Selecting the Right Technology for High Temperature Applications

PROBLEM:
A pharmaceutical company was having a problem with using rotary paddle level control technology in an application where the process temperature was in excess of 300° F. The units were failing quicker than they expected. They needed to look at a different solution for their high level control.

EXPLANATION:
The company produces proprietary materials and ingredients used in the Pharmaceutical industry. Their process includes handling “ash” which is very fine and is produced at a point in the process where the material temperature is in the area of 350-375° F. The unit in question was mounted in a hopper that contains baghouse ash. The mounting orientation was from the side. While high temperature rotary units are available, the “ash” is so fine that it finds its way into the rotary units through the seal. This also seemed to impact the life of the rotary unit. The customer just wanted to get away from electromechanical units and they needed something that they were certain would operate reliably all the time.

SOLUTION:
Monitor recommended its TrueCap® Model MK2 state-of-the-art RF capacitance point level sensor. This unit, equipped with a 3/4 ” stainless steel process mounting connection is able to tolerate up to 400° F when the ambient air is at or below 122° F. In addition, the MK2 is extremely calibration stable, uses microcontroller technology and provides push-button calibration, automatic temperature compensation, a universal power supply, local indicating LED’s and automatic build-up immunity. Following the success of the 30-day trial period the company was so pleased with the performance of the TrueCap MK-2 that they immediately placed an order for another 2 units. The customer has said, “The units work great and they are very consistent. The MK-2 has more than met our expectation”. The customer further commented; “Working with monitor was a pleasant experience and their local representative went the extra mile to make sure we got what we needed for our application”.
