The MSR 12 system comprises a basic unit together with optionally available additional modules. Alongside a real-time clock, the basic unit includes the following modules as standard: 3-axis accelerometer, air pressure and ambient temperature sensors. The unit’s functionality may be expanded at any time with an almost unlimited range of external additional modules, allowing it to be customised to the required level.
Each additional module has a range of sensors – mostly of a similar type. Connecting existing, commercially available sensors is also straightforward. For test purposes the gradient curve and the actual measurement parameters for the selected sensor can be shown on the unit's display. The sensor’s signals are processed by the module's own processor and the values saved in the module’s memory.

MSR additional modules ("plug-in modules")
You can put together your custom MSR unit from a wide range of different measurement modules. The following two measurement modules are already included in the standard MSR basic unit:
- Module PR3 measures air pressure and ambient air temperature
- Module ACC3 is a 3-axis accelerometer
The MSR can be upgraded individually using the modules listed below. Should one of your required measurement parameters not be listed, then please contact us for further information. We will be happy to advise.
The following MSR plug-in modules are already in daily use:
| Humidity |
| T24HUM8 |
The T24HUM8 additional module for the MSR processes and logs the values measured by external temperature or humidity sensors. |
| A2D5HUM1 |
The A2D5HUM1 plug-in module records two input voltages, the level of five digital inputs, the signal from one humidity sensor and the temperature of the humidity sensor. Either the instantaneous value or the average, minimum and maximum values can be logged. In addition, a threshold value can be set and an event triggered should this threshold be exceeded. |
| Temperature |
| T24HUM8 |
The T24HUM8 additional module for the MSR processes and logs the values measured by external temperature or humidity sensors. |
| Air pressure |
| PR8 |
The PR8 pressure module processes and logs pressure and temperature values from external pressure sensors. |
| Fluid pressure |
| PR8 |
The PR8 pressure module processes and logs pressure and temperature values from external pressure sensors. |
| AIN4-10 |
The universal module AIN4-10 records and logs four input voltages. For prototyping applications this unit can also be used with additional inputs and outputs. The firmware can easily be modified to suit the required application. |
| AIN4-12 |
This universal module is particularly suited to prototyping applications. It has a range of analogue and digital inputs and outputs. The firmware can easily be modified to suit the required application. |
| Compressed air/valve-tester |
| Valve-tester |
The valve tester measures the delay time between the control pulse and the output signal. It logs this time together with the value of the output signal and a time stamp. In addition, the delay time is analysed. |
| 3-Axis acceleration |
| 3ACCF |
The 3ACCF accelerometer module processes and logs measurements from an external acceleration sensor. |
| Voltage/Current (el.) |
| AIN4-10 |
The universal module AIN4-10 records and logs four input voltages. For prototyping applications this unit can also be used with additional inputs and outputs. The firmware can easily be modified to suit the required application. |
| AIN4-12 |
This universal module is particularly suited to prototyping applications. It has a range of analogue and digital inputs and outputs. The firmware can easily be modified to suit the required application. |
| A2D5HUM1 |
The A2D5HUM1 plug-in module records two input voltages, the level of five digital inputs, the signal from one humidity sensor and the temperature of the humidity sensor. Either the instantaneous value or the average, minimum and maximum values can be logged. In addition, a threshold value can be set and an event triggered should this threshold be exceeded. |
| ECG |
| ECG |
This plug-in module serves to record an ECG signal. The unit can also compute the pulse (heart rate). |
| Heart rate (transmitted via radio) |
| POLAR |
The HR plug-in module processes and logs the heart rate (pulse) measured by the POLAR transmitter chest strap. |
All additional modules can be freely combined with one-another. We would be pleased to advise you on our existing standard module combinations.
The range of sensors is under continuous development and will be adapted to meet customers' requirements. Plug-in modules are planned or under development for the following fields:
- Blood pressure
- Breathing pattern
- Field strength
- Force-displacement (strain gauge)
- Gas analysis
- Position (GPS)
- Pulse
- Speech/sound recording
- SPO2 (oxygen)
- Velocity
The sensors
The major advantage offered by the MSR is that you only need one measurement device for the most diverse applications and sensors.
Connecting commercially available sensors to the Modular Signal Recorder is straightforward. The sensors are recognised automatically and the measurement parameters appear immediately on the unit's display.
