OM-EL-USB-TC-LCD-Logger

Supported Applications

The OM-EL-USB-TC-LCD is a standalone thermocouple data logger that measures and stores temperature readings from Type J, K, or T thermocouples. Because it accepts external thermocouples through a female subminiature thermocouple connector, it can be paired with a probe suited to the target environment, extending its reach far beyond the range of self-contained sensor loggers.

Typical applications include:

• Furnace, oven, and kiln temperature profiling.
• Process, plant, and equipment temperature monitoring.
• Refrigeration, freezer, and cold-chain verification.
• Laboratory and research temperature studies.

The logger plugs directly into a PC's USB port with no USB cable required, and its high-contrast LCD lets technicians read the current temperature on the unit. A free Type K insulated beaded wire thermocouple with subminiature connector (Model No. SC-GG-K-30-36) is included so the logger is ready to deploy on arrival.

Operating Conditions & Performance

The data logger module is rated for an operating temperature range of -10 to 40°C (14 to 104°F). This applies to the module only; the temperature that can be measured depends on the attached thermocouple, which supports the following ranges:

• Type K: -200 to 1350°C (-328 to 2462°F).
• Type J: -200 to 1190°C (-328 to 2174°F).
• Type T: -200 to 390°C (-328 to 734°F).

Measurement performance is defined by a resolution of 0.5°C (1°F) and an accuracy of ±1.0°C (±2.0°F). This quoted accuracy is for the data logger only and excludes the thermocouple probe, so probe error should also be taken into consideration.

The logger stores up to 32,510 readings, with the logging interval selectable in software as 1 sec, 10 sec, 1 min, 5 min, 30 min, 1 hr, 6 hr, or 12 hr. Temperature units, thermocouple type, alarm thresholds, and start date/time are all configured through the included Windows software.

Power is supplied by an included ½ AA 3.6V lithium battery giving up to 6 Months of operation. The unit measures 134.5 mm (5.3 in) in overall length by 25.3 mm (0.99 in) in diameter and weighs 114 g (4 oz). The logger carries CE marking and is manufactured under ISO 9001 certification.

Configuration Options

This series is supplied as a single model, the OM-EL-USB-TC-LCD, whose capability lies in its support for three thermocouple types from one unit.

By selecting the thermocouple type in software, the same logger can measure across the Type K range of -200 to 1350°C (-328 to 2462°F), the Type J range of -200 to 1190°C (-328 to 2174°F), or the Type T range of -200 to 390°C (-328 to 734°F). Temperature can be displayed in °C or °F, also selectable in software.

On-unit feedback is provided by a 4-digit LCD and status indication through red and green LEDs, and 2 user-programmable alarm thresholds flag high or low temperature excursions. Logged data can be graphed, printed, and exported to other applications such as Excel.

Key Product Differences

The series is ordered with the following model numbers:

• OM-EL-USB-TC-LCD — thermocouple data logger with LCD display and USB interface, supplied with measurement leads, software on CD, and battery.
• OM-EL-BATT — replacement 3.6V lithium battery.

An OMEGACARE extended warranty program is available, adding three years to the standard 1 year warranty.
