Miniature Process Loop Data Logger

The company offers a miniature data logger designed for convenient in-field recording of 4-20mA process loop signals. A self-powered, stand-alone unit with its own internal memory, the Spectrum 4000-25C Precision Current Loop Data Logger offers a simpler and lower-cost alternative to traditional chart recorders and full-featured data acquisition systems.

Palm-sized and equipped with a dual function 4-20mA/5Vdc input channel, the unit is designed for easy installation and setup for continuous long-term recording and monitoring of process loops. The unit requires no power connection and offers inherent circuit isolation.

Designed for reliable long-term operation in harsh industrial and field applications, the Spectrum 4000-25C is rated for use from –40 to 70°C (-40 to 160°F). Equipped with 12 bit resolution, the unit offers a full scale accuracy of 0.15% and can monitor minute variations in loop current with an average precision of 5.5 microamps (0.025% F.S.). The logger features a high degree of immunity from electrical interference and physical shock and vibration. Non-volatile EEPROM memory ensures long-term data protection in the event of damage to the unit.

It provides a convenient and accurate means to diagnose, verify and document the performance of systems, equipment, and processes. It can be used as a component of an integrated measuring system of for field applications requiring portability and battery operation.

The Spectrum 4000-25C works with Spectrum Software, a Windows 95, 98 and NT-compatible program that creates automatically-scaled graphs, charts, and printouts. Users can display data logger readings directly in milliamps (mA) or scale to user-selectable engineering units. Users can also export text files for use in other Windows spreadsheet, database or word processing programs.
