The TMI conditioner is designed to perform accurate multi-channel temperature measurements and is compatible with FOT-L/H and FOT-M temperature sensors. Thanks to its unique, patented technology, the TMI conditioner is capable of measuring the absolute cavity length of FISO’s Fabry-Perot fi ber optic sensors with astonishing accuracy, providing highly accurate and reliable measure ments. The TMI has a 0.01% full-scale resolution and a 0.025% full-scale precision.FISO’s fi ber optic sensors offer complete immunity to RF and microwave radiation with high temperature operating capability, intrinsic safety, and non-invasive use.The TMI comes in a 4-channel or in an 8-channel version. All optical input channels are easily accessible through the unit’s front panel. The system scans all the chan- nels in use sequentially with a switching time of 0.15 seconds. It can also read on a discrete channel at a 20 Hz sampling rate. Data is stored in the internal memory buffer for later retrieval or sent directly to any analog input signal reading device through the ±5 V adjustable analog output available for each channel on the back panel of the TMI unit.The TMI conditioner has a non-volatile memory buffer that can store up to 50 000 data points. Data logging sequences, duration, and other acquisition and data- management parameters are easily programmable using the front-panel interface, through remote control commands or, even more easily, thanks to its accompanying software, FISOCommander. Moreover, a Flash ROM allows fi rmware upgrades.The TMI is the only test unit that can be upgraded to a multi-parameter condition-er to measure temperature, pressure, strain, refractive index, and displacement.
