Pressure Sensor Delivers 4.5 VDC Output
Requiring a 5 VDC power supply, Kavlico’s P6050 PCB mount pressure sensor dispenses a standard analog linear amplified output from 0.5 VDC to 4.5 VDC proportional to pressure. The piezo-resistive sensing technology-incorporating unit allows for the selection of a standard voltage output device or alternative digital SPI output with an embedded 10-bit analog-to-digital converter. The temperature-compensated sensor comes in absolute, gage or differential configurations with pressure ranges from 0” H20 to 13” H20 and from to 0 psi to 75 psi. The product measures the pressure of air and dry gases for medical applications, such as oxygen concentrators, respirators, CPAP systems, and hospital beds. The sensor has specification for vertical, horizontal, or dual horizontal pressure ports; accuracy specification of 0.5% for linearity, repeatability, and hysteresis at 25°C; and 2% total error band from 0°C to 65°C.
