MEASURING, CONTROLLING, REGULATING WITH BUILT-IN INTELLIGENCE: HSW FLOW INSTRUMENTATION

Product catalog summary
Introduction
Henke-Sass, Wolf (HSW) provides high-quality flow instrumentation products adhering to Total Quality Management and DIN EN ISO 9001 standards. These products ensure batch traceability and undergo intensive production checks, supported by modern production lines and skilled employees.
Product Features
HSW flow instrumentation is known for its reliability and flexibility, suitable for various industrial applications such as smelting, vacuum, sealing, and sinter furnaces, as well as water treatment, heat exchangers, compressors, and turbines. Some products are available in ATEX versions.
Measuring Principles
HSW employs several measuring principles to ensure reliable results:
  • Mechanical Pendulum Principle: Uses a measuring plate that changes position based on flow velocity.
  • Contactless Pendulum System: Utilizes a permanent magnet for signal transmission to a reed switch.
  • Pendulum System with Magnetic Resetting: Uses repelling magnets for resetting.
  • Pendulum System with Progressive Resetting Force: Features a progressive spring system for enhanced dynamics.
  • Paddle Wheel Principle: Generates a digital, flow-dependent signal.
  • Piston Measurement Principle: A spring-held piston with a permanent magnet triggers a reed switch.
  • Ultrasonic Method: Measures flow velocity based on sound delay time.
  • Calorimetric Principle: Monitors medium temperature with heat output proportional to flow velocity.
Product Range
The document lists various flow switches and transmitters with features like adjustable switch points, sensor technology without moving parts, and different output options. These products are designed for diverse applications, offering high precision and reliability.
Conclusion
HSW's flow instrumentation combines intelligence with efficiency, offering high technical know-how and top quality. The products meet the demands of various industrial sectors, ensuring reliable and precise flow measurement and control.
Specifications
  • DW-K: Suitable for low switching points, robust design, position-independent, handles pressures up to 25 bar and temperatures up to 100°C.
  • DW-L: Inexpensive, flexible, made of plastic to prevent corrosion, with easy adjustment of switching points.
  • DW-R: Versatile, operates on a contactless pendulum principle, resistant to contaminated media, offers low pressure loss.
  • DW-N: Features adjustable switching points and optical switching display, resistant to contamination and magnetic fields.
  • DW-U: Similar to DW-N but includes an analogue display of the current flow rate.
Technical Data
  • Switching capacities and maximum pressures vary across models, with higher specifications available on request.
  • Temperature ranges generally up to 100°C, with ambient temperatures up to 70°C.
  • Protection types include IP55 and IP65, with Ex versions available for hazardous environments.
ApplicationsThese devices are used for monitoring lubricant, coolant, and water circulation systems, with some models suitable for gases upon request. They are robust, reliable, and easy to maintain, with customization options to meet specific operational needs.
Flow Transmitters and Sensors
  • DW-FS and DW-FS-AV Series: Operate on the paddle wheel principle, providing a 4-20 mA or frequency output signal. DW-FS is an inline variant, while DW-FS-AV is welded onto larger pipelines.
  • DW-S Ultrasonic Flow Transmitter: Utilizes ultrasonic sensors for high precision and dynamic measurement, with no moving parts and excellent long-term stability.
  • DW-SM Ultrasonic Flow Transmitter: Similar to DW-S but without a display, featuring an integrated USB interface for easy programming.
  • DW-T Flow Sensor: Operates on the calorimetric principle, ideal for monitoring flows with minimal pressure loss, featuring an integrated USB interface for configuration.
Special SolutionsHenke-Sass, Wolf offers customized solutions for specific requirements, leveraging their development platform and production expertise to address technical challenges and customer needs quickly.
