LD292
Foundation Fieldbus Pressure Transmitter
LD292 offers digital Foundation Fieldbus based communication simplifying
calibration and providing remote diagnostics. Its microprocessor-based
electronics allow for total interchangeability with SMAR capacitive
sensors, correcting automatically sensor characteristic changes caused
by temperature fluctuation.
Some Characteristics:
Output |
Digital only. Complies with IEC 61158-2:2000 (H1): 31.25 kbit/s voltage mode, bus powered. |
Range |
0 to 25 MPa (3600 psi) |
Rangeability |
Accepts calibration from URL to URL/40 |
Accuracy |
± 0.075% of calibatred span |
Power Supply |
Bus powered: 9 to 32 Vdc.
Quiescent current consumption: 12 mA
Output impedance: nonintrinsic safety from 7.8 kHz - 39 kHz should be greater or equal to 3 kOhm.
Intrinsic safety output impedance (assuming an IS barrier in the power supply) from 7.8 kHz - 39 kHz should be greater or equal to 400 Ohm. |
Update Output Current |
100 ms |
FMEDA |
Analysis done by Exida |
MTBF |
239 years |
SIL |
Yes |
Calibration |
With reference and without reference |
Access Protection |
Yes, by hardware |
Diagnostic |
Yes, by LCD |
Indicator |
Optional 41/2-digit numerical and 5-character alphanumerical LCD indicator |
Only Electronic Board |
Only electronic board with math co-processor high-performance, interchangeable on all models. |
Update for HART and PROFIBUS PA |
These protocols are easily changed by either replacing the
internal electronic board or downloading the firmware. A
FOUNDATION fieldbus transmitter can be changed into a HART device by replacing the internal card, and vice versa. A FoundationTM fieldbus device can be changed into a PROFIBUS PA device
and vice versa, by simply downloading a new firmware. |
