Requirements

(1)

(1) Model 3500/3700 only. Sensor cabling not applicable to Model 3300/3350.

With Sensor Interface Option 5:

• Requires standard 4-wire twisted-pair shielded signal cable between the sensor and the

transmitter. Micro Motion recommends using Micro Motion 4-wire cable.

With Sensor Interface Option 6:

• Requires standard 4-wire twisted-pair shielded signal cable between the transmitter and the

remote core processor. Micro Motion recommends using Micro Motion 4-wire cable.

• Requires Micro Motion 9-wire signal cable between the remote core processor and the sensor.

Depending on the order, 10 feet (3 meters) of 4-wire cable or 10 feet (3 meters) of both 4-wire and

9-wire cable are shipped with the order. For longer cable lengths, contact Micro Motion.
