The Model 5081 Two-Wire Transmitter from Emerson Electric is designed for measuring pH, ORP, conductivity (both contacting and toroidal), dissolved oxygen, free and total chlorine, and ozone in various process liquids. It supports two communication protocols: HART and FOUNDATION Fieldbus, allowing for integration into existing systems and remote monitoring capabilities.
The transmitter features a large two-line display that shows the primary measurement and temperature, with easy readability. Its robust Type 4X enclosure ensures protection against harsh environments, while the intrinsically safe design permits use in hazardous locations when paired with appropriate safety barriers. The device includes non-volatile memory to retain settings and calibration data during power outages.
Additional functionalities include automatic temperature compensation for pH measurements, continuous diagnostics for sensor performance, and a simple menu structure for user-friendly operation. The Model 5081 is compatible with most Rosemount Analytical sensors, making it a versatile choice for various applications in process control and monitoring.
The Model 5081 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, and ozone in a variety of process liquids. Choice of communication protocol: HART® or FOUNDATION® fieldbus. The transmitter features a simple menu structure and is housed in a Nema 4x enclosure. It is an intrinsically safe design, allowing it to be used in hazardous areas.
