Description

Series 6800 ready-to-run, high performance Thermocouple Measurement Systems are available in many configurations. Each 6800 is equipped with an amplifier, filter and digitizer plus a Uniform Temperature Reference (UTR). Systems interface to a familiar Windows based operator workstation over USB 2.0 where the included software, PI660, is used for setup, display and acquisition of thermocouple data. Each channel has a differential +/- 10V input and can digitize and record data to 16-bit resolution. Digitization rates up to 2,000 samples per second per channel are provided. Additionally, individual channels have an upper and lower programmable alarm capability that is checked each time the output is digitized. Solutions are available for providing digital outputs based on these alarm conditions. PI660 allows for acquisition and control of one or many 6800 systems and provides real time display of thermocouple data. Data can be displayed and recorded in any number of ways, creating a versatile system that can fit any application. Series 6800 is fully compatible with Pacific Instruments’ Series 6000 Transducer Data Acquisition Systems.

PI660 Turnkey Software

PI660 software is the choice for test management, data acquisition, and data display. PI660 controls the Pacific Instruments Series 6800 Data Acquisition System. It provides all the tools for test definition, test setup and tracking, transducer calibration, data acquisition and display, data replay, data export, and test quality validation. PI660 is turnkey, intuitive and easy to use. The ribbon style control panel provides logical access to the various steps of programming. The software even supports a password protected user account mode where functionality can be turned on or off based on the needs of the facility. Learn more about PI660 Turnkey Software.
