TNK - RTD Temperature Sensors

Brand: KOBOLD Instruments, Inc

The KOBOLD TNK RTD Temperature Sensors are electrical temperature transmitters used in conjunction with appropriate analytical equipment for displaying and regulating temperature.

They are designed for use in shipbuilding and mechanical engineering and offer ruggedness, reliability, impact resistance, shock and vibration resistance in accordance with specifications set by Germanischer Lloyd and German State Railways.

They are ideally suited for temperature measurement in diesel engines.

The sensor is made of brass, bronze, or stainless steel.

The terminal head is made of salt-water resistant aluminum and is available with various cable entry points. Using a variety of fittings, the sensor can be mounted in a pipe or on the machine.

The measuring resistances can be replaced without removing the mounting. With four terminals, it is easy to connect to three or four lead technology.

The sensor is also available as a double measuring resistance.
