| Connection box type | Model | Schematic diagram |
| Simple type | WR□K－101 WR□K2－101 |  |
| Water-proof type | WR□K－131 WR□K2－131 |  |
| Quick coupling type | WR□K－151 WR□K2－151 |  |
| Aviation socket type | WR□K－161 WR□K2－161 |  |
| Handle type | WR□K－187 WR□K2－187 |  |
| Extension wire type | WR□K－191 WR□K22－181 |  |
Note:
(1)WRNK-101 can be used to replace the inner core of assembly thermocouple. (2)Extension wire type usually is attached with 500mm lead wire,if need to add,please indicate the length.
(3) The measuring terminal is supplied with insulation type. If it needs to be connected with the shell, change the model mantissa“1”to“2”,“7”to "8". for example 131 is changed to be 132;187 is changed to be 188.
(4) Refer to Page 26-28, Table 6 and Fig 35 for the graduation mark,measurement range. Response time, diameter and available length of the sheathed thermocouple.
