The DTS4050 is a direct replacement for its predecessor, the DTS3250. The DTS4050, Digital Thermocouple Scanner, accepts 16, 32, or 64 thermocouple inputs. It incorporates integral low pass filters, 22 bit A/D converters, and a DSP microprocessor. The DTS module is specifically designed for high-noise environments and as such can withstand unmatched common mode noise. An isothermal block is incorporated for the Uniform Temperature Reference (UTR) for each 16 channel input. NIST thermocouple tables for standard thermocouple types are stored in flash memory. The microprocessor uses these look-up tables to convert mV inputs to Engineering Units. Temperature data are output in °C, °F, °R, K, millivolts and counts. The DTS4050 accuracy for types E, J, K, N, and T is ± .25°C to ±0.5°C depending on the thermocouple type and the useful temperature range. (Refer to accuracy table for a complete listing of supported thermocouples and associated accuracies) Multiple standard thermocouple types may be used with one DTS4050. Applications The DTS4050 Digital Temperature Scanner is ideal for use in turbine engine, diesel engine, and compressor test cells, as well as other industrial environments such as boiler and oven temperature monitoring. The module has a corrosion resistant, stainless steel enclosure with a locking lid for input terminal access. The standard DTS is insulated, rugged, and splash resistant and incorporates shock mounts for vibration isolation. The DTS4050’s electronics were specifically designed to endure punishing high EMI noise environments while still being able to provide accurate engineering data. The DTS4050 is typically mounted in close proximity to the test article, thus minimizing thermocouple wire lengths. Shorter thermocouple wires not only reduce errors, but also lower costs due to the elimination of extension cables. Field calibrations can be used to modify coefficients which can also improve overall system accuracy. The standard DTS4050 module accepts two wire or three wire shielded thermocouples.

Common Mode Rejection The DTS4050 has a hardware supported slave implementation of the Precision Time Protocol defined by IEEE 1588-2008, otherwise known as PTP V2. This protocol is used to synchronize the DTS4050 internal clock over the Ethernet network. The DTS4050 product line was specifically designed to operate in environments with high levels of EMI. The DTS’ unique architecture allows it to precisely read microvolt signals even amongst hundreds of volts of common mode noise. Supporting this capability, the DTS is built around a robust front end. Every thermocouple input channel has its...

DTS4050 Communications The DTS4050 module interfaces directly to a host via an Ethernet connection. Scanivalve’s free ScanTel communications program is designed to assist a user in establishing communications and data collection, as well as configuring the DTS module. Additionally available is a Software Development Kit for users who want to write their own detailed data acquisition program in LabVIEW®. This Development Kit includes the Configuration Utility software and examples to assist a user in the setup of the system. An OPC driver is also available (16Tx only).
