ESS502I/V/IIC Flush Ceramic Pressure Sensor Module

ESS502I-V-IICFlush Ceramic Pressure Sensor Module

The ESS502I-V-IIC Flush Ceramic Pressure Sensor Module is crafted with a ceramic base plate and a flush diaphragm sensor cell (ESS502), operating on the piezoresistive principle. The Wheatstone bridge is screen printed on one side of the flush ceramic diaphragm, which is subsequently adhered to the sensor’s body. The bridge faces inward toward a cavity.

Signal conditioning electronics are directly integrated on the ceramic substrate, generating a 0.5…4.5 V ratiometric output (ESS502-V), a 4-20mA output (ESS502-I), or an I2C output (ESS502-IIC) that includes both pressure and temperature data.

Power supply10-36V5V2.7-5.5V
Signal output4-20 mA0.5-4.5VI2C

Electronic calibration is conducted with the on-board ASIC, ensuring offset and span correction across temperature variations. Software for zero correction, compensating for offset shifts due to final customer assembly, is available upon request. This feature ensures precise measurements and long-term stability.

Owing to the exceptional chemical resistance of Al2O3 ceramic, the ESS502I-V-IIC Flush Ceramic Pressure Sensor Module is apt for use with almost all aggressive media.
