The ultra-stable Rosemount 2240S is approved for demanding custody transfer applications, which require very accurate temperature measurements for net standard volume calculations.It can be used with a Rosemount 565, 566, or 765 temperature sensor. The Rosemount 2240S connects up to sixteen 3- or 4-wire temperature spot elements and an integrated water level sensor.It provides average liquid temperature for net volume calculation based on each individual spot temperature element in combination with the corresponding level value. It has an impressive temperature conversion accuracy of ± 0.05 °C (± 0.09 °F).
Accuracy: ±0.05 °C (±0.09 °F). Over measuring range and ambient temperature 20 °C (68 °F).
Ambient Temperature Effect: ±0.05 °C (±0.09 °F).
Measuring Range: Supports -200 to 250 °C (-328 to 482 °F) for Pt-100.
Resolution: ± 0.1 °C (± 0.1 °F) according to API chapter 7 and 12.
Number of Spot Elements: Up to 16 RTD spot elements:• 3-wire common return or individual wiring.• 4-wire individual wiring.
Sensor Type: Supports Pt-100 (according to IEC/EN60751, ASTM E1137) and Cu-90.
Communication Protocol: Foundation™ Fieldbus for connection to Rosemount 2410 with self-configuring Tankbus or any Foundation™ Fieldbus host system.
Custody Transfer Approval: OIML R85:2008, and national certifications such as PTB, NMi etc.
Emulation Capability: Possible to integrate with legacy tank gauging systems.
Metrology Sealing: Supports emulation of other vendors’ communication protocols: E.g. Enraf, L&J Tankway, Varec Mark/Space, Whessoe, GPE, Sakura and Tokyo Keiso.
Power Supply: • FISCO: 9.0 - 17.5 VDC polarity insensitive (for example from 2410 Tank Hub).• Entity: 9.0 - 30.0 VDC polarity insensitive.
Ambient Temperature: -40 to +70 °C (-40 to +158 °F).Minimum start-up temperature is -50 °C (-58 °F).
