Power Supply: Requires 12.5 to 45 VDC for operation, 17.4 to 45 VDC for HART® communication.

Order Details: Provides detailed order codes for different configurations, including model versions, materials, calibrated spans, and additional options like diaphragm seals and manifold valves.

Measuring Range Limits: Outlines the measuring range limits for PAD-D, -F, -G, and -H models, with specific values in mbar, bar, and other units. Special measuring spans are available upon request.

Unit Conversion: Includes a table for converting range codes into various units such as bar, kg/cm², KPa, psi, in H2O at 4°C, mm H2O at 4°C, and in Hg at 0°C.

Technical Specifications: Details the material, pressure rating, temperature range, and weight for manifold valves and other components. For example, the 2-way manifold valve is made of AISI 316/L, with a pressure rating of 6,000 psi.

Manifold Valves: Information on 2-way, 3-way, and 5-way manifold valves, including material, pressure rating, temperature range, weight, and mounting configurations with the PAD.

Dimensions and Diagrams: Includes detailed dimensions for various components and configurations, along with wiring diagrams and mounting options.

Diaphragm Seal Models: Specifications for diaphragm seal models, including size codes, diaphragm diameter, maximum medium temperature, and span ranges. Accuracy is noted as 0.075% of the calibrated span plus the influence of the seal.

Procedures: Outlines procedures for ordering and configuring diaphragm seals with the pressure transmitter, including specifying models for high and low-pressure ports, capillary lengths, and height adjustments.

Standards and Norms: References several standards for connections, ensuring compatibility with industry norms.

Recommendations: Provides recommendations for selecting filling liquids based on operating temperature ranges.

Key Data from Tables: Tables provide critical data such as diaphragm diameters, maximum medium temperatures, and pressure spans for each model.

Critical Information: Emphasizes the accuracy of the pressure transmitter and notes specific model requirements for diaphragm seals.

Limitations: Includes disclaimers about potential errors and changes without prior notice, highlighting the importance of verifying specifications before use.

Differential Pressure Transmitter Model PADSensor Inputs The models PAD - D, - G, and - H are available in a differential pressure sensor of a capacitance type. The capacitance pressure sensor measures differential and gauge pressure and is commonly used in flow and level applications. Both sides in the capacitance sensor transmit process pressure from the process isolators to the sensor. The model PAD-A is also available in an absolute pressure sensor of a piezoresisti-ve type and measures absolute pressure. The sensor module converts the capacitance or the resistance to the digital value. The...
