The Sensoray Models
618/19 offer a cost-effective way to acquire sensor data for any PCI
bus system. They feature 16-bit resolution from 8 or 16 channels,
each individually programmable for a different sensor type. Analog-
to-digital conversion is performed in under 22 milliseconds,
providing 45 channels per second scan rate.
The 618/19 adapter boards plug directly into any PCI bus
computer. Linearization, calibration, and sensitivity are software
programmable, eliminat- ing trim potentiometers and the need for
board access. Sensor field wiring is accomplished with a
37-conductor flat cable and remotely mountable screw- termination
board, either model 7409TB or model 7409TDIN with DIN rail mounting
constant-voltage source is provided for strain and pressure sensors.
A pulsed constant-current source is provided for resistive sensors.
Lead loss errors from RTD's, thermistors, and resistors are
eliminated with the use of a four-wire circuit.
An on-board microprocessor continually scans the active sensor
channels. Each channel is amplified, digitized, filtered, converted
to engineering units, and stored in on-board memory. This process is
independent of host CPU activity.
The included SDK18 software has a
DLL for Windows 95/98/NT.
A ready-to-go data acquisition program, QuickSense, is
available as an
