These thermocouple probes provide a quick and convenient method for measuring temperature in your process. They can be used as-is, mounted into your process using one of Omega's line of Compression Fittings, or used in a thermowell by using one of our Spring Loaded Fittings.
The M12 Series thermocouple probes are available as Type K thermocouples with Inconel 600 sheaths, or as Type J thermocouples with 304 Stainless Steel sheaths. Standard probe sizes include 1/4" and 1/8" diameters with lengths of 6", 9", 12", 18" and 24", and metric sizes in 3mm and 6mm diameters with lengths of 250, 500, 750, 1000 and 1500mm. These thermocouple sensors can also be requested in other lengths as needed.
The connectors on these sensors are overmolded with the IEC standard color code on the metric sizes and the ANSI standard color code on the fractional sizes. The connector pinout is as shown in the accompanying figure.
To connect this sensor to your measurement or control instrument, we recommend using one of Omega's M12 Extension Cables (listed in the ordering table below). Besides these extension cables, Omega offers a selection of specially assembled extension cables in a variety of cable materials with optional stainless steel braid or hose for improved mechanical protection, and a wide selection of instrument connections.
