LTJ31 cable throw-in type liquid level transmitters use a dry ceramic capacitor sensor as measurement unit. Probe diaphragm shall be subject to level pressure, causing a corresponding elastic displacement in the process of measurement. According to the principle of level pressure in proportion to the distance between the two poles, a changing capacitance shall be detected by the transmitter, and then enlarged so that it can output a accurate voltage signal when passing through trimming circuit. Finally, the signal shall be converted to a corresponding standard current signal output with a range from 4mA to 20mA.
The transmitter uses two-wire wiring, which can be wired easily; Junction box is separated from probe, making it more suitable for on-site installation; the shell of sensor adopts stainless steel omniseal structure, which can attain a protection class up to IP68; the cable uses a water-proof gas guidance cable, capable of withstanding long-term immersion in water. Thereby, the transmitter is a liquid level measurement device featuring reasonable structure, economic and stable performance.

LTL series of transmitter use dry ceramic sensors as measuring unit. When the sensor is put into the measured liquid, the level will give a pressure on the surface of the sensor’s membrane. According to the proportion principle to the liquid pressure and liquid level, it will produce a corresponding elastic displacement. Because the dielectric and the area between two plate is constant, the capacitance and the distance between the two level is in proportion, so from substrate electrode and diaphragm electrode it can detects the changing capacitance. When the capacitance is enlarged by fine-tuning circuit, it can export an accurate voltage signal. Then the outputted voltage signal will be transformed into corresponding light pulse signal and exported.
