INTRODUCTION
The TP301 is from the well-know Hart
®
family of Smar’s devices. It is a smart transmitter for
position measurements. It can measure displacement or movement of rotary or linear type. The
digital technology and communication provide an easy interface between the field and control room
and several interesting features that considerably reduce the installation, operation, and
maintenance costs.
TP301 uses a magnetic coupler without physical contact to measure the position. Therefore, it is
immune to vibrations resulting in a larger operational timelife. The magnetic coupler replacing the
mechanical connection, results in a clear reduction of the deadband. TP301 can be set up in any
linear or rotary valve, actuator or a variety of other equipment, such as floodgate skylight, dampers,
rolls mill height, crusher, etc.
The TP301, besides the normal function of position measurement and 4-20 mA output generation,
offers the following features:
Linear or rotary travel type;
0.1% F.S.;
Position calibration (4 - 20 mA) via local adjustment or remote calibration via configurator;
Non contact position sensing;
Optional LCD indicator;
Diagnostics and configuration via Hart
®
communication.
