The TB27 conductivity cell can be inserted or removed from process lines or vessels via a ball valve without disturbing the process. The TB27 sensor is designed for applications that exceed standard hot-tap sensor pressure ratings and for operator safety. An extraction housing isolates the operator from the process fluid. This housing has 1/4 in. ports for flushing, draining, pressurizing, or de-pressurizing this chamber. Ruggedly constructed of 316 stainless steel, these sensors withstand the most demanding processes and measurement requirements.
