Product Description

Each field-replaceable pressure sensor incorporates a temperature sensor and an integral EEPROM for storage of personalized calibration data as well as sensor information such as serial number, pressure range, factory calibration date. Integrating the EEPROM within the sensor enables simplified field replacement of sensors with automatic uploading of sensor data during power up. The microprocessor uses the data from the EEPROM to correct for sensor offset, span, linearity and thermal errors. The microprocessor’s digital temperature compensation algorithm reduces sensor thermal errors by a factor of ten or more over conventional sensor compensation. The microprocessor also controls the actuation of an integral manifold to execute on-line zero or span calibrations upon request.
This capability virtually eliminates sensor offset drift error and provides system accuracy errors less than ±0.05% FS (Full Scale). The Model 9916 can sample using up to three concurrent scan lists a continuous rates up to 100 measurements per channel per second in engineering units with timestamps. Pressure data in engineering units is output through an auto-negotiating 10 or 100 Mbit Ethernet interface supporting both TCP and UDP protocols. The Model 9916 data output optionally includes data time stamps derived from either the 9916 internal real time clock, NTP clock or an IEEE 1588-2008 Precision Time Protocol (PTPv2) grand master clock.
