HEL-700 Thin Film Platinum RTDs (Re-

sistance Temperature Detectors) provide

excellent linearity, accuracy, stability and

interchangeability. Resistance changes

linearly with temperature. Laser trimming

provides ±0.3°C interchangeability at

25°C.

1000V, 375 alpha provides 10X greater

sensitivity and signal-to-noise. Both

1000Vand 100Vprovide interchange-

abilities of ±0.6°C or better from -100°C to

100C, and ±3.0°C at 500°C.
