More than just sensor protection.

Hamilton’s broad sensor housing portfolio has a solution to reliably integrate Hamilton’s process sensors in any industrial process. These sensor housings also facilitate seamless integration in the process stream and offer easy maintenance and long-term durability.

With options like static housings for batch process or retractable housings for continuous operation, our robust housings support excellent sensor performance in areas ranging from delicate biopharmaceuticals to aggressive wastewater and virtually everything in between.

  • We particularly appreciated the professional and personable approach.

    The training on pH sensors was highly beneficial for us. After a detailed introduction to the fundamentals of pH measurement, electrode measurement principles, and the topic of troubleshooting/prevention, we had sufficient time to ask our specific questions. This enabled us to apply what we learned immediately and integrate it directly into our laboratory routine. We particularly appreciated the professional and personable approach of Mrs. Näf-Rüdiger, who guided us through the informative and application-oriented training session.

FAQ

How much torque is needed to install a sensor with PG13.5 threads?

Sensors with PG13.5 threads rely on the o-ring to seal against process pressure. Finger-tight (approximately 2 Newton Meter or 18 inch-lb) should be sufficient to install the sensor without leakage. Additional tightening beyond this can deform the o-ring or strip the threads.

FAQ

How to select a FlexiFit sensor housing?

FlexiFit static sensor housings should be chosen based on the process connection on your vessel and the sensor compatibility. Process connection options include G1-1/4" (25mm Ingold), Triclamp, and Varivent. FlexiFit housings compatible with pH / ORP sensors have protection prongs to decrease risk of breakage. FlexiFit housings compatible with DO, conductivity, and cell density sensors are flush to avoid any interference with the measurement.

FAQ

How are the housings for refillable pressurized pH / ORP sensors such as the ChemoTrode actually pressurized?

The ChemoTrode requires a pressurized housing such as the MasterFit or RetractoMaster for proper installation. These housings use a Dunlap valve (bicycle tube valve) which permits pressurizing the chamber with the sensor up to 6 Bar. A simple bicycle pump with a Presta or Dunlap pump head can be used for this purpose.
