform the following procedure.

Identify coil and electrode terminals

1.Select a terminal and touch an ohmmeter probe to it.

2.Touch the second probe to each of the other terminals and record the results for each terminal.

3.Repeat the process and record the results for every terminal.

Coil terminals will have a resistance of approximately 3-300 ohms. Electrode terminals will have an open circuit.

Identify a chassis ground

1.Touch one probe of an ohmmeter to the sensor chassis.

2.Touch the other probe to the each sensor terminal and the record the results for each terminal.

The chassis ground will have a resistance value of one ohm or less.

Connect the electrode terminals to Rosemount 8732 terminals

18 and 19. The electrode shield should be connected to terminal 17. Connect the coil terminals to Rosemount 8732 terminals 1, 2, and .

If the Rosemount 8732 Transmitter indicates a reverse flow condition, switch the coil wires connected to terminals 1 and 2.

This is a pulsed DC magnetic flowmeter.

Do not connect AC power to the sensor or to terminals 1 and 2 of the transmitter, or replacement of the electronics board will be necessary.
