TB26 Insertion / Submersion / Hot-Tap Stainless Steel Electrode
Brand: ABB GroupThe TB26 conductivity cell is easily installed into process lines and vessels via the integral 3/4"NPT threads, submersed directly into lines and vessels via the 1/2"NPT backthreads, or inserted into a process line or vessel through a ball valve.
A ball valve provides isolation between the sensor and the process, enabling sensor insertion and removal while the line or vessel is full.
This is accomplished by using a 1-1/2" standard ball valve.
A compression fitting with flushing ports enables the operator to wash away any leftover process fluid after removing the sensor.
The flushing ports also provide a quick and easy place to take a grab sample for calibration.
Variable sensor lengths are available for all Model TB26 sensor styles.
The hot-tap sensor can be used with the compression fitting and without the ball valve to provide even greater installation flexibility.
