	LF 24 is a temperature sensor and transmitter that has been	Protecting standard		IP 65
	designed for mounting inside air ducts. The sensing coil	Mounting		Directly in the air duct using the
	consists of a PT 100 resistor capable of measuring
				flange provided.
	temperatures over its entire length of 3.6 m.
		NOTE: Distribute the sensing coil evenly across the whole
	The sensor then calculates the average temperature and
			diameter of the air duct to ensure temperature is
	converts this into a proportional output signal. This facility
			measured accurately.
	makes the LF 24 particularly suitable for use in air ducts
	where different layers so air may have different temperature,
	for example in mixing chambers or next to heating units.
