DPR-2200

Product catalog summary

Product Overview
The DPR-2200ALW is a SMART Differential Pressure Transmitter designed for measuring differential pressure, level, and flow. It is suitable for corrosive environments and resistant to chemical attacks. Key features include high accuracy (±0.1%), 4-20mA analogue with digital communications, HART compatibility, and ATEX certification for intrinsic safety and flameproof environments.

Applications
This transmitter is used for measuring pressure differences in gases, vapors, and liquids, particularly where diaphragm seals are needed. Typical applications include hydrostatic level measurement in closed tanks, density, and phase boundary measurements.

Key Features

High accuracy of ±0.1%
4-20mA analogue with digital communications
HART compatibility
Static pressure limit up to 420 bar
ATEX certified for intrinsic safety and flameproof environments
Fully welded sensor for long-term usage
Local configuration of measuring range

Configuration & Communication
The transmitter can be configured using a KAP-03 communicator or a PC with RS-HART converter and Delta D-Soft software. It allows changes in metrological parameters such as pressure units, range start and end points, and time constant.

Measuring Ranges
The nominal measuring range varies from -160 to 160 mbar up to -1.6 to 16 bar, with a static pressure limit of 40 bar. The transmitter can be configured to compensate for ambient temperature effects.

Recommendations
For hydrostatic measurements, it is recommended to use identical diaphragm seals at both upper and lower connection points. Optimal results are achieved using specific diaphragm seals like DN 80, DN 100, A 109, and S-Comp.

Ordering Information
Model codes and descriptions are provided for different configurations, including casing options, output signals, and static pressure limits. Special versions and certificates are available, such as EExia for intrinsic safety and EExd for explosion-proof environments.

Installation & Use
Instructions are provided for configuring the transmitter to measure liquid levels and densities. The process involves setting the transmitter in its working position, making electrical connections, and using HART communication for configuration.

Specifications and Calculations
The document provides a method to calculate the measurement range for a DPR E-2200 transmitter used to measure phase boundary height between liquids of different densities. An example involves calculating the start and end points of the measurement range for liquids with densities of 0.7 g/cm³ and 1.0 g/cm³, with a vertical seal spacing of 1600 mm. The sealing system uses DC-550 oil with a density of 1.068 g/cm³. The start of the measurement range is determined by calculating the pressure difference when the tank is filled with the lighter liquid, resulting in -588.8 mm H₂O. The end-point is calculated by adding the pressure increase from a 1-meter column of the heavier liquid, resulting in -288.8 mm H₂O.

Additional Remarks
Adjustments to the transmitter settings may be necessary based on laboratory density measurements, especially in pipeline segments with high flow velocity. Increasing the vertical spacing of diaphragm seals can widen the range and improve accuracy. The maximum vertical spacing depends on the transmitter's basic range and the density boundary values of the measured liquid.

Example Calculation
An example is provided for determining the maximum vertical spacing of seals for a DPRE-2200 transmitter measuring liquid density between 0.6 and 1.2 g/cm³, using AK-20 silicone oil with a density of 0.945 g/cm³. The lower boundary of the range is -10 kPa (-1020 mm H₂O), and the upper boundary is +10 kPa (1020 mm H₂O). The conditions are satisfied when the seal spacing is not more than 2957 mm.

To simplify the mathematical operations, we introduce the density coefﬁcient of the medium, Xr . rmedium [g/cm] 3 r water at 4 °C [g/cm 3 ] 3 Since the density of water at 4°C is 1 g/cm , the density coefﬁcient Xr is numerically equal to the density of the medium expressed in g/cm3 . To determine the hydrostatic pressure of a column of liquid in mm H2O, it is sufﬁcient to multiply the height of the column h [mm] by the density coefﬁcient of the liquid Xr. Since it is easy to determine the hydrostatic pressure in mm H2 O and the transmitter can be conﬁgured in those units, in the descriptions...
