Applications
The immersion sensor 40-14 is used in numerous industrial processes in which the concentration of a liquid is to be continuously monitored. Typical applications include:
Sulfuric acid and chlorine gas drying
In the production, processing, and recovery of sulfuric acid, the immersion sensor 40-14 enables continuous concentration monitoring directly in the process. Sulfuric acid concentration can also be monitored in real time during chlorine gas drying. Different sensor materials and special materials are available for corrosive process conditions, allowing the sensor design to be adapted to the medium, concentration, and temperature.
Gas scrubbers and exhaust gas treatment
In process and emergency gas scrubbers, the immersion sensor 40-14 can be used for continuous monitoring of the scrubbing solution. Typical measured media include alkalis or acids, for example.
Real-time concentration measurement provides transparency about the condition of the scrubbing liquid and can be used for demand-based replenishment dosing as well as for stabilizing the scrubbing process.
Carbon capture and amine scrubbing
In carbon capture processes and other gas scrubbing processes, LiquiSonic® can be used for continuous monitoring of scrubbing solutions such as amine or alkali solutions.
The inline measurement provides current concentration values without delays caused by manual sampling and thereby supports stable conditions in absorption and regeneration circuits.
Chlor-alkali electrolysis and brine purification
In the chlor-alkali industry, the immersion sensor 40-14 is used, among other things, to monitor brine and process solutions. Continuous concentration measurement allows changes in the process to be detected immediately. For particularly corrosive media, the sensor can, for example, be made with suitable special materials such as titanium.
Additional application areas
In addition to these applications, the immersion sensor 40-14 can be used in numerous other industrial processes. These include, among others:
• Starch measurement in the paper industry: continuous monitoring of starch concentration in sizing processes
• Cold rolling: monitoring the concentration of rolling oil-water emulsions
• Texturing and etching baths: concentration monitoring of acidic and alkaline process baths
• Titanium dioxide post-treatment: inline monitoring of TiO₂ suspensions
• Evaporators and concentrators: monitoring concentration changes during the concentration process
• Water glass: continuous monitoring of alkali silicate solutions
In addition, the sensor is suitable for numerous other acid, alkali, and process solutions. Whether a specific measurement task can be implemented with the immersion sensor 40-14 depends on the medium, concentration range, and process conditions.
Installation options
The immersion sensor 40-14 can be integrated directly into tanks or pipelines. Different process connections and installation lengths allow the sensor to be adapted to different system geometries and measuring points.
Process connection
As standard, the immersion sensor 40-14 is available with the following process connections:
• DN 50 flange
• ANSI 2"
Additional process connections are available on request.
Installation lengths
The standard installation length is 92 mm. The following installation lengths are optionally available:
• 150 mm
• 250 mm
• 500 mm
• 1000 mm
• 1500 mm
• 2000 mm
The required installation length depends on the geometry of the measuring point. Relevant factors include, for example, nozzle length, wall thickness, pipe or tank diameter, as well as the desired position of the sensor head in the medium.
The right sensor design for your measuring point
Medium, temperature, pressure, system geometry, and concentration range differ from process to process. Therefore, the immersion sensor 40-14 can be adapted to the respective application with different materials, process connections, and installation lengths.
Material options
The wetted parts of the immersion sensor 40-14 can be made in different materials. This allows the sensor to be adapted to the chemical and thermal requirements of the respective application. The immersion sensor 40-14 is available as standard in stainless steel or Hastelloy available. Optionally, materials such as titanium, tantalum, or zirconium as well as additional special materials on request are available.
Which material is suitable for an application depends in particular on the medium, concentration range, operating temperature, pressure, and other process conditions. SensoTech therefore matches the material selection individually to the respective measurement task.
