EX1000 Series

Product catalog summary

Overview
The EX1000 Series by VTI Instruments is a high-density, compact data acquisition system designed for precision and reliability. It features LXI™ LAN connectivity, integrated signal conditioning, and supports various transducer types such as thermocouples, voltages, RTDs, thermistors, frequency, strain, and pressure. The series is scalable, allowing expansion from tens to thousands of channels, and includes a DC version for proximity to test articles. Self-calibration and web-based access enhance usability.

Specifications
The EX1000 Series supports a wide range of transducer types with independent signal conditioning paths and software-selectable filters. It offers end-to-end self-calibration for each signal path, ensuring accuracy despite drift or temperature variations. The instruments are scalable for synchronized high-speed, high-channel count applications and feature open transducer detection for channel status monitoring.

Signal Conditioning and Protection
The EX10SC modular platform extends the EX1000's capabilities, supporting various transducer types on a per-channel basis. It provides exceptional input protection and isolation, suitable for environments with high electrical noise or transient power surges. Supported inputs include thermocouples, RTDs, thermistors, potentiometers, strain gages, pressure, high-level voltage, frequency, and current.

Installation and Control
The EX1000 Series is fully LXI™ compliant, facilitating distributed measurements and reducing cabling costs. It connects directly to LAN networks and features a web-accessible user interface for easy setup and control. The EXlab software provides a programming-free setup, data logging, and measurement display.

Environmental Specifications
The instruments operate within a temperature range of -5°C to +55°C for AC models and -10°C to +65°C for DC models, with storage temperatures from -40°C to +70°C. They conform to MIL-PRF-28800F standards for shock and vibration, supporting operation up to 3000 meters in altitude.

Model Selection
The series includes models like EX1000A, EX1000A-TC, EX1016A, EX1032A, and EX1048A, each with varying channel capacities and input types. The EX10SC module offers additional signal conditioning capabilities with 16-channel capacity and 1500Vrms isolation.
