Sensor blanks

Langatate (LGT) crystals possess series of important physical properties that is used in sensors of physical quantities. LGT crystals have certain advantages compared to traditional piezoelectric materials (piezoceramics and quartz) used in sensors measuring physical values.

LGT elements can be used in pressure and vibration sensors operating at temperatures up to 600 °C. Sensors capable of withstanding 900 °C are currently under development.
