oise

For minimum noise susceptibility, avoid

running the transducer’s cable in a con-

d

uit that contains high current AC power

cables. Where possible avoid running

the cable near inductive equipment.

Shielded Cable

Units with shielded cable electrical termi-

nation, connect the drain wire to the

guard terminal on the read out device or

measuring instrument, if available. In all

other cases connect to the ground or to

the power supply negative terminal.

Vent Tube (Cable Termination Only)

The cable has a clear Teflon

®

vent tube

required at pressure ranges below 500

psi to provide atmospheric reference.

The open end should be placed in a

dry area.
