DESCRIPTION
The SCPA...-Series of amplified pressure
sensors use state of the art silicon micromachined
pressure sensors in conjunction with
stress free packaging techniques to provide
cost effective temperature compensated
pressure sensors and liable precision signal conditioning.
SCPA-... SERIES
Amplified Pressure Sensors
Referenced and ratiometric
Voltage Output, I 2 C-Bus Slave
On devices 5PSI above the top side of the chip is protected against humidity by a SILGEL
coating. The general design is for use with non corrosive, non ionic pressure media.
Several gases especially in medical applications can be allowed on request.
The SCPA-V-sensors provide an internal voltage referenced 0 .. 5V, 0.2 .. 4.9V or individual
calibrated Voltage ouput. The unstabilised supply voltage for the SCPA-F ranges from 9V to 24V.
The offset is precisely adjusted and needs no external potentiometer. SCPA-R works with 5V +-10%
Supply and delivers a ratiometric output signal.Standard output is 0.2 .. 4.9V but individual calibration
ranges can be provided. SCPA...I 2 C has a I 2 C-Bus interface and delivers continuously serial data
as a slave from power on or waits for a I 2 C Master’s request..
