Test & measurement Never be lefT iN The dark
With the ever growing demand for LED lighting systems, Martindale Electric has now made it quick and easy to verify the performance of new LED installations with the LM195, a high quality light meter with built in correction factors for LED light sources. The LM195 delivers fast, reliable readings for a wide range of LED, fluorescent and incandescent lighting, ideal for ensuring regulatory compliance and adequate performance of new and existing lighting systems in industrial and commercial environments. Designed for use with the very latest LED lighting systems, the LM195
provides accurate readings up to 200,000 lux with a maximum resolution of 0.1 lux in the 200 lux range. The sensor can be rotated to cater for oblique angles of lighting and detached completely for easy access to any source. Suitable for both the commissioning of new installations and checking
the performance of existing lighting installations, the new LM195 can be used to ensure correct lighting levels which meet the required levels for a safe and healthy working environment. Also available from the latest range of light meters from Martindale
Electric is the new LM192 light meter. Suitable for use on different types of lighting with manual compensation, the LM192 is a general purpose light meter which can be used to achieve optimum results through the high performance detachable sensor. Able to operate for approximately 80 hours on one set of batteries, both
new models feature an intuitive layout and include Min/Max and Hold functions. Encased in rugged housing, both the LM192 and LM195 from Martindale Electric are supplied with alkaline batteries, carry case and Martindale’s
comprehensive two year guarantee.

New TachomeTer applicaTioN Guide
BEKA associates has recently published a new Application Guide AG314 describing its extensive range of tachometers for use in safe and hazardous areas. The guide includes comparison tables to aid selection of the most suitable panel or field mounting model, plus a detailed description of how the instruments function. The guide also explains instrument configuration and includes practical configuration examples. This range of tachometers can operate with most common types of sensor including proximity detectors, voltage pulses and magnetic pick-offs. Configuration is simple and will be familiar to many users as it employs the same basic menu and terminology as all other BEKA instruments. In addition to the general purpose models, Application Guide
AG314 describes the internationally certified intrinsically safe Ex ia models which enable speed measurements to be made in all gas and dust hazardous areas. For lower risk applications in Zone 2, the Ex nA certified models which can be installed without the need for a Zener barrier or a galvanic isolator are also included. The guide concludes with a description of tachometer accessories including display backlights, alarm outputs, plus isolated pulse and 4/20mA
outputs for retransmission applications.

PULS Power believes that system availability, cost efficiency and scheduled maintenance are the key criteria for most industrial and building automation system designers and installers. During the system design process PULS works closely with its
customers to provide detailed advice on selecting the optimum power supply for their specific applications. To enhance this service, PULS has developed the unique SmartFab Box. The SmartFab Box is an innovative diagnostics tool, which makes the
power requirements and thermal conditions in systems and installations transparent. It allows users to check and specify their power budgets directly on their own systems, live and completely securely. The SmartFab Box is available to PULS customers free of charge for a
limited period of time or it may be leased for longer term analysis of the effects of changes or improvements to power systems. This unique user service provides assistance in selecting the right power supply and avoiding over specifying excessively large power reserves. Customers can analyse an application’s data live at any time via the online
dashboard. For answers to questions or recommendations on the results, the PULS application engineering team is always ready and willing to offer support. The SmartFab Box measures voltage and current (input and
output), power (primary and secondary), transients, power factor and temperature (ambient and inside enclosure). Installation and operation of the SmartFab Box is simple. All that
is required is an AC mains connection and an LTE / 3G cell signal. The sensors of the SmartFab Box are then connected to the application and the setup is ready to start the analysis.
20 The non-invasive
measurements use a VPN connection to the SmartFab Box saving all application data securely and anonymously to a cloud server in Germany. The data is exchanged over the LTE / 3G cellular network and there is no requirement to connect the SmartFab Box to the local corporate network. The SmartFab Box is designed to be non- invasive at all times and will not affect the application during the installation or when taking measurements. This assures absolute safety and integrity of the customer's process. The web-based user interface, which provides live analysis of
measurement data, can be displayed on a PC or notebook and is very intuitive and simple to use. The operator can access data via the online dashboard. The dashboard is password-protected and accessible only to authorised users and a qualified PULS support team. Typical applications for PULS DIN-Rail power supplies include,
industrial and process control, building automation, panel-building, test and measurement, instrumentation and communications systems. Versions are available approved for railway systems and ruggedised for harsh environments.
