Sensor Types and Trip Point Ranges:
• 2-Wire 100 Ω Platinum RTD DIN curve (385): -100 to
850°C (-148 to 1,562°F)
• E Thermocouple: 100 to 801°C (212 to 1,474°F)
• K Thermocouple: 100 to 1,205°C (212 to 2,201°F)
• S Thermocouple: 500 to 1,711°C (932 to 3,112°F)
• J Thermocouple: 100 to 754°C (212 to 1,389°F)
• R Thermocouple: 500 to 1,720°C (932 to 3,128°F)

At actual temperatures of -100°C (-148°F) or less, nuisance
alarms may occur.
Accuracy for trip points above 100°C (212°F):
• For part numbers starting with “TLME,” ± 5% of trip
point.
• For part numbers starting with “TLMC,” see below.
