| General Description | The ST650 EX is an all-round gas detector which functions well under the most difficult circumstances. The sensor is available in various versions, such as a catalytic flammable gas sensor, Infrared (NDIR) and a Thermal Conductivity sensor (TCD). The sensor has a long life-span, which achieves an optimal cost of ownership. |

| Mounting | Mount the detector in a vertical position, with the sensor pointing downwards. |
| Installation Clearance | Leave at least 11 cm free space below the sensor head to ensure the splashguard can be removed during sensor exchange. This also allows connection of a hose for bump tests. |
| Connections | Follow the original manufacturer connection diagram on source page 5; terminal allocation is not reproduced here. |
| Remote Application (family Remote Condition) | Remote sensors are ideal where gases ascend. Cable lengths up to 150 metres are supported between transmitter and sensor (depending on type). |
