Web data logger stores variables accurately

THE monitoring of measurements of illuminance, temperature, atmospheric pressure, humidity and CO2 is critical in the manufacture and storage of electronics, pharmaceuticals and frozen foods and other temperature sensitive applications.

The ongoing tightening of regulations in this regard is making South African industry take a new look at how accurately their processes are monitored.

Against this background and to ensure that temperature spikes outside of accepted parameters are recorded and acted upon immediately, Delta OHM, part of the GHM Group, is offering their HD50 Web Data Logger.

The HD50 is a measuring device that stores data in a memory that can be located locally (in the instrument) in a database (on a pc or server) or in the cloud. The HD50 was developed for usage with one logger, which can be extended to an unlimited network of loggers.

Settings can be opened from a web browser, as it has a built-in webserver. This way it is also possible to monitor the actual measurements. Delta OHM already has the HD35 series, based on RF communication. In some cases when networks are very wide or complex or divided into more than one building, a mix of cabled, WiFi and Radio Frequency loggers can be the best solution. It’s possible to integrate the HD50 series into such hybrid networks.

“Apart from easy to use web browser access and its ability to be applied as a stand-alone or linked to numerous networks with hundreds of loggers, the HD50 can support practically ‘any signal’. Universal inputs make it possible to integrate any transmitter with standard output,” said Jan Grobler, Managing Director of GHM Messtechnik South Africa.

“Additional software is available for all solutions: database locally on PC, database on local server or cloud based. We also offer optional software for CFR21part11 utilised in the pharmaceutical market.

“The HD50 has a wide range of standard sensors (°C/ RH / LUX / Atm / CO2) and the logger sends an email alarm when a value is higher or lower than the set threshold” Grobler said.
