Low cost multi-point pressure measurement


The nanoDaq-LT is a new development by Chell Instruments utilizing the latest technology in digital transducers.

The nanoDaq-LT is a fully configurable smart pressure scanner that will output pressure data in engineering units over Ethernet and CAN. The data output over all interfaces is identical to the nanoDaq-LT's sister products; the nanoDaq and the MicroDaq.

The size of the nanoDaq-LT package makes it unique for a smart digital output device enabling pressure scanning to be used in challenging applications in terms of space and environment.

The nanoDaq-LT makes use of 17 absolute transducers which are thermally compensated and conditioned to provide either 17 absolute measurements or 16 differential measurements relative to one reference port.

The user can select a number of operating parameters using the embedded web server. These include; absolute or differential, TCP and UDP setup, data averaging and units, CAN setup and time stamp configuration.

The nanoDaq-LT features a hardware implementation of the IEEE 1588 PTPv2 time stamping protocol which allows the pressure data to be time stamped to a resolution of 1μSecond.

The nanoDaq-LT also features a hardware trigger allowing the pressure acquisition to be synchronised to an external TTL pulse.

The nanoDaq-LT is contained within a miniature package which is sealed to IP67 enabling it to be used in harsh environments. It is also available with alternative packaging to suit particular applications - please contact us for more details.

The transducers within the nanoDaq-LT have a very high proof pressure(50psig, 64.5 psia) which reduces the chances of in-field transducer damage.

Another advantage of the transducer configuration within the nanoDaq-LT is the very low transducer volume(20㎣) - including the reference.
