Richards Thermocouple elements can be designed in many configurations. Some of the more common forms are shown below. If you need a special type, phone one of our sales engineers and we can make them to your requirements. The part numbers below describe the thermocouple element type, wire gauge, method of insulation, and construction. See the catalog number key below.

Catalog Number Key

1. Thermocouples Types E, J, K, N, and T are Special limits of error.

2. Thermocouples Types B, C, R, and S are Standard limits of error.

3. Wire Gauge number is shown in the left hand column and is the first character in the catalog number.

4. The Type of thermocouple curve is the second character.

5. The next number refers to the style.

6. Replace the * with the length. 6 inch (152.4 mm) multiples are standard but non-standard lengths are available.
