Level transmitters are used to measure and control liquid level measurement and control in industrial fields, urban water supply and wastewater treatment, petroleum, chemical industry, power plants, hydrological monitoring, reservoirs, dams, and hydropower construction. Level transmitters are input type, straight rod type, flange type, thread type, inductive type, screw-in type, float ball type structure design, anti-blocking type design, simple installation, easy to use, strong interchangeability The high-quality sensor has high sensitivity and fast response, accurately reflecting the subtle changes in the flow or static liquid level, and has high measurement accuracy. The product features advanced design principles, complete specifications, and easy installation and use. Level transmitters are classified and function as follows:
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.
