Download New Rate Totaliser Application Guide
T
his new application guide from BEKA associates is intended to aid the selection of the most suitable pulse input rate totaliser from the extensive range of models manufactured by BEKA in the UK. It contains a brief review of pulse output flowmeters and the associated terminology, including an explanation of what the number of flowmeter output pulses and their frequency mean. All BEKA pulse input rate totalisers have similar functions and a common configuration menu enabling them to calculate and display total flow and the rate of flow in engineering units. This application guide takes the reader step-by-step through the simple rate totaliser configuration routine, including practical application examples. BEKA pulse input rate totalisers include single and two input models for field and panel mounting. In addition to general purpose instruments, internationally certified intrinsically safe Ex ia and Ex nA instruments allow installation in gas and dust hazardous areas. Display backlights, alarm outputs, isolated pulse and 4-20mA outputs for retransmission are available as factory fitted options further extending the applications for these instruments. BEKA also manufacture loop powered 4- 20mA Rate Totalisers.

Kistler presents new LabAmp 5167A
istler enlarges its portfolio of laboratory charge amplifiers with the new LabAmp 5167A, which allows for quasi-static charge measurements and adds new
features to the LabAmp family. A special version with Fischer-connector is available that is waterproof and compatible with all new stationary force dynamometers for metal cutting applications. Providing users with more flexibility, the amplifiers are able to quickly and easily acquire digitized data from actual measuring signals without complicated additional equipment. The product portfolio is completed by a new Version of the DynoWare software for easy to handle data acquisition and analysis. In order to receive usable measurement results, the underlying sensor signals
must be conditioned and processed accurately and low-noised. Here, Kistler offers an attractive portfolio of solutions for signal conditioning and subsequent data digitization. Piezoelectric sensors with a charge output (PE sensors) operate reliably with charge amplifiers.

Maintenance-Free Maestro ULTRA Piston Pump Can Increase Test Accuracy and Instrument Reliability
They can be used as a part of the wash cycle that cleans the machine between samples or as buffer solutions to reduce the risk of sample cross-contamination. Salt solutions help to ensure your machine provides accurate and reliable test results.

However, these vital solutions are hard on an instrument’s fluidics systems, and they are especially challenging for dispense pumps. Throughout the lifetime of a pump, salt builds up on the pump’s piston. This slowly erodes the seal until a catastrophic leak occurs. Your customer’s testing is halted until service technicians come and replace the pump.
The common industry solution to this problem is flushed seal pumps. Flushed seal pumps add a secondary fluid chamber and seal to the pump to keep salt from drying on the piston. However this design introduces many challenges and risks for instrument manufacturers. A second pump system is required to circulate the wash fluid, and the pump dimensions must increase to make room for the secondary fluid chamber. This system also makes leaks harder to detect – a leak of the main seal would lead to sample contamination by the wash fluid rather than pump failure. Cross-contamination risks increase exponentially when flushed seal pumps are strung together in parallel, endangering the reliability and accuracy of test results.
BioChem created a unique piston pump to solve these problems.
The Maestro ULTRA piston pump eliminates the need for maintenance in instruments and applications using salt solutions. Like our original Maestro Piston Pump, machined critical components allow for tighter tolerance control, resulting in improved accuracy, precision, and pump life. The ULTRA has been engineered to last in salty environments, featuring a new, super-hydrophobic piston material which keeps fluid and salt from adhering to the piston. The accuracy and precision our Maestro line of piston pumps helps to ensure your instrument provides the most accurate test results. With Maestro ULTRA your instrument can withstand your customers’ harshest solutions so they experience less down time due to maintenance and spend more time saving lives. ULTRA is truly the pump that conquers salt. Find out more about the Maestro ULTRA by visiting
