Piston diaphragm dosing pumps are particularly precise and pressure-independent dosing devices. The dosing quantity changes proportionally to the stroke length and can be set reproducibly down to the smallest quantities. For this reason, twin and multiple piston pumps are particularly suitable for precise mixing tasks in which a constant ratio of different media, which can be set as required, must be metered. The total quantity can be infinitely varied from 5% to 100% at a constant ratio using externally adjustable drive motors. Heated heads allow the dosing of cold, rigid media. An optional flushing lantern can be used to prevent harmful leaks and to protect the packings and pistons against abrasive substances.

We can provide you with a series of special pressure relief systems to ensure the safe handling of pressure loads and stress such as encountered as a result of technical interference (e.g. accidental arcing) emanating from internal malfunction of the plant. Different versions and functionalities enable optimum adaptation to suit the respective technical building. Designs: Pressure relief vanes which close or open in the case of excessive pressure (to ensure IP 23-DH degree of protection with an upstream ventilation element) Pressure relief coupling Contiguous pressure relief valves, opening upwards or downwards Pressure relief flues Pressure relief domes Options: Special design for pressure relief vanes: Actuator for controlling air circulation (manual or motor-powered actuation via thermostat or hygrostat); Pressure relief function ensured in every operating position Our DRO and DÜA special roofs offer an ideal supplement or a separate relief option.

Our ventilation systems ensure that an optimum air exchange is achieved within technical buildings (e.g. for cooling transformer and low voltage rooms) and prevent penetration by snow, rain and insects. Individual elements can be flexibly adapted to suit building conditions and are suitable for integration in both doors and walls.

This differential pressure transmitter in a control panel housing is suitable for use as a 2- or 3-point controller thanks to its two integrated limit contacts. These permit the realisation, e.g. of ventilation controls, at low cost and without the need for additional electronics. Both the threshold values and the hysteresis for the controller are easy to set via the front keyboard. The display provides readings of measurement values directly on-site in Pa, kPa, inchH2O or mmH2O as well as information about the output states of the limit contacts. An adjustable time constant (up to 10 s) allows the instrument to generate an attenuated output signal, even under fluctuating pressure conditions. Cyclical self-calibration of the zero point ensures a high level of measurement accuracy. The instrument is available with an ISO factory calibration or DAkkS calibration certificate (optional).

To ensure that an instrument provides accurate measurements, regular calibrations are necessary. Calibration means to operate a target-performance comparision using a measuring instrument and a traceable reference. Calibration of instruments is essential in every area where sensitive measurement technology is used, e.g. in the manufacturing of sensors. It is the only way to guarantee quality standards and prevent defects arising in processes and products from the outset. For companies wanting to attain ISO 9001 certification, regular calibration of testing equipment is a requirement. halstrup-walcher has been accredited by the German calibration service DKD and Deutsche Akkreditierungsstelle GmbH (DAkkS) as a calibration laboratory in accordance with DIN EN ISO / IEC 17025 since 1999 – among other things for calibration of pressure measurements.

The portable, battery-operated KAL 84 calibration system combines a pressure transmitter and pressure gauge. These can be used to test and calibrate pressure sensors and other pressure gauges for low pressures both quickly and easily. A high degree of accuracy and excellent reproducibility of results combined with a robust design give the system all the functionalities required for laboratory and service applications. Calibration in mmHg (optional) makes the system ideal for applications in accordance with the regulations for users of medical products, e.g. blood pressure monitors and infusion/suction pumps.

The AD / BA 1000 absolute pressure transmitter is designed to display barometric pressure. At the heart of the unit is an evacuated measurement cell made from an elastic copper material.The deflection of the measurement cell due to atmospheric pressure is measured inductively without making contact. The transducer emits an electrical output signal proportional to the pressure. The device can be powered using a 24 VDC power supply or a variety of AC voltages. The instrument is available with an ISO factory calibration or DAkkS calibration certificate (optional).

The KAL 100 / 200 calibration device combines a pressure transmitter and pressure gauge. These can be used to test and calibrate pressure sensors and other pressure gauges for low pressures both quickly and easily. The desired pressure is indicated on the digital display and pressure is generated quickly and precisely through the use of a closed loop, thereby eliminating the need for an external pressure generator.

Pressure relief devices for liquid-immersed transformers open in case of an internal fault and guarantee that the occured overpressure can properly release. Pressure relief devices close with decreasing pressure back to completely closed and leaktight position. Pressure relief devices for transformers can be installed in any position or inclination on the cover or the wall of a transformer. Upon request a transformer can be equipped with several pressure relief valves.
