NTC12k Sensors

All-purpose temperature sensors

ETF is a range of temperature sensors designed for use in heating, ventilation and cooling systems. No one temperature sensor satisfactorially meets all needs. The requirements to be met must therefore be carefully considered. Please see our product sheet for a full description of the different sensors and their applications. All major parameters have been taken into consideration in the design of our ETF sensors, including: measured temperature, mechanical load, corrosion, erosion and required response time.

Calculation table

NTC sensor type: ETF-22/33/55/99

Sensor for temperature range -30 - +125°C.

Wide application range, commonly used for normal ambient temperatures.

Precision +/- 5% Ohms at 25°C, equal to +/- 1,2°C. RTemp at 25°C = 12 KOhm.

Sensorleads can be extended several hundreds meter without influence on the reading.
