Abstract

A detection system with a measuring head, which has a mount for at least one interchangeable sensor, with a component, which is located at the sensor and receives information on the sensor and transmits same to a detection means at the measuring head. Wireless transmission of the sensor information to the measuring head is provided wherein the component is a passive transponder that can be read by supplying external energy in a wireless manner. The transducer includes a data code carrier, in which the sensor information is stored. The detection means has means for supplying the external energy and means for receiving the sensor information.

Claims

1. A detection system, comprising:

a measuring head with a mount and a detection means;

an interchangeable sensor mounted in said mount;

a passive transponder located adjacent to said sensor, said passive transponder containing information on said sensor and transmitting the information to said detection means at the measuring head, said passive transponder information being read by supplying external energy in a wireless manner, said passive transponder including a data code carrier, in which the information is stored, said detection means including energy supply means for supplying the external energy and sensor information receiving means for receiving the sensor information; and

a sensor front-sensor filter that is detachable from said sensor, wherein said transponder is arranged at said front-sensor filter.

2. The detection system in accordance with claim 1, further comprising an additional interchangeable sensor mounted in said mount, said interchangeable sensor and said additional interchangeable sensor being interchangeably inserted into said measuring head.

3. A gas detection method comprising:

providing a measuring head with a mount and a detection means;

providing interchangeable sensors of various types which are mountable in said mount in at least one sensor position, each sensor having a component that is detachable from said sensor said component being a front-sensor filter of said sensor;

providing a passive transponder located adjacent to each of said sensors, and arranged at said component, each of said passive transponders containing information on an associated said sensor filter and transmitting the information to said detection means at the measuring head when said associated sensor is in said at least one sensor position, said passive transponder information being read by supplying external energy in a wireless manner, each of said passive transponders including a data code carrier, in which the information is stored, said detection means including energy supply means for supplying the external energy and sensor information receiving means for receiving the sensor information; and

using one or more of said passive transponders at corresponding said sensors of various types, which can be interchangeably inserted into said corresponding measuring head.

4. A gas detection system, comprising:

a measuring head with a mount and a detector;

an interchangeable sensor mounted in said mount;

a passive transponder located adjacent to said sensor, said passive transponder containing information on said sensor and transmitting the information to said detector at the measuring head, said passive transponder information being read by supplying external energy in a wireless manner, said passive transponder including a data code carrier, in which the information is stored, said detector supplying energy and receiving the sensor information;

a component that is detachable from said sensor, wherein said transponder is arranged at said component and wherein said component is a front-sensor filter of said sensor.

5. A gas detection system, comprising:

a measuring head with a mount and a detector;

an interchangeable sensor mounted in said mount;

a component that is detachable from said sensor;

a passive transponder being arranged at said component, said passive transponder containing information of said component and transmitting the information to said detector at the measuring head;

a wireless energy supply device for supplying external energy in a wireless manner to said passive transponder, said information being read by supplying external energy in a wireless manner; and

a data code carrier included in said passive transponder, said data code carrier storing information of said component, said detector including said wireless energy supply device and supplying energy and receiving the component information.

6. The gas detection system in accordance with claim 5, wherein said component is a front filter of said sensor and filter data belonging to said front filter are stored in said data code carrier.
