Emerson F-SERIES SENSOR Manuel D’Utilisation

11

If the transmitter is mounted remotely from the sensor, the maximum distance between the sensor and 
transmitter depends on cable type. See Table 2.

For high-temperature and extreme high-temperature F-Series sensors, note the following:

• For sensors with a Model 1700/2700 transmitter, the transmitter is considered to be integrally mounted 

on the sensor, so Table 2 does not apply.

• For sensors with a junction box or core processor, the limits in Table 2 apply only to the wiring 

between the junction box or core processor and a remotely mounted transmitter. The length of the 
flexible conduit on which the junction box or core processor is mounted does not need to be 
considered.

Micro Motion sensors do not require a straight run of pipe upstream or downstream.

After the sensor and transmitter have been installed, you must perform the zeroing procedure. During the 
zeroing procedure, flow through the sensor must be halted and the sensor tubes must be completely full of 
process fluid. A shutoff valve, downstream from the sensor, is recommended to halt flow during the zeroing 
procedure. For more information about zeroing, refer to the instruction manual shipped with the transmitter.
