High Precision Differential Pressure Sensor DPH100 Type

The ICS‑NH DPH 100 Series Differential Pressure Sensor is a robust SOI (Silicon‑on‑Insulator) based differential pressure sensor engineered for reliable performance over an exceptionally wide temperature range. Built with a 316L stainless steel housing and diaphragm, the sensor delivers accurate and stable differential pressure readings from 0 kPa up to 400 kPa, with a fast electrical response time of under 1 millisecond. Its isolated construction and wide supply voltage range from 3 V to 20 V DC make it suitable for integration into diverse industrial and scientific systems. The device has been tested to meet vibration standards defined in DO‑160 Cat. H and R, offering enhanced reliability in demanding environments. Typical outputs include high‑resolution millivolt signals with excellent repeatability and linearity across the operating range.
