PICK-UP
DATA SHEET
FNL
The Pick-up is a device utilizing an induction potentio-
meter and designed for converting an angle of rotation into
electrical signals. The input axis is mechanically turned at a
certain angle and this rotation is then converted into electri-
cal signals of 4 to 20mA DC. It is ideally suited for use as
a displacement type transmitter.
FEATURES
1. High reliability
Use of a contactless induction potentiometer assures a
long life and high reliability.
2. Various specifications available
The Pick-up can be equipped with flameproofing, intrin-
sically safe explosionproofing, a large indicator, an ar-
rester and other devices.
3. Easy maintenance and handling
The Pick-up is compact and lightweight, and zero and
span adjustments plus output signal checks can all be
easily made on the front panel.
