The OMB-TEMPBOOK-66 data acquisition system adds voltage and thermocouple measurement capability to notebook PCs for portable test applications and also provides an effective alternative to plug-in boards for desktop PCs. The OMB-TEMPBOOK-66 provides
12-bit, 100 kHz data acquisition and data transfer to a PC via an enhanced parallel port (EPP) interface or PCMCIA link. The unit can also connect to a standard PC parallel port and can transfer readings directly to disk at 30K to 50K samples per second depending on the computer. An external module with the same footprint as a typical notebook PC, the OMB-TEMPBOOK-66 can be attached directly under a notebook PC for portability.
ABOUT THERMOCOUPLE ACCURACY
The accuracy of a thermocouple measurement depends on a number of factors, including thermocouple accuracy, cold junction sensor accuracy, A/D conversion measurement accuracy, and linearization accuracy.
The OMB-TEMPBOOK-66 employs accurate components and software compensation techniques to minimize or eliminate error from these sources. For example, an OMB-TEMPBOOK-66 system provides ±1°C cold-junction sensor accuracy, which directly contributes to the accuracy of the overall thermocouple measurement.
When the OMB-TEMPBOOK-66 is software calibrated, its gain and offset errors are virtually eliminated and are removed from subsequent readings as an error source. In addition, the OMB-TEMPBOOK-66's built-in auto-zero channel dynamically eliminates any other system offset errors.
In short, the OMB-TEMPBOOK-66 ensures accurate thermocouple measurements by giving you the ability to eliminate nearly all sources of error.
THERMOCOUPLE AND VOLTAGE INPUTS
The OMB-TEMPBOOK-66 has a built-in analog capability that permits it to measure eight channels in differential input mode or
16 channels in single-ended mode. Its on-board programmable gain instrumentation amplifier can be set to gains of x1, 2, 5, 10, 20, 50,
100, or 200 on a per-channel basis. Its A/D converter scans selected channels at a constant 10 µsec/channel rate, minimizing the time skew between consecutive channels. The time between the start of each scan sequence can be programmed to start immediately or at intervals of up to 10 hours.
FLEXIBLE TRIGGERING
The OMB-TEMPBOOK-66 features
a hardware-based digital/TTL
trigger that minimizes trigger
latency to less than 10 µsec. The
OMB-TEMP-BOOK-66 can also be triggered from a command from
the PC.
GENERAL PURPOSE DIGITAL I/O
The OMB-TEMPBOOK-66 includes 8 general-purpose digital inputs and 8 general-purpose digital outputs. These TTL-level digital I/O lines can be accessed by the PC whenever OMB TEMPBOOK-66 is not transferring data from the A/D converter. If an application needs to read digital inputs concurrent with analog inputs, the 8 digital inputs can be read within the scan group as high-speed digital inputs.
SCREW TERMINAL CARD
The removable screw terminal
card also accommodates easy
and secure input connections and enables a single
OMB-TEMPBOOK-66 to be used in multiple applications, by permitting the user to disengage the unit without disturbing any of the connections.
POWER
The OMB-TEMPBOOK-66 can be powered by the included ac adapter, a standard 12 V car battery, any
+9 to 20 Vdc source, or an optional rechargeable nickel cadmium battery module (OMB-DBK30A). This makes it ideal for field and remote data acquisition applications.
SOFTWARE
The OMB-TEMPBOOK-66 is supplied with TempView, a Windows-based datalogging application that allows you to set up your acquisition application and save acquired data directly to disk. The package also includes thermocouple linearization for direct readout of temperatures. The
OMB-TEMPBOOK-66 is also shipped with PostView, a Windows-based post-acquisition waveform display application that permits you to display acquired data previously saved to a file.
In addition, the OMB-TEMPBOOK-66 includes DOS drivers for Quick Basic, C, and Pascal; Windows drivers for Visual Basic and C for Windows; and VBXs (Visual Basic extensions). Several graphical analysis and control software packages also support the
OMB-TEMPBOOK-66.
RECHARGEABLE BATTERY MODULE
The optional OMB-DBK30A rechargeable nickel-cadmium battery module facilitates the
OMB-TEMPBOOK-66's use in portable applications. Housed in a metal enclosure of the same size as the OMB-TEMPBOOK-66, the module includes industrial-strength Velcro-style tabs for easy attachment under the
OMB-TEMPBOOK-66. The
OMB-DBK30A's battery life is
6 hours and the unit can be recharged via the included ac adapter.
PCMCIA INTERFACE CARD
The OMB-DBK35 PCMCIA interface card enables you to connect the OMB-TEMPBOOK-66 to your notebook PC's Type II (5 mm) PCMCIA card socket. It transfers data at up to 800 kbytes/sec. The interface card is PC Card 2.1 compliant.
