SD Intelligent flange pressure transmitterDetailed product description：

Characteristics of SD intelligent flange pressure transmitter

When used for differential pressure and level measurement of media, the process medium and transmitter should be isolated, and different corrosion-resistant materials should be selected for measuring media with different properties
Output signal: 4-20mA linear, two-wire system
Component welding structure, strong reliability
Low volume design of filling chamber to reduce temperature impact
According to user requirements, the filling solution can be selected
Accurate and stable measurement, flange installation
Measurement accuracy: 0.2 level

Technical parameters of SD intelligent flange pressure transmitter

Reference accuracy: ± 0.1% calibration range
Stability: 6 months, ± 0.1% URL
Environmental temperature impact:
Zero point error: ± 0.2% URL/56 ℃
Overall error: ± (0.2% URL+0.18% calibration range)/56 ℃
Vibration impact:
In any axial direction, the vibration effect at 200Hz is ± 0.05% URL/g
Power supply impact: less than ± 0.005% output range/volt.
Load impact: There is no load impact unless there is a change in the power supply voltage.
Electromagnetic interference/radio frequency interference (EMI/RFI impact):
When the field strength reaches 30V/M from 20 to 1000MHz, the output drift is less than ± 0.1% of the range.
Zero point and range:
It can be adjusted using the local range and zero buttons, or remotely using a HART controller
Zero point positive and negative transfer:
When zero point negative shift occurs, the lower limit of the range must be greater than or equal to - URL; When zero point is shifted forward, the upper limit of the range must be less than or equal to+URL. Verify that the range is greater than or equal to the minimum range.

output:
4～20mA DC， Users can choose linear or square root output, and the digital process variable is superimposed on a 4-20mA DC signal, which can be used by upper computers using the HART protocol.
