Temperature Sensors
HEL-700 Series
Platinum RTDs
FEATURES
HEL-700Serieselementsarefullyassem-
bled, ready to use directly or in probe
assemblies without the need for fragile
splices to extension leads.
ɀ Linear resistance vs temperature
ɀ Accurate and Interchangeable
ɀ Excellent stability
ɀ Teflon or fiberglass lead wires
ɀ Wide temperature range
ɀ Ceramic case material
The 1000ȉ, 375 alpha version, provides
10X greater sensitivity and signal-to-
noise. Optional NIST calibrations im-
prove accuracy to ±0.03°C at 0°C.
TYPICAL APPLICATIONS
ɀ HVAC – room, duct and refrigerant
equipment
ɀ Instrument and probe assemblies –
temperature compensation
ɀ Process control – temperature
regulation
