Product Overview

Introduction

The Thermo Scientific LevelPRO is designed to provide reliable and
accurate level measurements. With

F

OUNDATION

™ fieldbus

, the gauge

also provides users with access to control or program parameters via a host
system.

The gauge consists of a source head containing the radioisotope source and
the detector-transmitter. The radioisotope source emits gamma radiation
that passes through the process material. The detector measures the energy
of the radiation arriving at the detector after passing through the process
material (and vessel walls). The gauge determines the level of the process
material by measuring the amount of radiation arriving at the detector,
which varies with the level of the process material.

Note

This guide contains information specific to applications using the

LevelPRO with

F

OUNDATION

fieldbus

. For information on the standard

LevelPRO, reference the LevelPRO user guide (P/N 717778).

Fieldbus

Overview

Fieldbus is an all-digital communication system between devices on the
bus. The LevelPRO with

F

OUNDATION

fieldbus

provides the following:

●

Execution of control functions (algorithms) in the actual device

●

Device registration with the

Fieldbus Foundation™

, ensuring

compatibility with the devices of other systems

●

Ability to configure using device specific device description (DD)

●

Ability to send data directly between devices

Note

This manual assumes a working knowledge of

F

OUNDATION

fieldbus

terminology and practices. For additional information on
