High resolution chart recorder

Monday, 19 November, 2007 | Supplied by: CrispTech Pty Ltd


CrispTech has announced a range of paperless chart recorders, the VR series. Available in two models, the VR6 offers up to six analog inputs and the VR18 handles up to 18. The VR series offers extremely high VGA screen resolution of 640 x 480 pixels. The colour LCD screen is also larger and more readable, giving a 6.4" display.

The VR series allows the monitoring of complex processes either directly on the screen or from a remote site using RS232, RS485, RS422 serial connections or via an ethernet network. Historical data can be accessed online, recorded on a remote PC or stored locally on a Compact flash memory card with a capacity of 16, 64 or 128 MB.

A variety of customisation cards are 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 unit has six rear slots for easy expansion by plug-and-play I/O cards. These chart recorders have a guaranteed sample rate of 200 mS, even for 18 channels, because of an additional CPU on the analog input card, and boast high-accuracy 18 bit A/D analog inputs, and 15 bit D/A analog outputs.

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.
