All of this dramatically improves revenue collection and cash flow compared to current standard transfer spec- ification meters that are limited to manually recorded prepayment functions residing on the meter. Powering a bright future The Nigerian government’s Power Sector Recovery Program (PSRP) has already made strides in imple-

crucial, as it ensures accurate power consump- tion data is sent directly to a power utility via a network of application servers, enabling immedi- ate supply and payment. In fact, advanced metering infrastructure has evolved far beyond simple smart meter technol- ogy. It is a reliable, secure and cost-effective al- ternative to a standard smart metering solution

menting power sector reform, reducing losses in DisCos, enhanc- ing the sector’s financial viability, increasing access to electricity services, and mobilising private sector investment. For the PSRP to succeed, government and independent power producers should work collaboratively with tried and trusted suppli- ers with proven global experience and expertise across the entire value chain, including power generation, transmission, distribution and automation. Never before in Nigeria’s history has it had such great access to the technology and expertise to build a modern state on the back of modernised electrification infrastructure. This is a perfect storm of opportunity.

that requires a large amount of capital expenditure for procurement, installation and management. It also delivers peace-of-mind that

the deployment will always be available, reliable, highly responsive, and fully secure for mission-critical meter-to- cash process. Advanced me- tering infrastructure drives immediate business case re- turn-on-investment with de- creased deployment times, no resource ramp up require- ment, and no large capital ex- pense of an onsite solution. It delivers a revenue se- curity solution by simplifying budgeting with a predictable monthly per meter cost.

Robust speed sensors with ATEX and IO-link The new speed sensors are the compact solution for speed monitoring because the evaluation electronics are integrated in the sensor hous- ing. The limit at the speed of which the output switches is set via a potentiometer or IO-Link. IO-Link provides additional functions such as remote information about the current speed or the switch point and the configuration of important additional parameters such as the start- up delay time. IO-Link allows direct communication with the controller. The integrated sensor is damped by passing cams or other metallic targets. The evaluation unit determines the period duration or the fre- quency (actual rotational speed value) on the basis of the time interval between damping and compares it to the set switch point (preset value). The output is switched during the start-up delay and when the rotational speed exceeds the set switching value. An LED signals un- derspeed and switch-off of the output. Both rotary and linear move- ments can be monitored for overspeed, underspeed and blockage. As compared to its predecessors, these new sensors feature a robust metal housing

Time of flight technology as standard sensor The O5D with time of flight technol- ogy (PMD = Photonic Mixer Device) combines the following advantages: long range, reliable background sup- pression, visible laser light and high excess gain. In the same price range as standard sensors, it is a clever al- ternative. The switch point is set easily to the nearest centimetre via ‘+/-‘ buttons and display or alternatively via IO-Link, allowing read-out of the actual value.

Polished, matt, dark or light objects of any colour: the O5D features reliable background suppression. The unit allows any angle of incidence and thus flexibility of mounting. This simpli- fies installation and saves costs. Some applications for these sensors include detection on a conveyor belt in the confectionery industry, identification and detection of interchangeable tools and the loading condition of conveyor belts.
