1.1 Introduction
The Chell FlightDaq-TL is a complimentary product to our existing line of
FlightDaq and Q-Daq pressure measuring equipment.
Using the powerful architecture and interfaces enables the FlightDaq-TL to
accurately measure a large variety of input types, convert the measurement to
engineering units and then output the data over a number of configurable
Ethernet interfaces. These interfaces can be the Chell protocol (TCP/IP or
UDP), IENA, iDDS or NetScanner® simulation mode.
The FlightDaq-TL consists of 16 x 8-pin Lemo® 1B series inputs each of which
contain two inputs (one primary and one secondary), switchable excitation and
a digital interface for the optional Smart Lemo® plugs.
The 16 inputs can be individually configured to provide measurements for the
following:
•
Voltage (one differential, one single-ended)
•
Resistance
•
Thermistor
•
Thermocouple inputs (using external cold junction such as a Smart
Lemo®).
•
RTD385
•
Amplified pressure transducer
•
Ratiometric pressure transducer
The FlightDaq-TL can be configured for any combination of channels without
comprising speed or performance (with the exception of the 24V excitation
which must be applied to all channels).
Configuration of the inputs and the output stream is carried out via an embedded
web server, using commands over the selected protocol or via an iDDS
configuration server by XML file download.
The user can choose between a number of standard in-built look-up-tables
(RTD385, N-Type etc) or enter their own for conversion to engineering units of
their choice (maximum size 448 lines - downloadable from a CSV file).
Alternatively, if used with the compatible Smart Lemo®’s, this LUT can be stored
in the connector and therefore remains physically tied with the transducer.
The FlightDaq-TL has a programmable excitation source available to all
channels. This can be configured to be +5, +10 or +24VDC.
The FlightDaq-TL features PoE as standard but can be user configured (via
internal switches) for conventional DC supply.
This manual supports V1.0.8 of the FlightDAQ-TL firmware. If using a unit with
earlier firmware, some documented features may not exist or function as
described here.
