DESCRIPTION
The 'HT' range of crystals are designed for applications subjected to
high operating temperatures. The CX1VHT/CX1HHT, CX4VHT and
CX9VHT crystals operate up to 200°C and feature an expected life in
excess of 1000 hours at these temperatures. The frequency range is:
CX1VHT and CX1HHT: 10kHz to 600kHz
CX4VHT: 30kHz to 250kHz
CX9VHT: 32kHz to 160kHz.
APPLICATIONS
Downhole instrumentation
Rotary shaft sensors
Underground boring tools
