Frequently asked questions

Common questions about OMEGA Thermocouple from 3G Electric.

How do I choose between a general purpose, surface or liquid and gas OMEGA thermocouple?

Match the sensor to how heat reaches the junction. General purpose probes suit immersion in ducts and tanks, surface types clamp or bond to plates, rolls and pipework, and liquid and gas assemblies use sealed or threaded fittings for pressure lines. Confirm thermocouple type, sheath material and temperature range before ordering.

Do OMEGA thermocouple connectors and extension leads need to match the probe type?

Yes. Plugs, jacks, multipin connectors, terminal blocks and extension leads are alloy-specific, so a type K plug on a type J circuit introduces error at every junction. Order the same calibration letter as the thermocouple, and use extension grade wire only to the point where the signal reaches the instrument.

What lead time applies to OMEGA thermocouples and accessories shipped worldwide?

Stocked plugs, terminal blocks, adapters and common probe styles ship quickly from available inventory, while non-standard lengths, sheath materials and multipin configurations are quoted on request. Send your part numbers, quantities and destination and we will confirm availability and delivery.
