Overview

HEL-775 Series temperature sensor, platinum RTD, ceramic case, SIP.
HEL-775 platinum RTDs are designed to measure temperatures from -55 °C to 150 °C [-67 °F to 302 °F] in printed circuit boards, temperature probes, or other lower temperature applications. Solderable leads in 0.050" or 0.100 in" spacing provide strong connections for wires or printed circuits.

The 1000 Ohm, 375 alpha version, provides 10X greater sensitivity and signal-to-noise. The 0.050 in lead space models are ideal for probes.
