Rosemount Analytical 1066 2-wire liquid transmitter series

The Rosemount Analytical 1066 2-wire liquid transmitter series from Emerson Process Management is suitable for pharmaceutical and food and beverage applications and harsh environments like chemical plants, metals processing and effluent monitoring.

The series is registered under the Interoperability Test Kit 6 (ITK6) from Foundation fieldbus. ITK6 compliance means the transmitters have field diagnostics and common software downloads.

The transmitters 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 allows continuous pH correction for free chlorine measurement.

The company claims the transmitters’ smart pH sensor capability eliminates the need for field calibration. The smart capabilities also enable the transmitter to accept pre-calibrated Rosemount Analytical smart pH sensors.

The transmitters can use analog output function blocks to link to temperature and pressure measurements from the bus for temperature and pressure compensation, which may increase the accuracy and responsiveness of the measurement. They also have analog control and math function blocks for use by the 1066 or other devices on the bus to facilitate control in the field.

The HART version of the 1066 is switchable between HART 5 and 7, allowing the transmitters to be used with HART 7 capable, as well as legacy, hosts.

Housed in a 1/2 DIN enclosure, the transmitters have a large, user-friendly display. A diagnostic key allows for fast troubleshooting.

The transmitters’ configuration is compatible with the smart wireless Thum adapter for commissioning to Emerson wireless networks. The transmitters use low-frequency noise reduction, and include cable capacitance and series resistance.
