What is a Dynamometer and How Does it Work?

A dynamometer, or "dyno" for short, is a device for measuring force, moment of force (torque), or power. For example, the power produced by an engine, motor or other rotating prime mover can be calculated by simultaneously measuring torque and rotational speed (rpm).

How To Meet UPS 797 & USP 800 Compliance Standards

 

Are You Compliant With USP 797 and USP 800 Standards?

Revised standards for USP General Chapter <797> for compounded sterile preparation (CSP) have been finalized and are active as of Nov 1, 2023. These revisions will also affect USP <800> where hazardous drug (HD) compounding is applicable. Both standards include environmental monitoring and management requirements that were not previously enforced and must be met to achieve accreditation through local and national governing bodies. Understanding the conditions and monitoring requirements is critical in ensuring compliance.

If you need help understanding the UPS <797> and USP <800> requirements and want to find compliant solutions, we would be happy to assist! Contact Setra today to talk with our product team and make sure that all of your spaces are compliant.

How to Convert mA to Voltage

Converting mA to voltage is common in HVAC when working with pressure transducers. Terminology to keep in mind includes:

  • 1 mA = 0.001 AMP (short for amperes)
  • Amps are referred to as CURRENT
  • Resistor values are in OHMS (Ω is the symbol for ohms)
  • VOLTAGE is the result of passing amps through a resistor

How to protect transducers from electromagnetic and radio-frequency interference

Design engineers have a lot to consider when selecting components for use in end-user products and equipment. Original Equipment Manufacturers (OEMs) that follow a strict Design for Manufacturing and Assembly (DFMA) methodology will have few, if any, problems with pressure transducers. However, OEMs that do not adhere to DFMA practices in their factory increase the likelihood of reoccurring issues, including transducer failure.

3 Overlooked Design Considerations When Choosing a Pressure Transducer

When first selecting a pressure transducer for a new project or piece of equipment, designers typically focus on key design parameters such as pressure range, electrical output, media compatibility and environmental conditions.  However, those parameters are not the only ones to consider when making a smart choice for an application. There are three design considerations that are often overlooked when selecting a pressure transducer: transfer medium (oil filled vs. non-oil filled), construction, and type of sensing technology.

What is Hysteresis?

Hysteresis Defined

According to Merriam-Webster, hysteresis is the “lagging of a physical effect on a body behind its cause (as behind changed forces and conditions)”. When outside forces act on an object, that object will either immediately spring back to its original state, or more likely, it will somehow change or exhibit properties from previous deformations.

What Are The Different Types of Pressure Tests for Engine Test Stands?

Did you know that companies spend hundreds of millions of dollars on research and development for off-highway vehicle engines? A portion of the R&D goes into developing specialized engine test stands to ensure that the engines are functioning properly.

Engine test stands are complex, engineered systems designed to measure, control and record parameters during the different engine manufacturing stages.

What is the difference between 17-4 and 316L stainless steel?

When selecting stainless steel for various applications, understanding the differences between 17-4 and 316L stainless steel is crucial. Both alloys offer unique properties tailored to specific needs.

Stainless steel (SS) comes in all shapes, sizes, and compositions. It’s an alloy comprised of several different elements such as iron, nickel, and chromium with superior corrosion resistance compared to its constituent parts. Different applications require different material properties. In fact, there are dozens of individual grades of stainless steel alone, each with a unique proportion of ingredients and application benefits. This article will focus on two types in particular: 17-4 and 316L stainless steel.

How To Stop Water Hammer

What is Water Hammer?

Water hammer is shock wave produced by the sudden stoppage or reduction of a fluid flow. This can cause sudden rises in pressure and damage instrumentation. In tank level measurement applications, high pressures can be generated by the sudden closure of a valve on an outlet line. Although it might seem to be a consistent flow, the water inside pipes tumbles as it moves through.
