ｉｎｓｅｒｔ the cylinder level transmitter

1. Product Introduction

The insertion cylinder level transmitter is an ｉｎｓｅｒｔ-type hydrostatic liquid level measuring instrument that directly inserts into the liquid through an extension rod and protective cylinder structure, enabling continuous acquisition and signal output of liquid level height. The product uses a high-precision diffusion silicon sensor combined with anti-clogging, anti-fluctuation, and anti-entanglement protective cartridge designs. It can operate stably in complex media such as sewage, sludge, river water, wastewater, and chemical liquids, unaffected by floating solids, sediments, or flow fluctuations, making it an ideal solution for liquid level measurement in pools, storage tanks, deep wells, and wastewater treatment scenarios.

2. Product Features

1. Insertion cylinder direct-mount design

   Directly inserted into the liquid interior, easy to install, no need for complex flange modifications, suitable for various types of open tanks, tanks, and water tanks.

2. Anti-blockage, anti-fluctuation, and interference resistance

   The protective cylinder effectively isolates liquid level fluctuations, floating debris, sediment, and fibers, making measurements more stable, preventing film clogging and tangling.

3. Suitable for harsh media

   Can measure sewage, wastewater, slurry, river water, rainwater, cooling circulating water, and weakly corrosive liquids.

4. High precision and long-term stability

   Industrial-grade sensors, high precision, minimal temperature drift, no drift during long-term use, and no need for frequent calibration.

5. Standard output of 4-20mA

   Two-wire wiring system with DC24V power supply, can be directly connected to PLC, control cabinet, digital display meter, and remote acquisition system.

6. High protection level

   Fully sealed structure, waterproof, moisture-proof, and soak-proof, suitable for long-term use outdoors, underground pools, and damp wells.

3. Working Principle

The insertion cylinder level transmitter is based on the principle of static pressure level measurement:

The pressure of the liquid column is proportional to the height of the liquid level.

The probe inserts into the cylinder and inserts into the liquid to detect the liquid pressure. The sensor converts the pressure into an electrical signal, which is processed and outputs a standard signal of 4-20mA, enabling real-time liquid level measurement and remote transmission.

The protective cylinder serves to stabilize liquid, prevent clogging, and resist interference, making measurements smoother and more accurate.
