stem

description

The analyzed system is the Level Transmitter LB490 Uni-Probe.

This transmitter is designed to perform measurements for fluids or bulk material level. The

measurement is based on the physical law of the attenuation of

Gamma

radiation

passes

through

medium. The Level Transmitter LB490 Uni-Probe combines long years of experience by

Berthold Technologies with the Gamma measurement technology.

The

Level

Transmitter

LB490

Uni-Probe is considered to be a Type B sub-system with a

hardware fault tolerance of HFT=0.

See Figure 1 for a system overview.

Figure 1: Sy

stem Ov

erv

iew

The

pulse

reading is converted via the evaluation unit into a 4..20mA signal. The HART™

communication is not considered safety-related and not subject of this report.
