LR3051LT intelligent flange installation liquid level transmitter

Intelligent flange installationManufacturer of liquid level switch controllerThe LR305lLT intelligent flange mounted liquid level transmitter is used to measure the liquid level and density containing solids and precipitating liquids, and then convert it into a 4-20mADC signal output. LR3051LT can communicate with HART and handheld devices for settings, monitoring, etc.

Performance Specifications

Zero benchmark calibration range, under reference conditions, filled with silicone oil and 316L stainless steel isolation diaphragm. )

1.1. Reference accuracy

± 0.1% calibration range

1.2. Stability

6 months, ± 0.1% URL

1.3. Environmental temperature impact

Zero point error ± 0.2% URL/56 ℃

Overall error: ± (0.2% URL+0.18% calibration range)/56 ℃

1.4. Vibration effects:

In any axial direction, the vibration effect at 200Hz is ± 0.05%) URL/g

1.5. Power supply impact:

Less than ± 0.005% output range/volt.

1.6. Load impact:

There is no load impact unless there is a change in the power supply voltage.

1.7. 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.

1.8. Impact of installation location

When the liquid level diaphragm is installed vertically, the zero drift is at most ± 0.25kPa. When installing the liquid level membrane horizontally, the zero drift is at most 1.25 kPa plus the extension length of the protruding part. All zero drift can be corrected without affecting the range.

Functional specifications

2.1. Measurement range: see selection table

2.2. Zero point and range

It can be adjusted using the local range and zero buttons, or remotely using a HART controller

2.3. 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 the zero point is deviated, the upper limit of the range must be less than or equal to+URL. The verification range must be greater than or equal to the lower limit range.

2.4. Output

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

2.5. Rated pressure limit of liquid level flange
