CrystalTech, Inc. manufactures and markets two crystalline quartz pressure sensors designed for use in hostile environments. The MQPS-20 sensor is designed for precision measurement of pressures to 20,000 psi at temperatures to 200° C, while the MICRO-25 sensor is designed for pressures up to 25,000 psi. Their technology utilizes thickness-shear quartz resonators that change frequency in response to applied pressure, making them ideal for down-hole data acquisition in the energy industry. CrystalTech focuses on serving the market segment interested in designing, manufacturing, and calibrating pressure transducers for specific applications with the accuracy and resolution of quartz sensors. The company was founded by experts with extensive experience in quartz sensor design and production, emphasizing quality control and continuous improvement in manufacturing processes.
