TP303
Profibus PA Position Transmitter
The TP303 is from the first generation of Profibus-PA devices. It is a 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.
The TP303 is versatile and reliable, and has very high accuracy. It may be used for control valve stem position measurement or in any other position sensing application such as louvers, dampers, crushers, etc. Since the TP303 uses a non-contact magnetic coupling for position sensing, it is less sensitive to vibration than other solutions, resulting in longer operational life. The TP303 is part of Smar's complete 303 line of Profibus-PA devices.
