ME770 /ME771 / ME772 ceramic pressure sensor by AMSYS

ME77X ceramic pressure sensor

The ME77X series pressure sensors are piezoceramic OEM sensors* with integrated signal processing. The sensors deliver a ratiometric* (ME770) or a non-ratiometric (ME772) voltage and a 4-20 mA (ME771) current signal for two-wire operation.

The ME77X series is available in relative pressure, absolute pressure and sealed gage * versions. The sensors are individually and fully calibrated and temperature compensated.

These OEM sensors consist of a ceramic body with an 18 mm diameter and an octagonal membrane flush on the front. The electronics are located on a circuit board that is mounted on the back of the ceramic body.

Thanks to the excellent chemical properties of the ceramic material, the pressure sensors of the ME77X series are resistant to almost all, including aggressive, media.

Accessories for the ME 77X

Optionally, stainless steel housings of type 90XD or plastic housings of type 89XD are available for the simple construction of prototypes based on ceramic measuring cells.

*Sealed gage is a kind of absolute pressure. It is used in particular to measure absolute pressure at high pressures. In contrast to absolute pressure sensors, the enclosed volume was not evacuated.
