EasyFill is a software application for single-component dosing of liquids, powders and granulates with a user-specific configurable setpoint. The individual parameters such as tolerances or overrun corrections allow for simple filling. Filling control within the transmitter itself enables precise results to be achieved more quickly, as transmission times are eliminated.  The integrated digital inputs and outputs enable direct valve control. The control of the function is easy to integrate into control systems and the prefabricated dosing sequences enable an error-free process and reduce test runs and programming time.  

There are three flexible solutions for assigning the IP address: It is either defined manually by the operator, taken over by the assigned DHCP server or defined directly by the weight transmitter itself using the auto IP protocol (169.254.x.x). If the IP address is not known when automatically assigned, the devices are automatically displayed in the network environment or can be searched for using the Minebea Intec Indicator Browser included in the scope of delivery. 

The scale can be calibrated in several ways: 
1. the classic calibration with weights, in which the dead load and the calibration weights are weighed according to the specifications of the scale. 
2. the integrated "Smart Calibration" function enables efficient adjustment of the silo and hopper scale without the use of weights. For this purpose, the dead load value and the load cell characteristics can be entered directly. We record the individual load cell characteristics for each load cell in the production process on the calibration certificate. This precise knowledge of the load cell enables exact adjustment.  
If the dead load value is not known (e.g. has been read out from an old system), then a mixed form with weighing of the dead load and input of the load cell characteristics  
can be used.  The dead load values can be read out from all our transmitters for generations, which makes it easy to replace the electronics and transfer data when modernising systems. 

To obtain accurate weight values with the Link E weight transmitter, it is important to connect and adjust the load cell correctly. Make sure that the load cell is correctly mounted and aligned; our installation kits help you to align it correctly. It is also important to decouple the container; it should stand freely and pipelines, for example, should not form any force shunts. The selection of the correct load cell is also crucial for the exact weight value, the correct design, load introduction, linearity and load level are decisive (don't worry, we will be happy to advise you). 
Good cabling of the system should also not be forgotten, as the smallest signal to be transmitted is in the nano-volt range. The 6-conductor technology of the extension cable between the cable box and transmitter corrects the voltage losses by means of an additional sense line.  
Carry out these steps and the adjustment carefully and you will see how accurately the transmitter transmits the weight values to you.  

The word strain gauge measuring amplifier is often used as an alternative to the word weight transmitter. The term has its origins in the original function of converting/amplifying analogue load cell signals into standardised analogue current outputs, e.g. 4-20 mA. Nowadays, the analogue weighing signals are digitised and transmitted via various interfaces. In addition, they now also have software functionalities such as limit value switching or filling control, so we have decided to call them "weight transmitters".  
 

Yes, the analogue outputs can be configured to match the requirements of your specific application or to meet Namur 43 requirements.   
This allows for better integration into the process environment.  
For example, different ranges 0-20 or 4-20mA are available, but the transmission of the gross or net value can also be set. Different behaviour can also be defined, e.g. in the event of an error. 

Top-hat rail mounting offers a space-saving and practical way of installing the Link E weight transmitter in a control cabinet or housing. Like all other process components, the slim plastic housing fits neatly on the top-hat rail. This facilitates integration into industrial environments and ensures neat and quick installation. They can be mounted on the top-hat rail without tools, they are simply "clicked in". 

The PR5230 weight transmitter has 3 relay outputs (1A) that can switch valves directly on site. When using the integrated limit function, limit values can be defined and the corresponding relay outputs switched, making it possible to refill containers, for example. The PR5230 has a large number of cable glands so that everything can be connected with IP65 protection.   

The linearity of a scale is decisive for the accuracy of the weight measurements. On the one hand, this is about the linearity of the electronics, which show the same behaviour under different temperature influences, for example, and on the other hand about the load cells and the scale construction, which react mechanically linear to different weight values. Good linearity is achieved when the gradient of the weight curve is more of a straight line than a curve and reacts in the same way when loaded and unloaded.

The weighing range of the Link E weight transmitter depends on the connected load cells.  
The basic data of the scale are defined during calibration, i.e. the maximum weight value, the readability/resolution, the decimal places and, with the measuring rate to be set, also the speed of weight generation. This can be adjusted using filter settings, e.g. for unstable environments.

The transmitters can display the weight value in different units. This is also determined during calibration. Conversion to the classic kg, g, t are the most common applications.  

The required supply voltage is 24 VDC. This is the standardised voltage that is often used in control cabinets. If you have a 230 V application, the PR 5230 transmitter or the X3 weighing indicator for control cabinet installation is a good option. 

The measuring rate of the Link E weight transmitter determines how quickly the device records and updates weight values. A higher measuring rate can improve readability and weighing performance, especially in applications where rapid weight changes need to be recorded. The choice of the correct measuring rate depends on the specific requirements of your application.

Some of the transmitters can be configured directly in the browser or using a remote operating tool "VNC" via the network interface. VNC enables the operation of a "virtual" device, but can also be used to realise a PC-based secondary display or an operating terminal. This tool can also be installed on mobile tablets, making operation a completely new user experience. All transmitters have an integrated web server that enables extended service functions, diagnostic aids or software updates. Depending on the network access, the network interface can of course also be used remotely.
