Description
The VEL-trol II is engineered to handle ultra-low differential pressure measurements with high accuracy. It features automatic zeroing to eliminate output signal drift caused by thermal, electronic, or mechanical effects, effectively making it a "self-calibrating" transmitter. The device provides dual transmitter output signals (4-20mA, 0-5VDC, or 0-10VDC) linear to pressure or flow and includes a multi-line LCD for configuration, calibration, and real-time process display. Its microprocessor-based functionality allows for electronic respanning, primary signal noise filtering, and high turndown ratio operation, making it suitable for demanding industrial environments.
Features:
- Automatic zeroing circuit for eliminating output signal drift.
- High accuracy at very low flows, maintaining an accuracy of 0.1% of Natural Span.
- Dual transmitter output signals configurable for 4-20mA, 0-5VDC, or 0-10VDC.
- Multi-line LCD for configuration and process display.
- Microprocessor-based functionality for parameter selection and signal scaling.
- Optional AUTO-purge management for "dirty air" applications.
- NEMA 1 aluminum enclosure for durability.
