LTJ21 guide rod insert type level transmitter
Characteristics: Accurate and reliable level measurement. High accuracy up to 0.1. Flexibly installation. The zero point and full range can be adjusted. Suitable for the flowing and whipping liquid. Restrict to the length of guide rod, the measurement range is narrow: 0.5–4m.
Profile
LTJ21 guide rod insert type level transmitter adopts diffusion silicon or dry ceramic capacitor as measurement unit. In process of measurement, diaphragm of probe, under action of level pressure, shall change its capacitance or resistance. The concise voltage signal shall be output after capacitance or resistance signal is enlarged by microcircuit. Finally, the signal shall be transferred into a corresponding standard current signal output of 4~20mA.
The measurement parts and transmission parts of LTJ21 are connected by the rigidity of the stainless steel
guides, it is suitable for the environment of flow rate liquid and swinging liquid. It is easy to install. But the
guide rod’s length is limited, so the measuring range is smaller. The sensors could select ceramic capacitor diaphragm,
the measurement is accurate and reliable, its accuracy class can up to 0.1.

Characteristics: It is polished, and the appearance is beautiful.
The magnetic unit material is NdFeB which is used in Space station, the magnetic structure is special,
so the magnetic beam is centered in the line plan, the strength can be sustained.
The output contact is with magnetic memory. It is suitable for measuring the liquid level which is in non-pressure
applications.
Profile: The body of the BNA11 single–pass magnetic flap level gauge and the measuring media are connected by a
bypass tube, to make the media level in the body is consistence to the external media. At the top of the level
gauge body there is opening a cited pressure hole which is used to connect with atmospheric, which is suitable
for atmospheric pressure environment. In the bottom of the body, there is adding a bottom flange, to easy
maintain (open the bottom flange and clean the precipitate).

LTJ11 integrated input type level transmitter 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 measurement parts and transmission parts are integrated, compact structure, it’s easy for installation. The sensor and transmitter are sealled in the probe, and the case of the probe is a stainless steel sealing structure, the protection class can up to IP68.
Characteristics: It can work in different and extensive pressure. Good anti-jamming ability. More precise with permanent magnet. The sensor parts adopt the designation of integrated module: stable and reliable. High-resolution: as high as 5mm.

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.
