Down the street from Phase Sensors’ facility in Edmonton, Canada is the coldest place in the world. Dr. John Davis operates a dilution refrigerator utilizing a demagnetization stage to probe fundamental physics at the lowest obtainable temperatures. Dilution refrigerators are used to provide sub-Kelvin temperatures (less than -272.15°C) for fundamental physics and materials experiments. A Dilution refrigerator utilizes a multiphase mixture of 3He and 4He where evaporation of 3He from the liquid phase to the gas phase cools the chamber.

The benefits of quartz resonant sensors can be applied to fluid properties characterization. Quartz tuning forks are incredibly sensitive and stable sensors that can be used to discover the fluid properties that surround the resonant element. By vibrating a tuning fork in a liquid, you can make a precision measurement of the fluid viscosity and density. Our LUVD1 QuartzMEMS density and viscosity sensor integrates a high precision Lock-In Amplifier with a quartz tuning fork element. We package the quartz tuning fork in a 15,000psi capable high-pressure feed through with an integrated high precision temperature measurement.
