Retort pressure logger = Philog

Autonomous temperature and pressure data recorder for the food industry

Description of the retort pressure logger

This PHIlog temperature and pressure data logger is insulated with a Peek (high-temperature polymer) envelope that protects it from temperature shocks. This heat shield preserves the electronics and battery over the long term.
In addition, this material is much lighter than stainless steel and greatly reduces measurement errors caused by the sensor’s presence in the observed environment. With a high response time, this recorder is extremely accurate.
Data is collected via an inductive interface, which eliminates any problems with connector fouling and therefore communication.
