Table A-6. Maximum Recommended Viscosity and Coating / Build-Up
CE-mark
The 4–20 mA HART version (output option code H) complies with applicable directives (EMC
and ATEX).
Based on the low emitted effects from the gauges (well below 0.1 mW) compared to limits
given by the Rec. 1999/519/EC, no additional measures are needed.
Coaxial Twin lead Single lead
Maximum viscosity
500 cP 1500 cP 8000 cP
(1)(2)
(1) Consult your local Emerson Process Management representative in the case of agitation/turbulence and high viscous products.
(2) For viscous or sticky applications, it is not recommended to use centering discs mounted along the probe.
Coating/build-up
Coating not recommended Thin coating allowed, but no bridging Coating allowed
