The Solu Comp Model Xmt family of transmitters can be used to measure pH, ORP, conductivity (using either contacting or toroidal sensors), resistivity, oxygen (ppm and ppb level), free chlorine, total chlorine, monochloramine and ozone in a variety of process liquids. The Xmt is compatible with most Rosemount Analytical sensors. See the Specification sections for details.

The transmitter has a rugged, weatherproof, corrosion resistant enclosure (NEMA 4X and IP65). The panel mount version fits standard ½ DIN panel cutouts, and its shallow depth is ideally suited for easy mounting in cabinet-type enclosures. A panel mount gasket is included to maintain the weather rating of the panel. Surface/pipe mount enclosure includes self-tapping screws for surface mounting.

The Model Xmt includes the HART® and Foundation Fieldbus digital communication protocols. Digital communications allows access to AMS (Asset Management Solutions). AMS can be used to set up and configure the transmitter, read process variables, and troubleshoot problems from a personal computer or host anywhere in the plant.

DIGITAL COMMUNICATIONS:
HART —
Power & Load Requirements: Supply voltage at the transmitter terminals should be at least 12 Vdc. Power supply voltage should cover the voltage drop on the cable plus the external load resistor required for HART communications (250 Ω minimum). Minimum power supply voltage is 12 Vdc. Maximum power supply voltage is 42.4 Vdc.
Analog Output: Two-wire, 4-20 mA output with superimposed HART®3 digital signal. Fully scalable over the operating range of the sensor.
Output accuracy: ±0.05 mA

FOUNDATION FIELDBUS —
Power & Load Requirements: A power supply voltage of 9-32 Vdc at 13 mA is required. Fieldbus Intrinsically Safe COncept/FISCOcompliant versions of Model Xmt Foundation Fieldbus transmitters are available.
