A transmitter, in particular for mounting on the head of a process thermometer, has an upper part, a lower part, at least one connection unit and at least one electric contact element. The connection unit is arranged on the inside of the upper part and can be electrically contacted via the contact element from the outside of the upper part. The lower part is integrally formed using thermoplastic plastic and the upper part and the lower part are force-fit and/or form-fit with one another. A method for making the transmitter is also disclosed.

1. A transmitter for mounting in the head of a process thermometer, said transmitter having an upper part, a lower part, at least one circuit unit and at least one electric contact element, wherein the circuit unit is arranged on the inside of the upper part and can be electrically contacted via the contact element from the outside of the upper part and wherein the lower part is integrally formed using thermoplastic plastic and the upper part and the lower part are force-fit and/or form-fit with one another, wherein the lower part encloses the circuit unit arranged in the upper part, and wherein the lower part fits essentially completely on the inside of the upper part. 2. The transmitter according to claim 1, wherein the thermoplastic plastic is a material from the polyamides group or includes a material from the polyamides group. 3. The transmitter according to claim 1, wherein the lower part closes essentially even with the lower edge of the upper part. 4. The transmitter according to claim 1, wherein a feedthrough is provided through the lower part and the upper part, the feedthrough is formed in the upper part and the feedthrough is provided centrally in the transmitter. 5. The transmitter according to claim 1, wherein projections are formed in the upper part and corresponding projections are formed in the lower part, and wherein the projections of the upper part and the projections of the lower part support one another in the assembled state of the transmitter so that the upper part and the lower part are latched to one another. 6. A method for producing a transmitter wherein the transmitter has an upper part, a lower part, at least one circuit unit and at least one electric contact element, wherein the circuit unit is arranged on the inside of the upper part so that it is electrically contacted via the contact element from the outside of the upper part, said method comprising the steps of arranging the upper part in a form with the circuit unit, heating a thermoplastic plastic to working temperature and integrally forming the lower part by casting or injecting the thermoplastic plastic in the form and on the inside of the upper part, so that the lower part and the upper part are connected to one another with force fitting and/or form fitting. 7. The method according to claim 6, including the step of choosing as the thermoplastic plastic a material from the polyamides group or a material that includes polyamides. 8. The method according to claim 6, including the step of carrying out the casting or injection process in less than 30 seconds.
