Analog I/O module LM-RTD-P

digitalfor temperature sensors4-channel

The RTD-P high-precision measuring module has been developed for applications which place extremely high demands on resolution and measuring accuracy. The RTD-P modules have an extremely accurate analogue-to-digital converter and a precision current source for resistance sensors. The modern process-based circuit design makes compensation elements unnecessary. Thanks to dynamic self-calibration, temperature and ageing effects are reduced to the extremely low long-time drift value of the integrated high-precision reference elements. The temperature sensors are connected via connection sockets to NAMUR standards. • Extremely high measuring accuracy: 0.001 °C • Relative differential measurement uncertainty ±0.003 °C in the measuring range -180 to +266 °C • 4 channels virtually simultaneously recorded in < 1 s • Self-calibrating • Malfunction and short-circuit detection • Signal : Pt100 signal with two- and four-wire connection • Connection type : 4-pin socket, type LEMO S1 • Resolution : 0.001 °C • measuring range : -180…+266 °C • Absolute measurement uncertainty within the maintenance interval) : ±0,08 °C after calibration of the measurement chain • Relative measurement uncertainty (for differential measurement) : ±0.003 °C
