PRECISION 2/3 WIRE RTD SENSOR TO USB ADAPTER DESCRIPTION The RTD300 is an interface for temperature measurements using most of 2- or 3-wire 100 ohms RTDs, such as the popular PT100 probes. Built around a 24-bit data converter combining cutting-edge technologies, the RTD300 brings unmatched precision and resolution to your temperature values, with an improved sample speed. Furthermore, the RTD300 compensates the measured value of errors introduced by the length of a 3-wire probe cable, up to 100 feet, and drastically reduces electronic noise, thanks to its sophisticate’s builtin digital filters. Sensors connect using a convenient and industry standard mini RTD 3-pin connector. It’s compact USB-key form factor simplifies integration even in space-constrained applications. ◌ Research & development ◌ Aerospace ◌ Biomedical ◌ Robotics ◌ Environmental chamber ◌ Pre-certification ◌ Server rooms ◌ Building automation ◌ Green house ◌ Manufacturing ◌ Engineering INSTALLATION TIME Less than 10 minutes UNIQUE SERIAL NUMBER Each unit is assigned a unique serial number allowing for traceability and certification FREE DAQ SOFTWARE Real-time data visualization and logging DATA INTEGRATION Command-line tools for direct data access and integration SPECIFICATIONS Parameter SPECIFICATIONS Value Power supply Temperature Unit operating range ADC resolution Temperature resolution Probe dependant - 200 to 600 °C – 24 bits Typ. 0.0005 °C Typ., at 25°C Accuracy[4] ±0.001 °C Excluding probe Noise level Typ., at 25°C 0.0015 °C Samples rate Up to 10 SPS 100 ms Response time t63% Probe dependant Sensing element type RTD 100 Ohms Factory calibrated Individually[2] Yes – Calibration value point – 0.0000 °C Temperature At 25°C, minimum, 5 min stabilisation time following power-up Pre-wired PT100 probe See image Yes – available (optional) below ○ Virtual COM Port (VCP) communication protocol ○ 3-point user calibration mechanism ALSO AVAILABLE Traceability certificates Dracal Technologies Inc.

Each sensor is individually calibrated by Dracal technologies and their correction coefficients are stored in each of them. [3] If water condensation is possible, it is recommended to install the probe pointing down to reduce the risk of water build-up in the sensor. If water splashing is possible, protect the sensor and cable converter using extra precautions. Extra housing may be required depending on the application.
