Descrição

The OMB-TEMPSCAN-1100 is no longer available please see the OMB-DAQSCAN-2000 as a possible alternative or contact our data aquisition department.

The OMB-TEMPSCAN-1100 sets a new standard for speed, expansion and economy in data acquisition systems. The OMB-TEMPSCAN-1100 accepts any one of two scanning modules, for either thermocouple or RTD measurement. The thermocouple module accepts 32 inputs, while the RTD module
accepts 16 3-wire or 4-wire RTD sensors.

Expandable to 992 Inputs
With optional expansion chassis the OMB-TEMPSCAN-1100 can accept up to 992 inputs.
The OMB-EXP-10A two-slot chassis can accept one or two scanning modules. Multiple OMB-EXP-10A units may be daisy chained for expansions to the full input capacity. For systems with more than 96 inputs, the OMB-EXP-11A, 10-slot chassis provides more economical, convenient expansion.
Each OMB-EXP-11A provides up to 320 input channels in a compact and convenient enclosure.
Multiple OMB-EXP-11A chassis can be connected to one OMB-TEMPSCAN-1100 to provide a total system capacity of up 992 channels.

High Accuracy Measurement
The OMB-TEMPSCAN-1100’s multi-processor architecture provides linearized and compensated thermocouple-based temperature readings at speeds up to 960 channels per second, valuable in monitoring a large number of channels. The OMB-TEMPSCAN-1100 fast reading rate enables the unit to measure a sensor and activate an alarm much faster than alternative solutions. Also, a 16-bit A/D converter ensures measurement integrity. The A/D converter samples and averages multiple readings, resulting in high noise rejection from ac line pickup.

Internal Memory Storage for Logging Independent of a Computer
The OMB-TEMPSCAN-1100 is designed to facilitate datalogging at fixed-time intervals. The unit can be configured to begin and end logging on a user-specified event, such as a TTL input, temperature level, IEEE GET command, as well as time of day, or upon completion of a specified number of readings. An internal 256 k data buffer can be upgraded to 8 megabytes, ideal for both high-speed and long-term datalogging.

32 External Alarm Channels
Many process control applications require occasional temperature monitoring until a limit condition occurs. Once an alarm is detected, the system often needs to accelerate temperature measurement and simultaneously provide closed-loop control signals until the process returns to steady-state conditions. The OMB-TEMPSCAN-1100 provides 32 digital alarm outputs that actuate on user-specified alarm conditions, on a per channel basis. Once the limit condition is resolved, the alarm outputs return to steady state. OMB-TEMPSCAN-1100 can update alarmed output channels in real-time, at the max 960 channels per second rate. It can also be configured to alert the host computer of active alarm conditions via an IEEE-488 SRQ.

Multiple Triggering Options
The OMB-TEMPSCAN-1100 also provides separate pre-trigger and post-trigger scan intervals for quick reaction during alarm conditions. For example, the unit can be programmed to sample channels once per minute, and when a specified channel reaches a limit condition, to sample data once per second.

Sample Rates up to 960 Samples/Second
The OMB-TEMPSCAN-1100 scans groups of 16 consecutive channels during every ac line cycle (i.e., channels 1-16 scanned during the first line cycle, 17-32 during the second line cycle, etc.). This results in max measurement rates of 960 channels per second (at 60 Hz, 800 channels per second at 50 Hz). The OMB-TEMPSCAN-1100 IEEE-488 interface is well suited to laboratory applications that require real-time data transmission to the host for mass storage. Data transfer rates up to 300 kb per second are supported. The RS-232/422 interface supports baud rates from 300 to 9600, and can be used for process and environmental control.

RS232, RS422 and IEEE-488 Communications Standard
The RS-232/422 interface suits it for applications that require the placement of instrumentation at remote distances from the controlling computer, such as process and environmental control. The unit provides switch selectable baud rates from 300 to 9600.
Both its IEEE 488 and RS-232/422 interfaces support data retrieval in ASCII and, for high speed applications, in binary format.

No External Signal Conditioning Required
The OMB-TEMPSCAN-1100 is designed with convenience in mind. It requires no external signal conditioning, multiplexers, or custom cables saving the user both time and money. User-installable scanning modules provide all signal conditioning and amplification.

The scanning modules contain screw terminal sockets for quick and easy input connections. The modules slide into a metal, shielded enclosure within the OMB-TEMPSCAN-1100, keeping noise outside and maintaining a constant internal temperature. The OMB-TEMPSCAN-1100 and its expansion chassis accept three versions of scanning modules, allowing users to create systems of up to 992 channels. These scanning modules include:

Thermocouple Scanning Module:
OMB-TEMPTC-32B thermocouple scanning module contains 32 differential input channels, each of which may be configured for any thermocouple type or a millivolt input with ±100 mV range. Measurements may be returned in units of °C, °F, K, R, or mV.

RTD Scanning Module:
The OMB-TEMPRTD-16B scanning module supports 16 channels of 3- or 4-wire RTDs. Measurements may be returned in units of °C, °F, K, or R.

Remote/Modem Operation
The OMB-TEMPSCAN-1100 is for applications that require the placement of instrumentation at some distance from the controlling computer. The RS422 interface enables the OMB-TEMPSCAN-1100 to be located up to 1 Km from the computer. For greater distances, Chartview is is capable of controlling the OMB-TEMPSCAN 1100 via a Hayes compatible modem. To establish a modem link, a modem is required in the computer and an auto answer modem must be connected to the OMB-TEMPSCAN-1100.

CHARTVIEW SOFTWARE
The OMB-TEMPSCAN-1100 includes ChartView, Windows-based setup and acquisition application. ChartView provides a graphical spreadsheet style user interface that lets you easily configure your hardware, acquisition, and display parameters. ChartView features a no programming approach that enables data collection and display within minutes.
ChartView provides a number of data display options including a real-time smooth scrolling trend display, digital meters, analog meters, and bar graph meters. The collected data is stored to disk in an ASCII format so it may be easily imported into other applications, such as Microsoft Excel, for post acquisition display and analysis. In addition, ChartView also provides a real-time link to Excel using Dynamic Data Exchange (DDE). The OMB-TEMPSCAN-1100 also includes PostView, a post acquisition graphics display program that integrates seamlessly into ChartView. Using PostView’s intuitive on-screen controls, you can expand, contract and auto-scale waveforms as well as scroll in either direction. PostView also provides hardcopy printout of the waveform. The Standard ChartView is included with the OMB-TEMPSCAN-1100. An optional enhanced version of ChartView, ChartView Plus, is also available. The table to the right summarizes the differences between ChartView and ChartView Plus.
