RTD Sensors
HEL-777/776 Series
100 Ohm or 1000 Ohm platinum RTD. -55°C to 150°C. Molded plastic housing SIP
The HEL-776/HEL-777 Series 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 with 0.050 in 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. Both are ideal for air temperature sensing.
