Characteristics: Suitable for irregular and narrow gauge hatch. Accurate and reliable level measurement. High accuracy up to 0.1. Flexibly installation. The measuring range is very deep: as deep as 200m. The zero point and full range can be adjusted.
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.
