AH3 Gauge Pressure Sensor Analog Output & Threshold Detection
Pressure Medium: Air/Gas
Sensor Type: Gauge, Differential
Supply Voltage: Under 5V, 5V
Output Signal: Voltage
Pressure Range: 4” H2O to 3 psi, 3-300 psi
Kind: Board Level

The AH3 gauge pressure sensor series has a smooth analog amplified and temperature-compensated output with low noise. The AH3 has a unique single point pressure threshold detection. 

Analog output and threshold voltage are supplied to an internal comparator that compares two voltages and outputs a comparison result as a digital output. Narrow dual inline package with a single horizontal port, the AH3 sensor is excellent for medical devices, industrial pneumatic devices and consumer applications.
