name of document: 30910022 index c status: 01/2012 platinum resistance temperature detector m 620 m series prtds are designed for large volume applic ations where long term stability, interchangeabilit y and accuracy over a large temperature range are vital. due to the hig h resistance values of 1000 w and 2000 w the signal gain is excellent. typical applications are found in automotive, white goods, hvac, medical and industrial equipment. spezification din en 60751 (according to iec 751) temperature range -70c to +500c (continuous operation) (temporary use to 550c possible) tolerance class b: -70c to +500c temperature coefficient tcr = 3850 ppm/k leads pt clad ni- wire recommend connection technology: welding, crimping and brazing lead lengths (l) 10mm 1mm longterm stability max. r 0 -drift 0.04% after 1000h at 500 c vibration resistance at least 40g acceleration at 10 to 2000 hz, depends on installation shock resistance at least 100g acceleration with 8ms half sine wave , depends on installation environmental conditions unhoused for dry environments only insulation resistance > 100 m w at 20c; > 2 m w at 500c self heating 0.3 k/mw at 0c response time water current (v= 0.4m/s): t 0.5 = 0.08s t 0.9 = 0.25s air stream (v= 2m/s): t 0.5 = 3.7s t 0.9 = 11.5s measuring current 1000 w : 0.1 to 0,3ma 2000 w : 0.1 to 0,3ma (self heating has to be considered) note other tolerances, values of resistance and wire lengths are available on request. nominal resistance r0 tol erance din en 60751 1996-07 tolerance din en 60751 2009-05 o rder number pl astic bag 1000 ohm at 0c class b f 0. 3 32 208 181 2000 ohm at 0c class b f 0. 3 32 208 541 the measuring point for the nominal resistance is d efined at 8mm from the end of the sensor body. we reserve the right to make alterations and techni cal data printed. all technical data serves as a gu ideline and does not guarantee particular properties to any products. 1901 route 130 north brunswick, nj 08902 phone 732-940-4400 fa x 732-940-4445 email info.hst-us@heraeus.com http://heraeus-sensor-technology-us.com heraeus sensor technology usa
