Sanitary industries, such as biotechnical, pharmaceutical, cosmetics, and food and beverage, are highly regulated to ensure certain processes comply with extremely strict hygienic requirements. To support operations and ensure product quality, measuring instruments in sanitary applications must provide accurate, reliable data — despite harsh process conditions.

Mechanical rotary power given from a motor must be driven by an appropriate amount of electrical power provided by the drive. Rotary power is provided for by the electrical input power and the rotary power cannot exceed the electrical. Therefore, it is important to verify the power throughout the system from power supply all the way to the motor or gearbox output shaft.

In Watlow catalogs, brochures and web pages there is a category of controllers listed as “Limits and Alarms”. It is not always clear to everyone when to use these controllers or which type of controller to use. This document is an attempt to clear up some of these issues.

Occasionally questions come up with regard to calibration of Watlow controllers. This paper will attempt to address some of the more common questions on this subject. Many people want to jump in right away and begin performing a calibration procedure before verification. Before you would attempt to calibrate a Watlow controller, verify that the controller is in need of calibration. If you verify that readings of the controller first, you may not have to go through the more involved process of changing the calibration settings.

Digital pathology is a rapidly growing segment of invitro-diagnostics with the potential to streamline the overall pathology process for the benefit of both doctors and patients. This relatively new market segment requires motion systems that support both high quality and high speed imaging. In addition, the scanners are dispersed globally, which drives the demand for extremely high reliability. Lastly, as with all diagnostic instruments, laboratory space is at a premium, so minimizing the overall footprint is critical.

Almost everyone knows someone whose life has been touched by heart disease or cancer—the two leading causes of death in the United States. Today, researchers are using DNA sequencing to better understand the genetic links we have with diseases and how it can influence the course of treatment. We are standing on the edge of the personalized medicine healthcare revolution, which will be fueled by the widespread adoption of DNA sequencing as a diagnostic tool.

The purpose of a filter is to remove contaminants from a fluid stream either completely, or at least down to a given rating or specification. Filters are used to help control contaminants and are rated according to their ability to remove these contaminants from a liquid, gas or air stream. There are different methods in which the performance of filters are specified.

Answer a number of key questions to identify the most appropriate choice
At process plants, a significant percentage of measurement devices aren’t correctly matched to their application, leading to decreased quality and consistency of the operation. Often, the source of this problem is the assumption that one type of level measurement sensor suits multiple applications.

There are two strategies for reducing control valve noise:
1. Source control, that is doing something to the valve to make it less noisy, and
2. Path control, that is doing something to prevent the noise from reaching the people who would be bothered by it.
