High-resolution chart recorders

Click2Contact

A range of high-resolution paperless chart recorders, the VR series, is now available in Australia from CrispTech.

Available in two models, the VR6 offers up to six analog inputs and the VR18 handles up to 18. Unlike most chart recorders on the market, the VR series offers extremely high VGA screen resolution of 640 x 480 pixels, typically 4 times better than the standard 320 x 240 pixels. The colour LCD screen is also larger and more readable giving a huge 6.4" display.

The VR series is the most user-friendly way to monitor complex processes either directly on the screen or from a remote site using RS232, RS485, RS422 serial connections or via an ethernet network. It can be used to monitor, record and evaluate processes in plants such as chemical plant, wastewater, food and beverage, automotive, environmental monitoring, weather stations, laboratory or any plant processes. Historical data can be accessed online, recorded on a remote PC or stored locally on a Compact Flash Memory card.

A variety of customisation cards is available and these are common for both units. These include both analog and digital inputs and digital output relay cards, as well as an optional mathematics function. Both units come with a variety of AC and DC power options and all cards are interchangeable, thus providing a cost-effective upgrade path. Both units can be either panel mounted or desktop mounted.

The Observer 1 software package is included with each basic unit package and this allows local configuration and monitoring. The optional Observer II package provides remote network access and real-time data logging.
