Sensor Technology:

Phaze uses sensors that are sealed in Benestad’ s glass/ceramics-to-metal sealing process. The advantages with sensors made from this process are many:

• Stable material properties overe time: Glass is an in-organic material which will not deteriorate and change material properties over time.

• Hermetically sealed surface. The glass/ceramics is chemically bound to the sensor housing.

• No diffusion of liquids or gas. The glass/ceramic has a cross-bound structure that ensures high pressure rating (200 000 psi/14 000 bar) and high temperature properties (1200°F/650°C).

• Erosion and corrosion resistant. The material has been exposed to well stream for more than 15 years.

This ensures an extremely reliable sensor over time.

Electrical termination – signal penetrator + bootseal:
Phaze uses only glass/ceramic-to-metal sealed signal penetrators. The termination point  is electrically protected to the environment with bootseals. The glass/ceramic-to-metal penetrator is an excellent pressure barrier and the bootseals provides the best electrical integrity over time.

Capacitance:
A capacitor consist of two electrodes that are separated by a medium. Capacitance describes how the two electrodes responds to  voltage difference applied to them.The capacitance is proportional to the dielectric constant of the media.
