LD292
Foundation Fieldbus Pressure Transmitter

DT300 Series - Transmissores de Densidade

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.
