1. General Introduction
Emerson 2240S Multi-input Temperature Transmitter is approved for demanding custody transfer applications, which require very accurate level and temperature measurements for net standard volume calculations. 2240S can connect up to 16 three or four wire temperature spot elements and an integrated water level sensor. The value from each individual spot temperature element, in combination with the level value from the radar gauge is used for average liquid temperature calculation. It has an ultra high temperature conversion accuracy of ±0.05℃ (±0.09℉), supplies measured data to the Tankbus, which utilizes the FOUNDATION fieldbus communication protocol. The IP 66/67 and Nema 4X certified robust design makes it
suitable for installation in harsh environments. The water level sensor is factory calibrated. If any adjustment is necessary during installation, it can easily be done with the 2240S built-in on-line calibration feature.
