热电阻()传感器(型)，电缆探头
The Pt100 cable probe is easy to install and offers high operational safety; it performs reliable, high-precision measurements in general processes. No additional thermowell is required; the mineral-insulated insert of the probe is in direct contact with the process medium. The cable probe detects temperature changes quickly and accurately.
Advantages
User-defined insertion depth for flexible use
Stepped/tapered tip for a short response time
Simple modular structure: excellent value for money. Easy ordering and reordering
Improved electrical isolation (2 kV) when installed on most devices
Application
TH12 is a resistance thermometer (RTD) temperature sensor suitable for the process industry or environmental plant automation. It includes a resistance (RTD) measuring probe, an insulation layer and a mineral-insulated insert.
The sensor can be used for:
Heat exchangers
Energy recovery areas
Carbon regeneration furnaces
Dryers
Flue gas
Compressor stations
Process reactors
