Pressure Transducers
QPress – QOM-CERAMIC 5500 Series
The QOM-CERAMIC 5500 Series is a ceramic-element OEM pressure transmitter for corrosion-resistant duty. A dry ceramic capacitive sensor with on-board ASIC conditioning measures 0-10 to 0–60 bar with stable, repeatable output, and the wetted ceramic diaphragm resists aggressive and abrasive media that attack metal sensors. Analogue outputs plus an I2C digital interface, a choice of compact process connections and an IP65 housing make it a flexible building block for OEM equipment and water and utility duty.
