Sensorwell
HEL-776-A-U-1
HEL-776 Series temperature sensor, platinum RTD, plastic case SIP
HEL-776 and HEL-777 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″
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.
