Thermostats and Thermocouples
Go back to Flanged Immersion Heaters
The thermostats used in flanged immersion heaters are the bulb and capillary style. The standard thermostat has 25A max capacity and could operate up to 240V. This thermostat is single pole/single throw style with a temperature range of 10-120ºC. The table below shows other ranges of thermostats that are available.
| THERMOSTAT | CONTACT OPERATION | TEMPERATURE RANGE | MAXIMUM AMPS | MAXIMUM VOLTAGE |
| T | SPST | 100 to 1200 C | 25A | 277V |
| T1 | SPST | -180 to 400 C | 25A | 277V |
| T2 | SPST | 700 to 2800 C | 25A | 277V |
| T3 | SPST | 1600 to 3700 C | 25A | 277V |
| T4 | DPST | 100 to 1200 C | 15A | 600V |
| T5 | DPST | -180 to 400 C | 15A | 600V |
| T6 | DPST | 700 to 2800 C | 15A | 600V |
| T7 | DPST | 1600 to 3700 C | 15A | 600V |
It should be noted that thermostats are only temperature controllers and should not be used as fail-safe high limit switches.
Built-in thermocouples could be used inside flanged immersion heaters to give more accurate temperature indications. Thermocouples could also be attached to one of the heating elements and used as high-temperature limiting devices.
