Description Order Placing&Customized Production Typical Installation Example On-site installation example
The input level transmitter produced by Trumsense Precision Technology uses 1Cr18Ni9Ti stainless steel structure, and the silicon piezoresistive isolation membrane oil-filled core is sealed as a signal measuring element in a stainless steel housing, forming an integrated structure and standardized signal entity. The cable is hermetically connected to the shell. The air duct in the cable allows the back pressure cavity of the sensor to communicate with the atmosphere to ensure the accuracy of the measurement. It can be used for a long time in a liquid compatible with the structural material of the transmitter. It's convenient.

Based on the principle that the measured static pressure of the liquid is proportional to the height of the liquid, uses an isolated diffusion silicon sensitive element or a ceramic capacitor pressure sensitive sensor to convert the static pressure into an electrical signal Then, after temperature compensation and linear correction, it is converted into a standard electrical signal, which is generally suitable for liquid level measurement of various media in systems and industries such as petrochemical, metallurgy, power, pharmaceutical, water supply and drainage, environmental protection and other industries.

Product Elite Features:
►Small size, light weight, good long-term stability,
►The cable connection is resistant to water, oil and abrasion, flexible to use;
►Multiple pressure ranges and signal outputs;
►Non-polar two-wire current output;
►Available for lightning protection products;
►Available with level cable with reinforced ribs;
►Intrinsically safe, flameproof, CE certified.


Working Principle: (Using the principle of static pressure measurement:)
When the level transmitter is put into a certain depth in the liquid to be measured, the pressure formula on the sensor's liquid surface is: P = ρ .g.H + Po
In the formula:
P: the pressure on the transmitter facing the liquid surface ρ: the density of the measured liquid
g: local gravity acceleration
Po: atmospheric pressure on the liquid surface
H: Depth of the transmitter into the liquid
At the same time, the pressure of the liquid is introduced into the positive pressure cavity of the sensor through the gas-conducting stainless steel, and then the atmospheric pressure Po on the liquid surface is connected to the negative pressure cavity of the sensor to offset the Po on the back of the sensor, so that the pressure measured by the sensor is: ρ. gH, obviously, by measuring the pressure P, the liquid level depth can be obtained.

Ordering note:
  1. Media must compatible with wetted parts.
  2. There is two kinds of cable can be choose, one is common with gas tube, another is diesel oil &gasoline proof.
  3. If the transmitter need LCD or LED display that the power supply should no lower than 20VDC。
  4. To ensure the products can working reliable, we suggest that customer install lightning protection device and make sure products & power are earthed.
  5. If the range is lower than 0.5m,the accuracy would be ±1%
  6. Special requirement, such as strong shock, moment vibration, strong electromagnetism, radio frequency interference , please consult us.
Warranty:
Pressure transmitters have a limited one-year warranty to the original purchaser. Smart Sensor will replace or repair defective products free of charge. This warranty does not apply to any units have been modified, misused,  neglected .

 
►This input type liquid level transmitter has an isolation diaphragm in the pressure inlet. Do not touch it with foreign objects.
►For electrical connection, please strictly follow the wiring method. Misconnection will cause damage to the amplifier circuit.
►For submerged level transmitter installation, do not use wires to lift heavy objects other than the product.
►The probe is dredged regularly to avoid blocking the inlet.



Basic Wiring For This Lqiudi Level Transducer:


Typical Installation Example:




►The wire is a special waterproof wire. It should be free from wear, puncture and scratches during installation and use. If the above problems exist on the site, the conductor should be protected.
