Types of Electrical Connectors Used for Hamilton Process Analytics Sensors

VP – This is a common connector used throughout the Hamilton sensor product line. VP is abbreviation for “VarioPin”. The VP designation often includes a number referring to the number of exposed poles on connector head. Example VP6 = 6 pole.





K8 connectors are typically used on pH / ORP sensors which lack temperature compensation. These connectors have a two pole design comprised of the center core and outer metallic threaded connection.




S7 & S8 – S7 and S8 connectors are typically found on sensors which no temperature compensation. They are the same basic design however S8 connectors have PG13.5 mounting threads, while S7 connectors do not. These connectors are recessed thus care must be taken to avoid moisture getting trapped which could lead to a short circuit.




M12 - Metallic threaded M12 connectors are found on Dissolved Oxygen Sensors and Cell Density products. M12 adapters have either 4 or 8 poles hidden within the socket. Since the poles are recessed avoid getting moisture inside the connection.





T82 – The T82 connector is sometimes known as a D4 connector. It uses a twist lock design to secure the cable to the sensor. These connectors are less common.





Memosens – These inductive electrical connectors are only found on digital pH sensors using Memosens technology. They use a twist lock design to affix the cable. There are no exposed metallic
connections on Memosens connectors.

A Visual Understanding of Steam Induced Water Hammer


When improperly drained of condensate in a high pressure steam main fills with condensate and completely surrounds the steam, an implosion takes place causing devastating water hammer.

Draining condensate and keeping it away from the steam by using proper steam trapping equipment will prevent this from happening.

The following video, courtesy of TLV, dramatically demonstrates the principle behind water hammer and its potentially devastating effects.

Understanding Cavitation in Valves

Download the Flowserve Cavitation document here.

According to Wikipedia, "Cavitation is the formation of vapor cavities in a liquid, small liquid-free zones ("bubbles" or "voids"), that are the consequence of forces acting upon the liquid. It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities in the liquid where the pressure is relatively low. When subjected to higher pressure, the voids implode and can generate an intense shock wave."

Cavitation presents serious concerns to engineers and specifiers of  control valves. Understanding ways to mitigate cavitation is important. Flowserve has put together this excellent document on understanding cavitation and offers solutions on reducing or eliminating its effects.
