RTD Temperature Transducers

DescriptionDIN rail mounting transducers available in 55mm x 112mm or 100 x 112mm DIN rail casesApplicationUsed to convert various inputs into standard DC signals for driving panel meters and for use in control devices.Selection GuideM100-RTDRTD temperature measurementTypical ApplicationsThe M100-RTD monitors the resistance of either 100 Ohm platinum or 120 Ohm Nickel. The RTDs resistance increase as the temperature rises, this resistance change is detected by the M100-RTD, which provides an output corresponding to the temperature being measured. The temperature versus resistance values are provided by the supplier of the RTD used.RTD measurement of temperature is used in large transformers and large motors to ensure winding temperatures do not rise to a level that would change the winding.Technical SpecificationsINPUT2 or 3 wire inputPlatinum Pt 100 Ohm RTDmin. span 20 Ohms-maxspan 200 OhmsNickel Ni 120 Ohm RTDmin. span 24 Ohms-maxspan 240 OhmsOUPUTRated value mA0-1 / 5 / 10 / 20 & 4-20mARated value volts0-5 / 10 & 1-5VACCURACYClass ±0.5%ADJUSTMENTZero±2%Span±10%AUXILIARYA.C.
