PA-100 series pressure sensors are low range differential pressure sensors, built-in amplifiers, can measure differential pressure.
The PA-100 series are low‑pressure transducers that incorporate a compact amplifier circuit and measure differential pressure. Several variants are offered (‑100D‑S, ‑200D‑S, ‑500D‑S, and the corresponding ‑W versions) covering ranges from 0‑1 kPa up to 0‑5 kPa.
The document provides standard electrical specifications, environmental limits, and mechanical dimensions, including supply voltage, output range, temperature and humidity limits, and durability tests such as shock and moisture resistance.
