Rubber

Dynatrol® Bulk Solids Level Detectors provide accurate point level detection for carbon black, rubber granules, pellets or powders. Dynatrol® Density Systems and Viscosity Systems are designed to measure density or viscosity at process conditions of latex, various rubber coatings or chemicals.

Bulk Solids Level Measurement

The CL10-DJ series of level switches are used to measure high-, intermediate-, or low-level detection of bulk solids. Applications for the Rubber Industry may include:

  • Carbon Black
  • Rubber Granules
  • Rubber Pellets
  • Rubber Powder

Viscosity Measurement

The Dynatrol® CL10-DV series Viscosity Probes and Series 3000 Viscosity Digital Converter are used to measure the viscosity of:

  • Adhesive Rubber Coating
  • Latex
  • Conformal Coatings

The Series 3000 digital converter can also process temperature. If the data is available the temperature can be used to either compensate for changes in temperature or correct to a reference temperature.

Density Measurement

The Dynatrol® CL10-HY Density Cell and Series 2000 Density Digital Converter can be used at process conditions to measure density, specific gravity, percent solids, or percent concentration of

  • Adhesive Rubber Coating
  • Conformal Coatings with Solvent
  • Latex
  • Rubber Chemicals
  • Slab Dip

Ammonium Hydroxide

Dynatrol® Density Measurement Systems are used extensively for measurement and control of density, specific gravity, or percent concentration with Ammonia solution, also known as ammonium hydroxide, ammonia water, ammonical liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or simply ammonia.

  • Eliminate multiple hand sampling when mixing
  • Real time percent concentration measurements of ammonium hydroxide with no effects from pressure changes or pipe vibration
  • Virtually no maintenance costs

Automation Products, Inc. was approached by a chemical company to devise a solution for online measurement of an ammonia solution. The process is describer below.

Issue

The chemical company needed online measurements while mixing anhydrous ammonia with water. Their pressurized ammonia was bubbled into a mixing tank with ultra pure water, and a sample stream was constantly pumped from the bottom of the tank to give a real time reading of percent concentration for aqueous ammonia.

Resolution

The chemical company chose a Dynatrol® Density System to solve their problem. The Dynatrol® Density Meter has the Temperature vs. Density vs. Percent concentration curves programmed into the Series 2000 Digital Density Converter. The density meter provides 4-20 mA signals to the chemical company’s control room for percent concentration and temperature of the ammonia and water solution. Since the Dynatrol® Density Meter outputs percent concentration, there was no need to program a complicated set of algorithms into the DCS control system to calculate percent concentration from density.

After months of comparing hand sample measurements to the measurements of the Dynatrol® Density Meter, the company found that the Dynatrol® Density Meter correlated directly to the hand measurements. The company now uses the Dynatrol® Density System in the control of the mixing process. This eliminates the bi-hourly hand sampling that technicians would have to perform.
