Reference conditions are 70 °F (21 °C), and routing data for three additional network
devices.
A.1.2
Environment
Vibration resistance
No effect when tested per the requirements of IEC60770-1 (1999): High Vibration Level -
field or pipeline (10-60 Hz 0.21 mm displacement peak amplitude / 60-2000 Hz 3g).
Electromagnetic compatibility
•
Meets EN 61326-1:2013, EN 61326-2-3:2013, and NE21:2012 if installed in metallic
vessels or still pipes.
•
For optimal single lead probe performance in non-metallic tanks, the probe must be
mounted with a metal flange, or screwed in to a metal sheet (d > 14 in./350 mm) if a
threaded version is used.

A.1.3
Contamination/product build-up
•
Single lead probes are preferred when there is a risk of contamination (because build-
up can result in the product bridging across the two leads for twin versions; between
the inner lead and outer pipe for the coaxial probe).
•
For viscous or sticky applications, PTFE probes are recommended. Periodic cleaning
may also be required.
•
For viscous or sticky applications, it is not recommended to use centering discs
mounted along the single lead probe.
•
Signal Quality Metrics (option code DA1) can be used to determine when to clean the
probe. Transmitters equipped with the Diagnostics Suite option can calculate Signal
Quality Metrics.
