IF Series Inductive Pickup with Amplier Installation Guide
The IF series inductive pickup and VIEG
amplier are applied in high temperature
applications beyond the normal operating
range of standard magnetic pickups. The
inductive sensor generates a sinusoidal output
signal with an amplitude between 0.5mV to
0.5V. The VIEG is designed to amplify and
shape this signal providing a square wave
output voltage of 8V pp.
Application of the IF Series Inductive Pickups
The selection of an inductive pickup is recommended when the operating temperature exceeds
176°F/80° C. Operation can be expected up to 360°F/180°C with the standard version and up to
465°F/240°C using the HT version.
Because of the low signal levels involved, the following guidelines should be followed:
• Only use braided, shielded cable. The shield should only be connected at the amplier module as
indicated. The distance between the amplier and sensor should not exceed 3 meters/10 feet.
• Because of the low signal levels, direct the electronics as far as possible from other
electromagnetic eld sources.
• The pickup should be inserted until hand tight, then turned back 1/4rev. Tighten the lock nut to
secure this position.
• The meter can be mounted in any manner, however, every effort should be made to minimize
vibrations. Strong vibrations can have a microphonic effect on the pickup sensor. Flexible
connections will help to reduce pipeline vibrations considerably where this is a concern.
