Profile
LTS quartz tube level transmitter adopts side mounting through a bypass pipe or top mounting. The transmitter contains quartz tube plus stainless protective sleeve, level switch, level transmitter, etc..
Side mounted magnetic bundle unit through a bypass pipe is placed inside of the floating ball, while top mounted magnetic bundle unit is connected with the floating ball. When the floating ball moves over liquid level, the magnetic bundle unit shall move along a level relay made up of a serial of magnetic module. Under the action of the magnetic unit, the magnetic module inside the level relay shall make a corresponding action, output a changed resistor signal, and then transfer the signal into a current output signal of 4~20mA. Meanwhile, the level can be observed directly through the quartz tube, and a magnetic switch shall conduct a related action at the corresponding point, making alarming action and control output.
The magnetic unit of the floating ball adopts a special magnetic group, which can still provide the required magnetic force for normal working of the transmitter even if used for a long period. Meanwhile, when the floating ball moves along a guide rod, the stronger linear magnetic field derived from the magnetic bundle unit of the floating ball, shall attract magnetic induction modules in the sensor one by one, thereby improving the accuracy rating and reducing the deviation of the transmitter.
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.
Profile
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.

performance is stable and reliable.
Profile:
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.
LTJ uses split installing, and connect by flange. The transmitter part with aluminum alloy shell is sealed fastening. The shell specially adds the high molecular sieve stomata, it is breathable but impermeable, it can prevent condensation and protect the transmitter. The airway cable connection would make sure the sensors is keeping fair with the atmospheric pressure. It is suitable for big range measurement.
We provide two types of probes for you to choose. The transmitter part transforms signal from sensors into corresponding light pulse signal, then exports it by fiber.
