The nanoCAT-LTR is a new development by Chell Instruments utilizing the latest technology in digital transducers.
The nanoCAT-LTR is a fully configurable smart pressure scanner that will output pressure data in engineering units over EtherCAT and CAN.
The use of EtherCAT gives the user the following advantages:
 Increased bandwidth. EtherCAT is many times more efficient than Ethernet making the acquisition of high speed data from multiple units much more straight forward.
 Non-vendor specific protocol. As the nanoCAT- LT adheres to the EtherCAT standard, no special code needs to be written in order to interface with it.
 Integrated time stamping. The EtherCAT pro- tocol includes a distributed clock that time stamps the data to within ±20μS
 Network topology independent. EtherCAT is insensitive to network topology and the units are designed to be daisy-chained in loop or star configuration.
The nanoCAT-LTR makes use of 66 absolute transducers which are thermally compensated and conditioned to provide 64 either absolute or differential measurements relative to one reference port per bank of 32 channels. The user can configure the nanoCAT-LT-64 to use one reference port fir each 32 channels, one for all 64 channels or the average of both references for all 64 channels.
The nanoCAT-LTR is contained within a miniature package which is sealed to IP67 enabling it to be used in harsh environments. It features two removable top plates than can be ordered with straight or angled (at 60o) 1mm (0.040”) tubulations
The transducers within the nanoCAT-LTR have a very high proof pressure (50psig, 64.5 psia) which substantially reduces the chances of in-field transducer damage.
