CHT-3 mV Compensated, Constant Voltage, DIP Pressure Sensor

About the CHT-3

Advanced Sensor Ceramic Hybrid Technology (CHT) 3 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-3 Series is available with no, short or long 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 voltage and when configured as in the Application Note, the integrated current set resistor will ensure sensor field interchangeability. The CHT-3 series superior die performance, coupled with rugged ceramic substrate ensures long term stability with superior temperature performance over a wide operating range.
