Environmental Analysis New Range Makes Data Logging so Simple
Grant Instruments (UK), a world-renowned supplier of data acquisition products, has introduced its Yoyolog range of mini data loggers to provide a robust, versatile and low cost solution for measuring and recording physical and electrical parameters across a wide range of industrial, scientific, environmental and agricultural applications.
The new ergonomically designed, battery operated range of data loggers measure just 50mm in diameter and are similar in size and shape to a toy called the Yoyo, hence the name. The loggers are simple to set up and quick to deploy and measure temperature, humidity, condensation, extra low voltage, strain gauge, voltage and current, pulse, barometric pressure, light and radiation.
Due to their small size, being shockproof, and featuring a water and dust resistant IP65 enclosure, the Yoyolog loggers can be placed almost anywhere, inside or outside. For example, the Yoyolog light data logger (YL-M61) which records luminance with a spectral sensitivity adjusted to the spectrum of the human eye, is suited for operation indoors or outdoors.
The Yoyolog range includes 19 different models which come in different designs and enclosures to meet specific application needs. For example, some models have integrated sensors, particularly useful for monitoring shipments. Other models feature connectable probes for differentiated analyses with various parameters, and then others have a sensor integrated in a 100mm stainless steel tube, which is ideal for measurements in air ducts or for pharmaceutical or biological research.
Nathan Neal, sales and marketing director of Grant Instruments, said: “Our Yoyolog range has been developed in response to customers who want a small, low cost, easy-to-use, application specific logging solution that is reliable, robust and durable. We believe that the new design and the multitude of configurations, plus our software, support and reputation for high quality, will make the Yoyolog range a popular choice in many fields including agriculture, laboratory and healthcare, building monitoring, meteorological research, clean rooms, food processing, logistics and environmental studies.”
Unusually for such a small device, the Yoyolog loggers feature a high resolution 20-bit analogue to digital (A/D) converter, giving the accuracy normally only expected from significantly more expensive units. They can store up to 4 million readings, include a Lithium battery (which last up to four years) and are supplied with YoyoView configuration and data download software, a USB cable and manual. The Yoyolog range also includes a wide range of optional accessories including sensors and probes, a wall holder, lead seal kit, rain gauge and radiation protector. All models come with a 2-year warranty.
A brochure featuring full details and the technical specifications for the new Yoyolog logger range can be downloaded from their website.
The Yoyolog range of mini data loggers complements Grant Instruments’ established Squirrel range of high specification, portable data logging systems and the dataTaker range of rugged, fully integrated custom- configurable acquisition and control systems.

New Guided Wave Radar from VEGA
The new VEGAFLEX 80 Guided Wave Radar from Vega Controls (UK), ‘automatically’ delivers versatility and reliability for level and interface measurement in both liquids and solids. This technology is already known for its unerring performance under changing conditions, such as temperature, gases, vapours, density and pressure.
Many functions that commonly need manual adjustment with GWR devices are now automated with VEGAFLEX 80, thus improving life-time functionality. For example; on hydrocarbons and liquid gases, automatic systems ensure the low reflectivity level signal is monitored, whilst ignoring any highly reflective water condensate build up beneath. Automated empty vessel mapping ensures on going build up is detected and ignored. For changing product properties and saturated steam, it employs auto-compensation to maintain accuracy. Other systems include; automated overfill protection, dynamic echo tracking, dielectric/moisture content monitoring and probe length/condition detection. These are particularly designed to remove labour-intensive interventions after start up, to maximise safety, increase productivity and reduce costs.
Devices are supplied ready calibrated with an optional automated set up wizard, for optimising sensors to level, interface and dielectric measurement. A wide choice of output protocols and asset management capabilities include; twin analogue outputs for interface and top level, HART, Profibus, FF and Modbus. EDD and FDT/DTM set up capability are available as standard.
Series 80 has upgraded sealing, hygienic designs, temperature and pressure ranges. The certification and qualification portfolio includes; ATEX, Marine, FDA, EHEDG, SIL 2/3, NE107 and EN for 72hr boiler control. All of these product improvements equip VEGAFLEX 80 for excellent operational performance, process compatibility and investment return.
