The primary considerations when selecting a process adaption are related to the process media, installation point and your cleaning and calibration requirements. Based on your specific process requirements, you will want to consider if you need a stationary or retractable design, what process connection compatibility you require, insertion length, wetted materials, and whether a sensor protective cage is needed to protect the sensor tip from damage in high particle load samples.
