Diagnostics
General
Transmitter diagnostics with alerts include hardware and software errors, electronics
temperature, probe missing, and invalid measurement and configuration error diagnostics. In
addition to this, echo curve and variable logging including signal strength facilitate easy on-line
troubleshooting.
Diagnostics Suite
(option code D01 or DA1)
Signal Quality Metrics - Diagnostics package that monitors the relations between surface, noise
and threshold. The function can be used to detect abnormal conditions in the process such as
probe coating or sudden loss of signal strength. Signal Quality Metrics parameters are available
as Output Variables in Rosemount Radar Master, and can be sent to Distributed Control System
(DCS) to trigger an alarm.
Verification Reflector
(option code HL1, HL2, or HL3)
The reflector, which is available with single
lead flexible probes, is used to test and
continuously verify that the transmitter is
functioning properly in both tank and
chamber/pipe installations. Compared to
traditional diagnostics that only monitor the
transmitter electronics, the reflector can also
be used to diagnose the upper parts of the
probe inside the tank for e.g. build-up,
corrosion monitoring and other process
related conditions.
The primary use-cases for the reflector are:
Verification of transmitter and probe
(i.e. proof-testing)
High level supervision
(i.e. continuous monitoring of high level
condition)
Verification
During commissioning, the location and amplitude characteristics of the reflector are stored in
the transmitter. When the test procedure is later initiated, the stored reflector data is compared
to the current measurement to verify the integrity of the measurement electronics and upper
part of the probe.
During the test, the transmitter will output a level corresponding to the reflector position,
which can be used to verify the integrity of the transmitter output.
High level supervision
Additionally, the reflector’s unique echo characteristics aid the transmitter to locate a liquid
surface above the reflector, thereby offering increased reliability to detect high level conditions
at a user selectable limit.
The transmitter continuously monitors the status of the reflector and abnormal conditions
generate alarms and alerts as appropriate.
