Intelligent differential pressure transducer with scalable measurement range

"Intelligent differential pressure transducer with scalable measurement range" by halstrup - walcher GmbH

Demands for increased quality in nearly every area of industry have subjected pressure gauges to sophisticated demands as well. These include clean room monitoring and the ability to monitor sterile environments in the packaging machines used in products for such industries as foods and pharmaceuticals. The new P 26 differential pressure transducer from halstrup-walcher has been specially designed to meet these demands.
The P 26 is a differential pressure transducer that meets these particularly sophisticated demands. Measurement ranges between 100 Pa and 100 kPa are freely scalable from 10 to 100%, and provide the option of switching to other units of measurement like mmH2O, mmHg, etc. Cyclical self-calibration of the zero point ensures a high level of measurement stability. Two cutoff points are available that can be set freely along the entire measurement range; these allow the user to connect visual or audible alarms that would be triggered any time values fall above or below limits. All measurement values can be clearly read on an optional graphic LCD. The instrument can, if necessary, communicate with a master control unit via an RS 232 interface and can be mounted either on a wall or on top-hat rails. A hand-held unit can be used as a configurator for the one-time calibration when using more than one of the affordable P 26 pressure transducer without a display.

About halstrup - walcher GmbH

A family-owned and highly innovative supplier of customised products

halstrup-walcher GmbH has been in family-ownership ever since it was founded in 1946. The process of its growth and development has been a fascinating journey for all involved. The company traces its roots back to the area of precision mechanics for use in medical systems. CEO Jürgen Walcher looks back at the impressive rise of his business. "Since then, we have significantly changed the focus of our products. However, the precision and innovative energy of our solutions have remained a constant factor." Nearly seventy years after its founding, the medium-sized family enterprise remains true to its traditional philosophy of satisfying its customer needs and providing outstanding quality. "We plan for the long-term and think in terms of partnership. We have close and long-standing relationships not only with our customers but also with our approx. 110 employees, our local community in Kirchzarten and our suppliers."

halstrup-walcher GmbH successfully manufactures and markets products in three business areas: positioning systems for mechanical engineering applications, pressure and volume flow measurement technology for building technology and OEM customers as well as spur gears and actuators for OEM customers. The company develops and manufactures both catalogue products and customised versions of its models. The depth of expertise in the development and manufacturing of these products is remarkable. halstrup-walcher's strong quality assurance programme and lean processes have made it a highly professional supplier of customised models with impressive performance in terms of quality, costs and punctuality.

halstrup-walcher – successful in three business areas

Positioning systems

halstrup-walcher supplies positioning systems with a wide variety of geometrical forms, features and bus systems required by professional machinery manufacturers. These intelligent drives pave the way for highly flexible machinery solutions with minimal changeover times ("cyber-physical systems" for industry 4.0 concepts). Here, the market leader puts its trust in the integration of all relevant sub-systems (drive, gear, absolute position measurement, preventative monitoring functions, bus communication). The machine can be quickly and automatically adjusted to a new format with a high degree of accuracy. This ensures that customers can achieve the optimum availability of their machinery.

Pressure and volume flow measurement

halstrup-walcher offers both standard models and customer-specific solutions for high precision measurement tasks in pressure and volume flow measurement applications. In addition, the company has its own in-house DAkkS calibration laboratory for pressure, volume flow and mass flow.
halstrup-walcher develops, manufactures and sells differential pressure transmitters and system solutions for volume flow measurements of air and non-aggressive gases. These are used in applications such as air-conditioning systems and clean room technology. Regulation of air pressure in clean rooms prevents the inflow of contaminated air. In air-conditioning systems, halstrup-walcher solutions are used to monitor air filters, ventilator fans and air consumption. The company's products find further applications in the mechanical engineering sector. Examples include solutions for maintaining overpressure or vacuums in hygienic applications or for recording air volume flow. halstrup-walcher also offers customer-specific, calibrated air flow sections for this purpose.
This range of products is supplemented by high precision calibration devices and absolute pressure transmitters.

Spur gears / Actuators

halstrup-walcher offers a complete range of spur gear and actuator solutions.
These drives for performing linear or rotating adjustments / movements are always developed for optimum use of the available construction space and a consistently high level of precision; drives with or without housing, as a motor / gear combination, with additional options such as regulation or a simple control module (analogue or digital).
Developing of mechanical designs and electronics and all the relevant stages of the manufacturing process are performed in-house – from milled gear wheels to assembled SMD circuit boards. Tailor made.
