Thermocouple Extension Wire Cable

Thermocouple extension wire has approximately the same characteristics as Thermocouple wire, but its accuracy is guaranteed over a more limited range of temperatures.

Thermocouple extension wire can offer advantages in cost or mechanical properties when used for connections between Thermocouple and instruments.

For base metal types of Thermocouples, extension wire is of substantially the same composition as the corresponding Thermocouple type.

For precious metal types, however, an entirely different alloy is formulated to match the noble metal characteristics over a specified temperature range. This is necessary due to the high cost of the precious metals, which would otherwise be necessary for the interconnection. The X in the IEC and ANSI code denotes extension grade wire.

3 Phase Monitor Time Mark Model 252

The Model 252 3-Phase Monitor continuously monitors 3-phase power lines for abnormal conditions. When properly adjusted, the Model 252 will detect phase loss on a loaded motor even when regenerated voltage is present.

The device consists of a solid-state voltage and phase-angle sensing circuit, driving an electromechanical relay with one SPDT and one SPST contact. When correct voltage and phase rotation are applied, the internal relay will energize. A fault condition will de-energize the relay. When the fault is corrected the Model 252 will automatically reset.

The Model 252 does not require a neutral connection and can be used with Wye or Delta systems. Four versions cover 120V, 208/240V and 480V, 60Hz, and 380V, 50Hz. Adjustment ranges are sufficiently wide to allow for proper adjustment to existing conditions. Two LED indicator are provided to aid in adjustment and system
troubleshooting.
