EVO 1650

Terminal operators, field engineers, plant supervisors, inventory managers, and safety officers often require safe, ground-level access to tank gauge data, configuration settings, and calibration tools.

The evo 1650 Smart Core Display provides an intrinsically safe interface for interacting with Cognesense radar and servo tank gauging systems. It enables operators and technicians to access tank data, configure instrumentation, and perform diagnostics without climbing tanks or opening explosion-proof enclosures.

Unlike conventional remote indicators, the evo 1650 integrates directly with evo 1610 radar gauges and MCG servo gauges, providing local display a graphical LCD interface, infrared configuration using the MCG 2150 Remote Calibrator, broad protocol support, and diagnostic tools. This combination simplifies commissioning, calibration, and troubleshooting while improving safety and efficiency.

Designed as a microprocessor-based smart terminal, the evo 1650 supports RTD temperature inputs, 4–20 mA analog signals, discrete I/O, and Tankway, HART, Modbus, and RS-485 communications.

With a rugged NEMA 4X / IP65 enclosure and global hazardous-area certifications, the device delivers long-term reliability in refineries, storage terminals, chemical plants, and industrial tank farms.

How does the EVO 1650 improve worker safety?

−

The MCG 1650 drastically improves safety by enabling all gauge calibration and configuration to be performed using a wireless infrared remote from ground level. This eliminates the need for technicians to climb tanks or open explosion-proof housings, which are major safety risks in hazardous industrial environments.

Can the EVO 1650 be used with both radar and servo gauges?

+

Yes. The MCG 1650 Smart Core Display is designed for maximum compatibility and can interface directly with L&J’s entire evo Radar Series and MCG Servo Gauges. This universal compatibility reduces the number of spare parts and training required for your field personnel.

What communication protocols does the display support?

+

The display supports all common industrial protocols, including L&J Tankway, HART, and Modbus RS-485. This multi-protocol capability ensures that the data collected at the ground-level interface can be easily connected and communicated to your central DCS or inventory management system.

Is the EVO 1650 intrinsically safe for hazardous environments?

+

Yes. It has FM/CSA, ATEX, and IECEx certifications for operation in Class I, Div. 1 hazardous areas.

Can the EVO 1650 replace older field indicator displays?

+

Yes. Its protocol flexibility and analog/digital I/O allow drop-in modernization of older L&J or third-party systems.

Does the system support full calibration capabilities?

+

Yes. With the MCG 2150 calibrator, operators perform full configuration and calibration wirelessly without opening enclosures.

Is firmware upgradeable in the field?

+

Yes, Smart Flash enables firmware updates “on the fly” without removing power or disconnecting the device.

What parameters can be displayed on the interface?

+

Level, temperature, alarms, density (via paired gauge), discrete I/O status, and full diagnostic data depending on system configuration.
