Type S Thermocouple Instructions

The Best Thermocouple

1. The standard thermocouple for DynaTrol or Genesis control is Type K, commonly an 8-gauge exposed Type K thermocouple used on various kiln models.
2. For constant high-fire applications, a Type S platinum thermocouple with an alumina sheath is the best, standard on JH Series kilns and recommended for extreme conditions.

Technical Information

1. Type S thermocouples have legs of platinum and rhodium, usable from 32°F to 2700°F (0°C to 1480°C).
2. They last long at kiln temperatures up to 2400°F if not mechanically damaged.
3. Lead wires for Type S are not interchangeable with Type K.
4. DynaTrol controls made before Jan 1, 2006, and One-Touch controls cannot be retrofitted for Type S.
5. DynaTrol 700 controls (post Jan 1, 2006) can be converted with a lead wire change.

Description:

1. Type S thermocouples have a 5/16” OD alumina sheath and are ungrounded.
2. Two lengths are available:
   • 120 mm (4.75”) for Easy-Fire, Jupiter, eQuad-Pro, JH Series, DaVinci, and Doll kilns.
   • 160 mm (6.3”) for Easy-Load front-loading kilns.
3. Polarity:
   • Black Wire = PLUS (+)
   • Red Wire = MINUS (-)

6. Type S thermocouples can be ordered with any kiln having a DynaTrol or Genesis Control.

Retrofitting Cautions:

1. Check the configuration of any replacement control to avoid melting your kiln.
2. Replacement controls typically have the standard configuration for Type K thermocouples with 3-zone control.
3. Ensure the control configuration matches your thermocouple type.
4. Incorrect configuration (Type S thermocouples with Type K control) can cause severe over firing to the point of melting the elements, element channels and brick.
5. Type K thermocouple extension wire is yellow or brown; Type S extension wire is green (in the USA).
