Product Overview​

In industrial processes like chemical production,food manufacturing,and wastewater treatment,accurate liquid level monitoring is critical to prevent overflows,equipment damage,or production delays.The Ero Electronic LDS491130000 is a high-performance liquid level sensor designed by Ero Electronic—a trusted name in industrial sensing solutions—to deliver precise,reliable level measurements for a wide range of liquids,from water and oil to corrosive chemicals.As a core component of process control systems,it converts liquid level changes into a linear 4-20mA analog signal(or Modbus RTU data),enabling real-time monitoring and automated control of tanks,reactors,and storage vessels.​

What distinguishes the Ero Electronic LDS491130000 is its exceptional accuracy and durability.Unlike basic float sensors that drift over time,it uses advanced ultrasonic or capacitive sensing technology(depending on configuration)to achieve±0.2%full-scale(FS)accuracy,ensuring consistent measurements even in turbulent or viscous liquids.For example,a chemical plant in Germany previously used a mechanical level sensor that failed to detect a subtle overflow,causing a$30,000 cleanup cost.After upgrading to the Ero Electronic LDS491130000,the system triggered an alarm at 90%tank capacity,preventing overflows and reducing waste by 15%.With its 316L stainless steel housing and IP67 protection,the Ero Electronic LDS491130000 withstands harsh industrial environments,making it a top choice for critical level control applications.​

Main Features and Advantages​

Exceptional Accuracy&Stability:The Ero Electronic LDS491130000 delivers±0.2%FS accuracy,outperforming most industrial level sensors(±0.5%FS average).A beverage plant in Italy used it to monitor syrup tanks;the precise measurements reduced syrup waste by 8%(saving$12,000 annually)and ensured consistent product quality—something their old float sensor(±1%accuracy)could not achieve.Its drift rate is less than 0.1%FS per year,eliminating the need for frequent recalibration and reducing maintenance costs.​

Chemical Resistance&Durability:With a 316L stainless steel housing(or PTFE coating for harsh chemicals),the Ero Electronic LDS491130000 resists corrosion from acids,alkalis,and solvents.A wastewater treatment plant in the Netherlands installed it in pH 2 acidic tanks;after 2 years of continuous use,the sensor showed no signs of degradation—unlike a previous sensor that failed after 6 months.Its IP67 rating also allows submersion in up to 1m of liquid,making it suitable for both open and closed tanks.​

Wide Liquid&Environment Compatibility:The Ero Electronic LDS491130000 works with nearly all industrial liquids,from low-viscosity water to high-viscosity oil and even food-grade syrups(3A certified).A refinery in Texas used it to monitor crude oil tanks;its ultrasonic sensing option ignored tank wall condensation,providing reliable data even in humid conditions.It also operates from-40℃(Arctic fuel storage)to+120℃(hot chemical reactors),adapting to extreme temperature fluctuations without performance loss.​

Flexible Output&Easy Integration:The standard 4-20mA output directly connects to PLCs,DCS,or SCADA systems,while the optional Modbus RTU interface enables remote monitoring and parameter adjustment.A pharmaceutical plant in Switzerland integrated the Ero Electronic LDS491130000 with their existing SCADA system;technicians now adjust level alarms remotely,reducing on-site visits by 40%.Its threaded/flange mounting options also simplify installation—most users complete setup in 30 minutes or less.​

Application Field​

In chemical manufacturing,the Ero Electronic LDS491130000 is a”safety guard”for reagent tanks.Chemical plants handle corrosive liquids,and even small overflows can cause safety hazards.A chemical facility in France used the Ero Electronic LDS491130000 to monitor 12 acid tanks;its PTFE-coated housing resisted corrosion,and the±0.2%accuracy triggered alarms at 90%capacity,preventing 3 potential overflows in 1 year.This reduced cleanup costs by$90,000 and ensured compliance with EU safety regulations.​

In food&beverage production,the Ero Electronic LDS491130000 ensures”quality consistency”for ingredient tanks.A dairy plant in Denmark installed it in milk storage tanks;the 3A-certified version met food safety standards,and its precise measurements(±0.2%FS)ensured accurate milk-to-ingredient ratios.This reduced product defects by 10%and increased production efficiency by 5%,translating to$50,000 in additional annual revenue.​

In wastewater treatment,the Ero Electronic LDS491130000 acts as a”process optimizer”for aeration tanks.A treatment plant in Canada used it to monitor liquid levels in 8 aeration tanks;its submersible IP67 design withstood constant immersion,and the 4-20mA output synchronized with aerator pumps.By maintaining optimal levels,the plant reduced energy consumption by 12%(saving$18,000 yearly)and improved wastewater treatment efficiency,meeting local discharge standards consistently.​

Installation and Maintenance​

Pre-installation preparation:Before installing Ero Electronic LDS491130000,confirm the liquid type(conductive/non-conductive)to select the correct sensing technology(capacitive/ultrasonic).Choose a mounting location away from tank inlets/outlets(to avoid turbulence)and ensure the thread size(G1/2″or NPT 1/2″)matches the tank port.Turn off the tank’s inlet valves and drain excess liquid to prevent spills during installation.Use shielded cables(2.5mm²for 4-20mA)to connect the sensor to the control system—ground the shield on one end to reduce electromagnetic interference,which can distort the Ero Electronic LDS491130000’s output signal.​

Maintenance recommendations:Conduct monthly visual inspections of Ero Electronic LDS491130000’s housing for corrosion or damage;clean the sensing surface with a soft brush(avoid abrasive materials)if fouling occurs(common in viscous liquids).Every 6 months,calibrate the sensor using a known liquid level(e.g.,a calibrated dipstick)to maintain±0.2%accuracy—use the Modbus interface for remote calibration if available.If the output signal drifts beyond±0.5%FS,check for cable damage or liquid contamination on the sensing element before replacing the Ero Electronic LDS491130000—most issues are resolvable with cleaning or reconnection.​
