Product catalog summary

Overview

The DDS series pressure transmitters utilize thin film strain gauge technology for relative and absolute pressure measurement in low to medium pressure ranges. They are suitable for gaseous and liquid media, including highly viscous and crystallizing substances when equipped with a flush diaphragm. The devices comply with the Pressure Equipment Directive 97/23/EC.

  • Pressure Connection: Stainless steel 1.4571 (316 Ti), options include G1/2B per EN 837-1, G3/4B with flush diaphragm, and G1/4 female thread
  • Sensing Element: Stainless steel 1.4545 (15-5PH) with thin film strain gauge measuring bridge
  • Pressure and Overpressure Ranges: Wide range from 0-2.5 bar up to 0-2500 bar with corresponding overload limits (see detailed table)
  • Electrical Connection: Standard EN175301-803 Form A angled plug (L-plug), with options for cable connections and various connector types
  • Output Signals and Power Supply: 4-20 mA (2-wire) with 7.5-30 V DC supply; 0-10 V (3-wire) with 12-30 V DC supply; load and burden specifications provided
  • Response Time: Less than 10 ms
  • Power Consumption: Maximum 0.75 W
  • EMC Compliance: Directive 2004/108/EC, EN 61326 (Group 1, Class B emission and industrial immunity)
  • Temperature Ranges: Storage: -40 to +100 °C; Medium: -25 to +80 °C; Ambient: -20 to +70 °C
  • Accuracy (per IEC 61298-2): Linearity, hysteresis, and repeatability <0.3% FS; BFSL <0.2%
  • Temperature Influence: Mean temperature coefficient of zero and span <0.2% FS per 10 K
  • Weight: Approximately 0.24 kg

Pressure Range and Ordering Information

The transmitters are available in multiple pressure ranges from 0-2.5 bar up to 0-2500 bar, each with specific overload limits ranging from 9.2 bar to 3000 bar. Various configurations include flush diaphragm or female thread connections and output signal types (4-20 mA or 0-10 V). Each configuration has a unique order number for easy identification.

Accessories and Optional Extras

  • Temperature decouplers with various thread types (G1/2B, G1/4B, NPT 1/4, NPT 1/2) and sealing options (sealing rings, O-rings, sealing cones)
  • Welding adapters for EN 837-1 connections and flush diaphragm versions, made of stainless steel 316Ti
  • Electrical connectors including angled plugs (EN 175301-803 Form A), M12 x 1 plugs, bayonet connectors (DIN 72585), AMP Superseal, AMP Micro Quadlock, and Deutsch DT04-3P connectors with 2-wire or 3-wire configurations

Electrical Connection Details

Pin assignments and wiring details are provided for all connector types, specifying supply voltage (Ub+), ground (Ub-), output signal (S+), and shielding (Pin 4). The devices support both 2-wire and 3-wire configurations depending on the output signal type.

Compliance and Standards

The DDS pressure transmitters conform to relevant European directives and standards including the Pressure Equipment Directive 97/23/EC, EMC Directive 2004/108/EC, and IEC 61298-2 for accuracy. The devices are designed for industrial environments with appropriate protection and electromagnetic compatibility.

Summary of Critical Parameters and Best Practices

  • Ensure correct selection of pressure range and connection type based on application media and pressure levels.
  • Use flush diaphragm versions for highly viscous or crystallizing media to prevent clogging and ensure accurate measurement.
  • Observe temperature limits for storage, medium, and ambient conditions to maintain device integrity and accuracy.
  • Follow wiring and connector specifications carefully to ensure proper electrical operation and signal integrity.
  • Consider optional accessories such as temperature decouplers and welding adapters for installation flexibility and protection.
