Modular Sensor Interface MSI 60

The MSI 60 is a high quality signal conditioning and data acquisition unit for analogue, digital, frequency and linear variable differential (LVDT) sensors.

MSI 60 offers a large number of freely configurable inputs (32 x differential analogue, 8 x single ended analogue, 8 x LVDT, 2 x frequency, 1 x RS 232 for GPS). Possible applications of the differential inputs include e.g. 31 TC-J type or TC-K type temperature sensors arranged in a sensor array (one diff. input used for compensation), PT100, PT1000 (specific pull up values available), NTC, strain gauges etc. Each differential input features 200 times oversampling.

The cut-off frequency of the digital filters in all inputs is automatically adjusted to match the acquisition rate. MSI 60 also corrects the latency of the digital filters during recording, yielding zero filter delay in the recorded data. Quantization of each MSI measurement channel is individually configurable. Data can be sent via Ethernet interface to any Bosch Motorsport logging device.
