Abstract

For a liquid-, or gas-, sensor composed of a sensor module SM and a sensor module head SMK, which are pluggably connectable together and which enable when plugged together an exchange of data and energy via a galvanically decoupled, transfer zone, a pluggable module ST1, or ST2, as the case may be, is provided, which is connectable with the sensor module SM, or with the sensor module head SMK, and which serves for display of sensor data stored in the sensor module SM, or for simulation of a measured value.

Claims

1. A pluggable module (STI) for a liquid-, or gas-, sensor, which sensor includes a sensor module (SM) and a sensor module head (SMK), which are pluggably connectable together and which enable, when plugged together, an exchange of data and energy via a galvanically decoupled, transfer zone, wherein:

the pluggable module (ST1) is connectable with the sensor module (SM) and has a display unit, which serves for display of sensor data stored in the sensor module (SM), and

the pluggable module (STI) and the sensor module (SM) enable, when plugged together, an exchange of data and energy via a galvanically decoupled transfer zone.

2. The pluggable module (STI) as claimed in claim 1, wherein:

the pluggable module (STI) is embodied in the form of a key-ring pendant.

3. A pluggable module (STI) for a liquid-, or gas-, sensor, which sensor includes a sensor module (SM) and a sensor module head (SMK), which are pluggably connectable together and which enable, when plugged together, an exchange of data and energy via a galvanically decoupled, transfer zone, wherein:

the pluggable module (ST1) is connectable with the sensor module (SM) and has a radio unit, which serves for transmission of sensor data stored in the sensor module (SM),

the pluggable module (STI) and the sensor module (SM) enable, when plugged together, an exchange of data and energy via a galvanically decoupled transfer, and

the pluggable module (STI) is embodied in the form of a key-ring pendant.

4. A pluggable module (STI) for a liquid-, or gas-, sensor, which sensor includes a sensor module (SM) and a sensor module head (SMK), which are pluggably connectable together and which enable, when plugged together, an exchange of data and energy via a galvanically decoupled, transfer zone, wherein:

the pluggable module (ST1) is connectable with the sensor module (SM) and has a fieldbus interface (Profibus, Foundation Fieldbus, HART), which access to sensor data stored in the sensor module (SM) occurs,

the pluggable module (STI) and the sensor module (SM) enable, when plugged together, an exchange of data and energy via a galvanically decoupled transfer zone, and

the pluggable module (STI) is embodied in the form of a key-ring pendant.

5. A pluggable module (ST2) for a liquid-, or gas-, sensor, which sensor includes a sensor module (SM) and a sensor module head (SMK), which are pluggably connectable together and which enable, when plugged together, an exchange of data and energy via a galvanically decoupled transfer zone, wherein:

the pluggable module (ST2) is connectable with the sensor module head (SMK) and has a simulation unit, which produces an analog signal value, which simulates a measured value and which is converted in a signal processing unit into a digital measured value, which is forwarded to the sensor module head (SMK), and

the pluggable module (ST2) is embodied in the form of a key-ring pendant.
