Crystal Technology

Pressure calibration used to involve delicate and careful measurements with manometers or deadweight testers. This was never practical or reliable in the field due to environmental factors and changes.

Crystal Engineering was founded and used the combination of two emerging technologies both based on silicon: Large scale integrated circuits (LSI) and MEMS (micro-electromechanical systems) pressure sensors. This enabled Crystal to design and develop digital pressure calibrators and gauges that are portable and easy to use but with better accuracy and reliability for field use.

LSI allowed low cost analog to digital conversion, as well as low power (i.e., battery) operation, while the silicon sensors offered incredible repeatability, also at very competitive costs.

Our core technology is based on MEMS (micro-electromechanical systems) pressure transducers. The silicon in silicon pressure sensors are a crystalline structure (hence our name: Crystal Engineering). Unlike metal, crystalline structures have virtually unmeasurable hysteresis, and are manufactured using methods similar to semiconductors, with the addition of micro-machining to fabricate the sensing diaphragm. These silicon based sensors are highly repeatable, but sensitive to temperature, and somewhat non-linear.

Combining the silicone pressure sensors with digital signal processing techniques, and the result is very accurate pressure measuring equipment that’s very linear, and not affected by temperature.

Our products are very accurate. Our specifications are in “% of reading” (just like most digital multimeters and deadweight testers) instead of a “% of full scale”. This means that any one of our digital pressure gauges or pressure calibrators can replace several ordinary mechanical gauges or competitive calibrators. Saving you time and money of maintaining equipment.

Crystal Engineering designs, manufactures and services all its products. Crystal Engineering pioneered features like full temperature compensation and “% of reading” rated pressure gauges, calibrators and modules.
