Germany
720™ and 420 Plus DC weigh on-board
Oberhonnefeld, Germany — After eight years of selling and servicing weigh indicators for an American scale company in Germany, Heinz Gerd Schneider, salesman, and Horst Reinhard Pilz, service manager, made the decision to start their own business. They founded S+P Wägetechnik GmbH in 1990, selling and servicing weigh indicators, load cells, printers and remote displays to scale manufacturers and integrators. S+P Wägetechnik GmbH has been a Rice Lake distributor for weighing indicators in Germany since 2002.
Not too long after opening their doors, S+P Wägetechnik GmbH received a call from a customer looking for an on-board weighing system for a tip lorry. The impetus for the call was the increasing deposit charges for waste and garbage. With an on-board weighing system the driver has the ability to print a weigh ticket in the cab of the truck, eliminating the expense of driving to a scale and paying to be weighed in order to receive a weight ticket. The on-board weighing systems on the market at the time were approved as Class IV, which has a maximum number of verification scale intervals of 1,000. Heinz and Horst’s goal was to develop a more accurate on-board weighing system approved as Class III, with a maximum number of verification intervals up to 3,000.
 Most of these systems can be retro-fitted to vehicles. A printer is a standard component of every system, and Heinz and Horst know Rice Lake’s 720i HMI indicator can provide any function their customers require in the future.
They use the 420 Plus DC version for all applications without level compensation. The 420 Plus indicator provides the basic functions for the application and features a real-time clock; numeric tare entry; ticket print formatting; two serial I/O s for printer, computer or remote display; and digital I/O s for remote tare and print.
Rice Lake implemented custom software in the 520 indicator to compensate the weight according to the level. In applications with level compensation, a four-axis RS-232 sensor sends angle data.
All systems are OIML Class III approved by the Physikalisch-Technische Bundesanstalt (PTB), the national metrology institute in Germany.
Today, S+P Wägetechnik GmbH is the leading manufacturer of Legal-for-Trade on-board weighing systems in Germany and has customers in Belgium, France, Italy, Luxembourg, Netherlands, Austria and Switzerland. They offer a wide range of weighing systems using the 420 Plus, and 520 with special software that allows automatic level (tilt) compensation up to 6 degrees for each axis.
In the future, after getting OIML approval, S+P Wägetechnik GmbH will be using the new Rice Lake 720i DC indicator which has even more functions including multi-interval, alibi storage, programmability, databases, graphic display, external keyboard and more I/O s.
