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.
|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|
