Chuck pressure transmitter with high precision

1、 Performance Usage

MS-3051GP/DP/DR pressure transmitterTwo line input/output isolation, anti-interference. By using digital technology to compensate for the temperature and nonlinearity of the sensor, the accuracy and range of the sensor have been greatly improved. The instrument has a HART communication interface, which can be equipped with a configuration and debugging system for testing, configuration, and calibration in calculations. It can also be configured and calibrated on site with a handheld controller (compatible with ROSEMONT275).Suitable for measuring pressure, differential pressure, and absolute pressure of various liquids, gases, and vapors.

2、 Technical parameters

◆ Target audience: liquids, gases, or vapors
Measurement range: Refer to the selection specification table
◆ Output signal: 4-20mAVDC. Overlay with HART protocol digital signal
Power supply: External power supply 24VDC. (Power supply range 12V-45V)
Range ratio: 40:1
Accuracy: Range of 3, 4, 5
When the range ratio is 1:1 to 10:1, it is ± 0.1% of the calibrated range
When the range ratio is 10:1 to 40:1, it is ± 0.05 (1+0.1URL/range)% of the range
The range is 6, 7, 8, 9, 0
When the range ratio is 1:1 to 10:1, it is ± 0.15% of the calibrated range
When the range ratio is 10:1 to 40:1, it is ± 0.075 (1+0.1URL/range)% of the range
Stability: ± 0.15% of the measuring range for 6 months.
◆ Temperature influence: The zero temperature error is ± 0.25/55 ℃ of the measuring range; The total temperature error, including zero and range, is ± 0.5/55 ℃ of the range
◆ Attention: Double the temperature impact error for ranges 3, 9, and 0
Static pressure influence: (DP type in linear output) Zero point error: with a static pressure of 10MPa, the zero point error of ranges 4 and 5 is ± 0.25% of the range, and the zero point error of ranges 3, 6, 7, and 8 is ± 0.5% of the range. This is a system error. Before installation, the zero point of the transmitter can be adjusted according to the actual static pressure to eliminate this error. Zero point error (HP type in linear output): with a static pressure of 31.2MPa, the zero point error is less than ± 2.0% of the range. This is a system error. Before installation, the zero point of the transmitter can be adjusted according to the actual static pressure to eliminate this error.
Power supply impact: less than 0.005%/V of the output range.
Vibration effect: In any axial direction, at a frequency of 200Hz, the error caused is ± 0.05%/g of the measurement range.
◆ Load impact: As long as the voltage of the input transmitter is higher than 12V, there is no load impact in the load working area.
Installation position impact: A zero point error of no more than 0.25kPa is generated, which can be eliminated through calibration without affecting the range; The relative rotation of the measuring body to the flange has no effect
