Industrial simulator M641

RTD

M641 is programmable real-resistance decade with parameters designed specifically for RTD sensors' simulation and testing of RTD evaluation units like temperature regulators, transducers, etc. The core function is still resistance so you can as well calibrate ohmmeters and other resistance based meters easily. M641 is made of high load resistors and relays allowing for 5 W load capacity and 0.01°C resolution at the same time. Floating output terminals of M6xx decades allow for AC measurements as well, see datasheet for typical frequency responses. Large LCD shows all related parameters including total accuracy. There is no residual resistance or hidden absolute error. M6XX series can show resistance in temperature, distance, force and other units. Complete recalibration is possible in just 10 minutes. All decades' functions can be remotely controlled via RS232, USB, LAN or GPIB interface. This way you can introduce calibration/test stage directly into production line of any resistance based sensor and reduce time required for final quality tests dramatically. Specifications: Resistance: 10 Ω - 300 kΩ (± 200 ppm / year) max dissipation power 5 W Temperature: RTD (± 0.1°C / year) resolution 0.01°C
