This document describes the features of the silicon piezoresistive absolute pressure sensors KPY 52-A and KPY 56-A in the stainless steel package semiconductor group. These sensors have low pressure and temperature hysteresis, fast response, high sensitivity and linearity, high long term stability, and a built-in silicon temperature sensor.
The KPY series are silicon piezoresistive absolute pressure sensors with a monocrystalline silicon diaphragm for high load‑cycle stability. They feature low pressure and temperature hysteresis, fast response, high sensitivity and linearity, and include an integrated silicon temperature sensor. The sensors are supplied in a stainless‑steel package suitable for media‑compatible applications.
Technical data include pressure ranges from 0‑0.6 bar (KPY 52‑A) up to 0‑25 bar (KPY 56‑A), a 12 V supply voltage, bridge resistance of 4‑8 kΩ, and typical sensitivities between 0.88 mV/V and 11 mV/V. Operating temperature spans –40 °C to +125 °C, with detailed temperature coefficients for voltage and resistance provided in the electrical characteristics tables.
