Longtime leader in the measurement of pH, conductivity, and dissolved oxygen, the TBI Company was acquired by Bailey Controls in 1985. TBI-Bailey-based products include sensors, transmitters, and controllers for the total management of liquid analysis variables. Among the company's strengths are its line of durable sensors, which withstand harsh process environments far longer than many competitive models.
TBI-Bailey also provides a range of both conventional and "smart" transmitters for interface to host control systems, as well as stand-alone controllers which form the basis for "packaged" liquid analysis solutions. Based in Carson City, Nevada, TBI-Bailey joined the ABB catalog in 1999 with the ABB acquisition of Elsag Bailey. The legacy of innovation and product quality can now be found embedded in many ABB products.
