Abstract
A temperature detector for a contact thermometer of process measurement technology having a thermowell, at least one thermal sensor element arranged in a process-side end of the thermowell, and at least one electrical connecting means connected to the thermal sensor element with a first connection side and extending in the thermowell at least up to an evaluation-side end of the thermowell, so that the thermal sensor element can be electrically contacted via a second connection side of the electrical connecting means, and in which the electrical connecting means is formed by a connection printed circuit board with conducting paths.
Claims4
Temperature detector for a contact thermometer of process measurement technology comprising:
- a thermowell having a process-side end and an evaluation-side end,
- at least one thermal sensor element arranged in said process-side end of the thermowell,
- a connection printed circuit board having a first connection side, a second connection side, conducting paths, and at least one conducting area on said second connection side, and
- a contact printed circuit board having at least one contact means and at least one conducting area,
- said connection printed circuit board and said contact printed circuit board being separate printed circuit boards,
