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

What is a pre-pressurized sensor and why would I choose it?

The electrolyte within the sensor is pressurized at the factory. This feature helps prevent against clogging and poisoning of the sensor due to the process liquid. The design is hygienic and well suited for fermentation applications found in biopharma, food, and beverage markets.

FAQ

What is the Everef F Reference System?

The Everef-F reference system uses a silver ion barrier to separate the reference element from the electrolyte. This design prevent Ag+ precipitation from occurring and clogging the diaphragm. It is a perfect design for applications with proteins or sulfides in the process liquid.
