Measuring the density.
In the pharmaceutical process reactors, the recipe is often controlled by a 2-phase Foxboro densitometer. Product density determines the end of the process. This reading should be highly reliable and should not be affected by air bubbles in the recirculation line.
Foxboro conductivity sensor
Cleaning by conductivity.
When cleaning pharmaceutical equipment, a Foxboro conductivity sensor is used to determine the cleaning cycles using caustic, acid and rinsing with hot water. The concentration of the chemicals and the rinsing water quality is controlled by the conductivity sensor. This provides savings of chemicals and water consumption while reducing rinsing time.
OleumTech wireless systems
Measurement of reactors.
The reactors are often moved from one room to another and cleaning of the equipment becomes complicated to meet the sanitary 3A approval. Wireless measurement systems are used to move the reactors without having to wire them in the new room. Moreover, there is no more connector and it’s easier to clean these reactors and to respect the sanitary 3A approval.
Action Instruments flexible temperature sensor
In pharmaceutical processes, the temperature reading is often done with an RTD installed outside of the piping. It is a flexible temperature sensor mounted with a tri-clamp 3A flange. These probes are then routed to the Action temperature transducers placed in a control panel. This avoids contact when washing the equipment.
Hardy & LSI anti-vibration system
Drug weight measurement.
Quality control during the filling of the bottles is done with weight measurement. Hardy, with his anti-vibration system, allows you to read with great accuracy the weight of the bottles and thus increases the speed of the weighing. One can thus validate the presence of the amount inserted into the bottle. The same goes for monitoring the packing of the bottles. Hardy, by measuring the weight, validates the number of bottles in each of the boxes. The information can be measured and transmitted to the control room by wireless LSI modules.
Monitoring the manufacture of the drug.
During the manufacture of the drug, the information must be recorded in order to trace the history of the drug, as specified by pharmaceutical regulations. The Chessell recorders are specially approved for this type of application. The information is stored in the memory of the unit and is also encrypted. A software provided only by Chessell decodes this information.
Dimetix & Optech lasers
Some pharmaceutical processes do not allow the inside installation of a probe to read the level. It is then possible thru a glass window on top of the tank to read the level with a laser. This technology does not require cleaning and is not affected by the internal pressure or the presence of explosive gases in the tank.
Intrinsic MTL safety barrier
Alcohol is very often used in pharmaceutical processes. This product is highly flammable. That is why we must protect each of the instruments with an intrinsic MTL safety barrier to avoid potential explosions.
