Resistance Temperature Sensors

Watlow manufactures a complete line of resistance temperature sensors that include resistance temperature detectors (RTDs), thermistors and the ENVIROSEAL™ HD temperature sensor for heavy duty applications in harsh environments. Watlow's platinum resistance elements are specially designed to ensure precise and repeatable temperature measurement. RTDs and thermistors are accurate, sensitive, standardized and interchangeable.

Product		Description	Temperature		Accuracy
Product		Description	°F	°C	Accuracy
	RTDs	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)
	Thermistors	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.	-58 to 500	-50 to 260	n/a
