Description

The Chell 2432T is a complimentary product to our existing line of 2432, 2416, flightDAQ and microDAQ pressure scanner products.

Using the powerful Chell architecture and interfaces enables the 2432T to accurately measure 32 thermocouple inputs and the corresponding cold junction temperatures, 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® emulation mode.

The 2432T consists of 32 pairs M3 screw terminal inputs together with a ground connection per thermocouple. These inputs are embedded into a high-grade copper Uniform Temperature Reference (UTR) to ensure a uniform cold junction temperature.

The cold junction temperature is measured by multiple precision temperature sensors and RTD’s  to calculate the cold junction temperature across the UTR.

The hot junctions are measured by individual 24-bit high quality ADC’s per channel. This not only allows us to acquire all channels synchronously but also gives greater than 1000V isolation between the channels.

The 2432T offers Open-Circuit-Detection (OCD) to detect breaks or shorts in the thermocouples and also Sensor-Impedance-Measurement (SIM) which uses a proprietary method the measure the total impedance of the thermocouple connected to scanner. This measurement is provided to the user as a useful system diagnostic and to assist in early thermocouple failure detection.

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 or by XML file download.

The user can choose between a number of standard look-up-tables (B,E,J,K,N,R,S and T-Type) or enter their own for conversion to engineering units of their choice (maximum size 448 lines – downloadable from a CSV file).

The 2432T features a power supply that can use PoE or conventional DC.
