Semitec 103AT-11 IP67 Temperature Sensors
Semitec 103AT-11 NTC thermistor sensors are TPE plastic-encapsulated sensors offering waterproof protection for a wide range of temperature sensing applications. The small sensor tip is moulded in the same TPE material as the insulation on the lead-wires to help ensure IP67 integrity.
The Semitec AT-2 thermistors used in the AT-11 sensors ensure accurate temperature sensing or control to within ±0.3⁰C (at 25°C) and are better than ±0.5°C accurate over the range 0°C to 45°C. Thus they can be replaced with no adjustment or calibration required between the control circuit and the sensor if necessary.
The AT-11 offers an excellent, highly accurate, low-cost sensor for general temperature sensing applications such as refrigeration control, heat pumps and underfloor heating. The 103AT-11 version specifically has become an industry standard within the digital electronic thermostat industry.
