Watlow's platinum resistance elements are specially designed to ensure precise and repeatable temperature measurement. Watlow RTDs and thermistors are accurate, sensitive, interchangeable, standardized and repeatable.
Accurate, repeatable and interchangeable over a wide operating range.
-328 to 1200
-200 to 650
DIN Class A ± 0.06% at 32°F (0°C) DIN Class B ± 0.12% at 32°F (0°C)
Highly sensitive to small changes in temperature, fairly accurate over a limited temperature range.
-75 to 500
-60 to 260
± 1% at 77°F (25°C) to ±15% at 32°F (0°C)
ENVIROSEAL™ HD Sensor
Suited for heavy-duty applications including those in harsh environments.
-40 to 392
-40 to 200
Same as RTD and thermistor accuracies above
Surface Temperature Sensors
Can be mounted on flat surfaces and is ideal for surface temperature monitoring applications.
