Level Transmitter Classification and Function

Silicon Piezoresistive

The silicon piezoresistive level transmitter is based on the liquid level sensor and measures the hydrostatic pressure proportional to the depth of the liquid level and converts it into a standard current and voltage signal output through an amplifier circuit to establish an output electrical signal and liquid. The bit depth of the linear contrast relationship, to achieve the measurement of the depth of the liquid. In the structure, the waterproof conductor is sealed and connected with the stainless steel shell. The vent pipe communicates with the outside in the cable and the inner structure is protected against condensation. With good stability and reliability, it is widely used in the measurement and control of water levels in the fields of environmental protection, water conservancy, power plants, urban water supply and drainage, and hydrology exploration.

Skid-mounted

The product can directly infiltrate the bottom of the liquid, measure the height from the sensor at the end to the surface of the liquid level, is easy to install, and has high reliability. It is suitable for open level containers or liquid level measurement that needs to be inserted and installed.

Lightning protection

The lightning level transmitter will encapsulate the OEM oil-filled core in a stainless steel housing. The front-end protective cap functions as a protective sensor diaphragm. It also allows the fluid to smoothly contact the diaphragm. The waterproof conductor is sealed and connected to the housing. The trachea passes through the internal structure of the cable and the atmosphere to prevent condensation. A three-level lightning protection module is designed on the internal circuit to effectively prevent the lightning damage.

Input type

The input type level transmitter is based on the principle that the measured hydrostatic pressure is directly proportional to the height of the liquid. The piezoresistive effect of diffusion silicon or a ceramic sensitive element is used to convert the static pressure into an electrical signal. After temperature compensation and linear correction. Convert to 4-20mADC standard current signal output. The sensor part of the input hydrostatic level transmitter can be directly put into the liquid, and the transmitter part can be fixed with a flange or a bracket, which is very convenient for installation and use. Its product features: good stability, high precision

The input level transmitter has power polarity reverse protection and overload current limit protection. Solid state structure, no moving parts, high reliability, long service life High precision measurement from water, oil to paste with high viscosity, without influence of bubbling, deposition, electrical properties of measured media, wide range of Temperature compensation.
