About the CHT-2
Advanced Sensor Ceramic Hybrid Technology (CHT) 2 Series is a temperature compensated, mV output, PCB mounted pressure sensor packaged in a rugged Dual In Line package. The Ceramic Hybrid Technology uses a silicon MEMS pressure sensor bound to a ceramic substrate containing thick film resistors that are uniquely laser trimmed for each sensor. Incorporating a flexible design, the CHT-2 Series is available with short, long or no tubes and can be mounted pins up or pins down to allow OEMs to optimize their board design. The CHT-2 series is powered using a constant current and when configured as in the Application Note, the integrated gain set resistor will ensure sensor field interchangeability. The CHT-2 series superior die performance, coupled with rugged ceramic substrate ensures long term stability with superior temperature performance over wide operating range.
