Keller‘s OEM transmitters are systems that can be described as „embedded“ in the best sense of the word – and in two different ways. First, the sensor and the downstream electronics are embedded in the same housing and second, the transmitter capsules themselves are ideally suited for embedding in application-specific systems. Depending on requirements, the output signal is standardized and temperature-compensated (ratiometric or digital).

Significantly optimized solutions are obtained if close coordination between a component producer and a device manufacturer (to cite one such example) is initiated in a product’s development phase. Flexibility on both sides and – most important of all – digital signal processing yield benefits here: this is illustrated by the following example of a differential pressure measuring module that was developed in response to a customer’s request and which has now been integrated into a production flow controller.

AVIA Osterwalder St. Gallen AG operates more than 120 filling stations in eastern Switzerland. This company also sells and distributes motor vehicle and other fuels to corporate and private customers. For many years now, AVIA Osterwalder St. Gallen AG has deployed the EasyOil® system to offer its customers a practical method for remote monitoring of filling levels in oil and gasoline tanks. To assist with the recent relaunch of the EasyOil® system, AVIA Osterwalder St. Gallen AG called on the measurement technology expertise offered by KELLER AG für Druckmesstechnik.

Eilersen load cells tolerate up to 1.000% overload, which allows a very simple and hygienic mechanical installation.

The simple installation eliminates the need for maintenance and reduces the total cost of ownership

The Eilersen load cells feature excellent specifications, high reliability, simple installation and minimal maintenance for the use in tough and demanding industrial environments. Eilersen load cells are available with Profibus DP, DeviceNet, EtherNet/IP, EtherCAT, Modbus ASCII/RTU, RS485/422, RS232, 4-20mA and 0-10VDC interfaces, and can be supplied in OIML and ATEX certified versions.

The Eilersen load cells are produced in stainless steel and hermetically sealed (IP68/IP69K) by laser welding to ensure superb waterproof protection for tough industrial applications. Furthermore, Eilersen load cells are available in capacities up to 500t.

Avalanche Photodiodes for LIDAR Applications

To meet the growing market of laser based distance measurement, laser scanning and mapping, shape recognition and remote sensing, Avalanche Photodiodes (APD) especially suitable for LIDAR (Light Detection and Ranging) are needed. Preferentially, APDs are used for applications with very low optical signal strength or with high modulation frequencies, as it is the case with LIDAR.

The Rugged Computer RPC Compact 71 pushes the Embedded Specialist Syslogic into entirely new business spheres. This Rugged Computer is protected to category IP67; it has a fully enclosed housing, as well as the matching M12 plug connectors. The RPC Compact 71, in combination with its robust electronics, is almost indestructible.

Nowadays it is very important to use optimized processes to make a biogas plant profitable. The production of biogas is a strongly grown market in the last 20 years. In the beginning biogas was produced from manure to get rid of the “waste” in an intelligent way. Today biogas is a very important energy source that depends mainly on two factors -cost of substrate and effectivity of the gas production.

Antibodies and antibody fragments (ABF) are most important, highly demanded tools in diagnostic and therapeutic applications with predicted sales of 56 billion dollars by 2012
