A temperature gauge is configured to measure temperature in the pressure cell. A top is configured to provide a pressure resistant lid on the pressure cell. A coaxial resonator system is configured to capture microwave measurements of the sample at different temperatures and pressures after the sample is placed inside of the pressure cell, a top of the pressure cell is closed, and after the injectable medium is injected into the pressure cell in the gap.
HYDRAULIC PRESSURE TRANSMISSION DEVICE, AND PRESSURE SENSOR HAVING A HYDRAULIC PRESSURE TRANSMISSION DEVICE
A pressure transmission device includes a main part and a separating membrane secured to the main part. A pressure chamber is formed between the separating membrane and a surface, with the pressure chamber communicating with a hydraulic path. The separating membrane is: supplied with the process medium from a first membrane side; the pressure chamber and the hydraulic path are filled with a transmission fluid; the separating membrane is connected to the main part; and the separating membrane has a central region. The device additionally comprises a temperature sensor and a mount, wherein the temperature sensor introduced into the mount. The mount is arranged in a central cavity in such a way that a surface of the mount facing the separating membrane lies on a plane relative to the central region such that the surface of the mount acts as an abutment for the separating membrane when pressure is applied.
Sensor Module Having an Intermediate Pedestal on Which One or More Die Are Mounted
A sensor module includes a container. The container has a closed wall extending between a first end of the container and a second end of the container. An exterior of the closed wall at least partly defines a seal-receiving channel. The seal-receiving channel extends around a circumference of the closed wall. The sensor module also includes a pedestal positioned between the first end and the second end and at least partly defining a first compartment and a second compartment surrounded by the closed wall. The sensor module further includes a sensor die positioned within the first compartment and mounted on the pedestal.
Microfluidic pressure sensor
A microfluidic pressure sensor may include a reference chamber, a sensed volume, a microfluidic channel connecting an interior of the reference chamber to an interior of the sensed volume, a volume of liquid contained and movable within the microfluidic channel while occluding the microfluidic channel and a sensor to output signals indicating positioning of the volume of liquid along the microfluidic channel. Positioning of the volume of liquid along microfluidic channel indicates a pressure of the sensed volume.
System and method for detecting leaks in a sealed coolant system
A sealed cooling system includes a coolant tank having a liquid space configured to hold liquid coolant, and a gas space configured to hold gas. A temperature sensor detects the temperature of the liquid coolant. A pressure sensor detects the pressure in the coolant tank. A processor compares the pressure in the coolant tank to predicted pressure in the coolant tank as a function of liquid coolant temperature. The processor determines and outputs a signal indicative of a leak in the sealed cooling system if the pressure in the coolant tank deviates from the predicted pressure in the coolant tank according to predetermined criteria.
