CONTROL SYSTEMS + AUTOMATION

Environmental management and control withThermo-Hygrometer Fluke and HART Scientific have revolutionised environmental monitoring for calibration labs with their model 1620A DewK which offers Ethernet and wireless connections and upgraded LogWare III software. that the DewK canmonitor two locations simultaneously. Both sensors can be run via extension cables to remote locations up to 100 feet away, or one sensor can be directly mounted to the top of the DewK. Each sensor is calibrated for both temperature and humidity at Fluke Calibration.

Accuracy: Two types of sensors are available from Hart (represented locally by the Comtest Group). The high-accuracy sensor (‘H’ model) reads temperature to ± 0,125°C over a cali- brated range of 16°C to 24°C. Relative humidity readings are to ± 1,5% RH from 20%RH to 70%RH. The standard-accuracy sensor (‘S’ model) reads temperature to ± 0,25°C over its calibrated range of 15°C to 35°C. Relative humidity readings are to ± 2% RH from 20% RH to 70% RH. All DewK sensors come with NVLAP accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability. Ethernet and wireless capability: The DewK features built- in Ethernet RJ45 jack and multiple DewKs can be monitored from the same screen using the new LogWare III client-server software. Ethernet also allows for the possibility for remote connectivity over the internet. Maths and statistical functions: In addition to temperature and humidity, the DewK calculates dew point, heat index, and rates of change for both temperature and humidity. Min, max, and a variety of other statistics are also calculated and can be shown on-screen. Calibrated sensors: The DewK has inputs for two sensors, each measuring both temperature and relative humidity, so Vertiv , the business formerly known as Emerson Network Power, has officially launched under its new branding in South Africa. Vertiv is a global provider of mission-critical infrastructure technologies for vital applications in data centres, communication networks, and commercial and in- dustrial environments.The company, which is headquartered in Columbus, Ohio (USA), has more than 20 000 employees and 28 manufacturing and assembly facilities worldwide. Vertiv will continue to build on the broad portfolio of product and service offerings for power, thermal and IT management capabilities it previously offered as Emerson Network Power,

Memory: The DewK has an impressive memory capacity – enough to store up to 400 000 date- and time-stamped data points (i.e. two years’ worth of data for both measurements from two sensors from readings taken at tenminute intervals). Alarms and battery back-up: Alarm settings are eas- ily made based on temperature, the rate of change in tem- perature, RH, the rate of change in RH, and instrument fault conditions.

Rebranding – new name, same capabilities

including its industry-leading flagship brandsASCO, Chloride, Liebert, NetSure andTrellis. Backed by over 255 service centres worldwide, with over 3 000 service field engineers and more than 400 technical support/response people, Vertiv is able to support customers wherever they are across the globe. “We have been in SouthAfrica for many years and asVertiv we will continue to support the country’s evolving needs in IT and digital infrastructure” added Pierre Havenga, managing director of Vertiv in the Middle East and Africa. “We thrive towards ensuring our technologies fulfill local customer re- quirements to optimise their operations with the highest levels

of availability and reliability in all market segments, from the public sector to healthcare to finance. At the same time, we are looking at reinforcing our partnerships and growing the local network of technology distributors and resellers. “South Africa is a key country for Vertiv as it serves as the hub through which products, pre- sales and after sales services flow for the entire sub-Sahara Africa region, and through which all South and East Africa transactions are processed, including the SouthAfrican Development Commu- nity (SADC) for a total of 25 countries,” continues Pierre.
