Emerson's Rosemount Analytical 1066 Series two-wire liquid transmitters are claimed to offer the broadest coverage of process parameters yet.
They can measure pH, ORP, resistivity/conductivity, per-cent concentration, total dissolved solids, total chlorine, free chlorine, monochloramine, dissolved oxygen and dissolved ozone. A second sensor input also allows continuous pH correction for free chlorine measurement.
What's more, they feature the latest version of HART 7, for plant communication, and are the first pH transmitters to be registered under the Interoperability Test Kit 6 (ITK6) from Foundation fieldbus.
"[They] include many capabilities that we have implemented into our high-end instruments, such as Smart pH sensor capability, which eliminates the need for field calibration," comments Dave Anderson, marketing director at Emerson Process Management.
Interestingly, the 1066 can also use analogue output function blocks to link to temperature and pressure measurements from fieldbus for compensation purposes, to improve measurement accuracy and responsiveness.
And it's compatible with Emerson's Smart Wireless THUM adapter for commissioning to Emerson wireless networks.
All that power is housed in a 1/2 DIN enclosure, with a large display and built-in diagnostics.
