Fully automatic cleaning control.

The range of functions of Exner Process Equipment's EXmatic 470 cleaning control for the automation of pH measuring points has been expanded.

One special feature of the system offered by this equipment is its openness, that means the cleaning control is not tied to a specific manufacturer of pH sensors or transmitters. Operation of the EXmatic 470 is also very easy for the user thanks to a clear menu structure and the use of a touch-sensitive color display. As an alternative to this, a wireless network connection together with a mobile device can also be used for the parameterisation.

In addition to the freely programmable cleaning cycles with up to three different media, a definable pause time and operating modes as well as a switchable sealing water function, the EXmatic 470 is now available with a so-called measuring time delay. This makes it possible to delay the signal output by the control until the measured value of the sensor in the process medium has stabilized. A "Measure" signal is only output after the set time has elapsed.

The EXmatic 470 is used in a wide variety of areas. For example in water and wastewater treatment, in the paper and sugar industry and in thermal power stations.

Clean pH probes.

Through the combined use of an automatic cleaning control unit and a retractable probe housing, the necessary maintenance steps on pH sensors can be minimised.

The option of controlling all pneumatically operated retractable probe housings of Exner's EXtract series fully automatically is given with the EXmatic 470 cleaning control unit.

Compared to conventional, permanently installed measuring points, retractable housings offer the system operator many advantages. Used correctly, for example in pH measurement technology, maintenance work at the measuring point is significantly reduced, the service life of the sensors used is extended and the reliability and availability of the measured value are increased. An efficient cleaning control is of essential importance for the safe and economical automation of the retractable probe housings.

Operation of the EXmatic 470 is very easy for the user thanks to a clear menu structure and the use of a touch-sensitive color display. Optionally, a wireless network connection together with a mobile device can also be used for parameterisation.

New Servo Press Module for clean room applications uses wireless

Suitability for use in cleanrooms to ISO standard and wireless telemetry of the force signal are just two of the outstanding attributes of the new Kistler Type 2157B NCFT electromechanical, servo press module. These new features make the new module particularly suitable for use in processes with small test and joining forces, such as sensitive press-fit operations and test routines in the medical and precision product sectors.

The compact mechanism, integral piezoelectric force monitoring in the ram and two predefined measuring ranges from 0.05 kN to 1.5 kN make the new modules ideal for use in assembly and joining processes monitored by force-vs-displacement. Advantages include easy selection of the ideal measuring range, a high overload factor and modest user spare parts inventory. Complex drive profiles with a maximum speed of 400 mm/s and displacement repeatability of 0.002 mm can be achieved.

The new NC servo press module provides ultra-high precision measurement of extremely small forces directly on the tool holder under actual process conditions, without the need to mount a sensor on the ram. This eliminates any possibility of the measurement signal being impaired by dynamic characteristics of masses or moving cables.

Many medical consumables are required to be manufactured under cleanroom conditions. The NC joining module Type 2157B meets the stringent, cleanroom production environment requirements defined by ISO 14644-1 Class 8 as standard and Class 7 conditions can be met with minor adaptation.
The new NCFT augments the range of NC servo press systems from Kistler. Five series now provide seamless coverage of measuring ranges from 0.05 to 600 kN. They are available not only as a system subassembly but also as complete manual workstations for development, prototyping or small-batch production.
