A.3.6 Antenna versions
Cone antenna
Best choice for most applications, including closed

vessels, still pipe/chamber installations, and open air
applications
Extended cone antennas are available for tall nozzles

(option code S1 and S2). Depending on measurement
conditions, a reduction of sensitivity close to antenna end
might be present.
Process seal antenna
All PTFE wetted parts ideal for use in corrosive and

hygienic applications
Suitable for applications with heavy

condensation/build-up
1. Fully functional transmitter with sensor module, housing, terminal block, LCD
display, and covers.
2. The transmitter meets IP 68 at 9.8 ft. (3 m) for 30 minutes.
