ISBH ITS-RTD - Vysokopresný USB systém na meranie teploty pomocou RTD
Vysokopresný USB systém na meranie teploty pomocou RTD
ITS-RTD is a new and special type of a complete high precision temperature measurement system with integrated data logging and graphical functions for the direct connection to any PC/laptop via the USB port. This ISAscale® product is based on a technical PRT in connection with the high precision data acquisition system ISA-ASIC from ISABELLENHÜTTE. Different types of high precision Pt100 sensors according to EN 60751 and ITS-90 are used. The sensor and the measuring system are an inseparable and calibrationable unit. The signal, which is determined in a true ohm 4 wire measurement process, is measured with the offset-free, low-noise ISA-ASIC measurement system at a 16 to 20 bit resolution. The absolute resolution and noise is better than 1 mΩ or 0.004 K (4 mK) in the stated temperature range. The ITS-RTD is calibrated as a unit including sensor and electronic circuit. The accuracy is better than 0.05 K in the full temperature range. The system works on the USB bus, i. e. the circuit is powered via the bus, and it communicates with any PC or laptop based on Windows® 2000/XP/VistaTM (32 bit). Each sensor has an individual address allowing the parallel operation of several units with one PC/laptop.
