GENERAL DETAILS
The high temperature sensors should be considered as part of the traditional range of sensors with the difference that electronic portion is completely separate from the sensing part which is in the form of an extension and can withstand temperature up to 250°C.
These products are used to control the levels of hot materials such as liquids, oil, powder and plastic granules.
They also sense solid metallic and non-metallic bodies positioned in areas of high temperature.
The connecting cable between the sensor and the amplifier must be of standard length (2M or 5M). It is not capacitive, it resists to temperatures from - 200 to +250°C it is connected to the sensor and it is provided with a screened connector for connection to the amplifier.
The amplifier is supplied in two different types, model ALSC-1CH which is suitable for one sensor and model ALSC-2CH which is suitable for two sensors, the model ALSC-1CH can be supplied with delayed sensing.
The sensors can be supplied in the following formats M18x1 and M30x1.5 made of stainless steel and PTFE. |

INSTALLATION INSTRUCTIONS
If the material to be controlled is in a metallic container check that it is earthed and connect terminal 3 of the amplifier to the earth.
If the container is not metallic, connect terminal 3 of the amplifier and the body of the sensor SC… M-HT to the earth by using the relative terminal.
The connection wire between the sensor and the amplifier must be separated from the power supply. |
