With their constant processing design, CSC type continuous screen changers are able to meet the most stringent quality requirements for melt filtration. The type HSC, FSC and DSC discontinuous screen changers are a simple, robust, and affordable alternative for applications where a short interruption in the melt flow is possible for making screen changes.
The DV continuous divert and dump valve was developed specifically to meet the requirements of underwater pelletizing. It features a unique design that provides bump-less changeovers and eliminates the possibility of a deadhead condition.

Hall-effect sensors
Hall-effect sensors are suitable for proximity rotational speed recording on gears with a small module and high resolution. The various models can be used in a wide range of applications, even under extreme conditions. SH type rotational speed sensors are used in a wide variety of applications in mechanical engineering, vehicles and mobile working machines, as well as in hydraulic drives.
The sensor detects the movement of ferromagnetic structures such as gears using the change in the magnetic flux. The sensor is biased using a permanent magnet. Teeth and gaps which moves past the sensor affect the magnetic field in different ways. This changes the Hall voltage on a hall-effect sensor.
This means the changes to the magnetic field can be converted to electrical values, and then filtered and processed. The output signal of the sensor is a square wave voltage which reflects the change in the magnetic field.

Close tolerance screen and stencil printing is usually associated with smaller-format substrates and print areas such as used in micro-electronics. In recent times, however, there is a growing need for larger-format applications as used in the medical, solar, display, and flexible electronic circuitry fields.
MTS® Series printers allow better process stability for large areas--in all axes, and with superior results based on your screen making capabilities. Preco’s X-Y-theta camera registration can be equipped with a variety of fiducial recognition techniques, to provide unique repeatable accuracy for all formats.

Function
Large board dimensions, different conveyor modes tor different throughput rates and a new high-speed inspection function - these
are the key product features of the X6. Printing tables with different designs tor different versions allow solder paste printing on partly assembled circuit boards (i.e. components mounted on the opposite side) with formats ot up to 610 x 550 mm. The choice
of the right circuit-board conveying system is determined by the required throughput rate. The single-track system conveys the
circuit-board safely through the printer and requires a handling time of only 12 seconds.
The single-conveyor HSP version with its tripartite conveyor belt shortens this handling time to less than 7 seconds.
The new high-end version of the EKRA 2 1/2-D postprint inspection delivers several images from up to 4 inspection stations every
second, thanks to the use of the latest linear engine drive technology. The use of a larger camera sensor increases the field
of view to 20 x 16 mm without any loss in resolution, ensuring that the 2 1/2-D postprint inspection system delivers consistently better results than the so-called line-scanner solutions and allowing
a thorough analysis of the solder paste printing quality on the basis ot its images.
Standard version with adjustable squeegee pressure and as a VIP head with weight compensation and fine-tuning for the squeegee
power. The automatic stencil-cleaning function also features in the basic version.

Siemens Automation und Drives presents the SIMATIC Mobile Panel 277F IWLAN the first wireless operator interface with integrated safety functionality.
When configuring the device, the user is supported by the WinCC flexible 2007 engineering software to define "effective ranges" in which the machine can be controlled by the operator.
A transponder limits the effective ranges in which the device can be identified locally. This ensures fail-safe operator control and clear assignment of the appropriate operating screens and operator authorizations anywhere in the plant.
The transponder can also be used to define zones in which certain functions are configured, such as automatic on-screen display or operator authorizations for particular persons when they enter the zone

Hydro-View
Monitor that displays moisture content readings from sensors
Located normally in a control panel, the Hydro-View unit is a simple to use moisture monitor that displays both the instantaneous and batch average moisture contents from a Hydronix sensor.
The unit which is available in both panel and wall mounting configurations may be used as a stand alone system for display purposes or with a batch controller to provide dynamic batch weight correction. A simple keypad arrangement on the front panel enables all operations to be easily configured and results viewed on the LCD display. Hydro-View is a multi-language system.
Trend Display
A unique facility of the Hydro-View monitor is the 'Trend Display' which will graphically chart the following four functions:
Raw sensor input voltage (V)
Sensor voltage after conditioning (Vc)
Instantaneous Moisture % (M)
Average Moisture % (A)
Although only one trace can be displayed at any one time, all four values are recorded simultaneously and any of the four traces may be selected. It is therefore possible to compare for example the raw sensor input voltage trace to the conditioned signal to assess the effectiveness of the signal conditioning parameters selected.

Western Research Model 241CE monitors the hydrocarbon dew point of pipeline quality natural gas. Hydrocarbon dew point monitoring is important to both pipeline operators and gas turbine operators since too high a dew point can cause operational difficulties and dramatically shorten equipment life. The Model 241 is a first principal device using a thermoelectric cooler to cool the gas to determine the dew point temperature.
