In CNC machining, cutting fluids and emulsions are the core media for machine tool operations. The stability of these liquids directly affects machining precision and workpiece quality, while also impacting consumable costs and production efficiency. However, most workshops face the same challenge: the liquid contains iron chips, oil, and suspended impurities that easily contaminate sensors, causing concentration readings to drift or become inaccurate. Frequent manual disassembly for cleaning is time-consuming, labor-intensive, and still fails to provide real-time concentration control.
To tackle the harsh conditions of machine tool tanks, a specially designed insert-type online concentration transmitter with pneumatic cleaning has been developed for the machining industry. It addresses the pain points of liquid monitoring and delivers 24/7 unmanned, high-precision measurement.
This concentration transmitter is tailored for the machining industry, fitting the production environments of CNC lathes, milling machines, grinders, and machining centers. It is compatible with both independent machine tool tanks and centralized workshop tanks.
The device uses a direct immersion installation method, requiring no modification of the tank structure. It can be fixed directly to the tank sidewall or top, with the sensor probe vertically immersed in the monitoring zone. Installation is simple, disassembly is convenient, and it adapts to tanks of all sizes, maximizing compatibility.
The transmitter measures the liquid’s refractive index and automatically calculates the corresponding concentration. Data is displayed locally in real time and output as a standard analog signal, enabling seamless integration with PLCs, industrial control screens, or workshop management systems. This allows for remote data upload and makes liquid concentration visualized and digital, eliminating rough manual sampling and estimation.
Heavy oil, abundant iron chips, and suspended impurities are the biggest threats to sensors. Fouling, residue, or coating on the probe directly causes data drift and failure, seriously affecting production quality.
To address this, the device integrates a pneumatic automatic cleaning system. By connecting to standard workshop compressed air, it supports custom-timed automatic blow-down:
✅ High-pressure air jets clean the sensor surface, quickly removing oil sludge, iron chips, and floating films.
✅ Fully automated cleaning requires no manual disassembly or wiping.
✅ Keeps the probe consistently clean, maintains detection accuracy, and ensures stable, reliable data. This significantly reduces maintenance frequency and labor costs, perfectly supporting continuous production workflows.
Four Key Benefits for Cost Reduction and Efficiency Improvement:
NO.1 Stable Machining Accuracy & Product Quality
Real-time monitoring of liquid concentration provides automatic alerts for deviations, prompting timely adjustments to maintain optimal fluid ratios and prevent defects, burrs, or excessive wear.
NO.2 Reduced Consumable Costs & Waste
Precise control over fluid usage slows degradation and aging, extends the life of cutting and grinding fluids, reduces waste replacement frequency, and significantly lowers consumable expenses, helping to compress overall production costs.
NO.3 Strong Resistance to Harsh Environments
Optimized for machine shop conditions with heavy vibration, oil, and impurities. The device is vibration-resistant, interference-resistant, and the corrosion-resistant probe adapts to complex fluids for long-term stable operation.
NO.4 Intelligent Monitoring & Workshop Automation
Data is uploaded in real time to cloud and control systems, enabling unmanned, intelligent, and visualized monitoring of tank fluid concentration, aligning with modern factory automation and digital upgrade needs.
In the era of smart manufacturing and cost-efficient production, rough manual control of liquid concentration is outdated. This insert-type online concentration transmitter with pneumatic cleaning solves machine tool tank monitoring challenges with precise measurement, automatic cleaning, and low maintenance. It enables factories to achieve refined production management. For stable control of machining fluid concentration, reduced maintenance costs, and upgraded intelligent workshop management, this device is the ideal solution!
