Description

The Sensoray Model 118 Smart A/D offers a cost-effective way to acquire sensor data for any VME bus system. It features 16-bit resolution from eight input channels, each individually programmable for a different sensor type. Analog-to-digital conversion is performed in under 22 milliseconds, providing a 45 channel per second scan rate.

The 118 board plugs directly into a VME slot. Linearization, calibration, and sensitivity are software-programmable, eliminating trimpots and the need for board access. Sensor field wiring is accomplished with a 40-conductor flat cable and remotely mountable screw-termination board, either Model 7409TB or 7409TDIN with DIN mounting rail mounting hardware.

Calibration The 118 automatically self-calibrates by measuring internal references. Reference data is stored in an EEPROM so that boards may be easily interchanged.
Signal conditioning is provided for thermistors, RTD's, strain and pressure gauges, resistance and voltage. Standard corrections for non-linear sensors is built in. Custom compensation can be downloaded.

Excitation
A pulsed 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 four-wire circuits.

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 independent of the host CPU activity.

VME
The 118 board is available with 3U and 6U front panels. The board functions as a DTB slave (A16, D8) using two consecutive I/O ports.

Software
The included SDK18 software has a DLL for Windows 95/98/NT.

A ready-to-go data acquisition program, QuickSense, is available as an option.
