A pressure safety valve (PSV) protects pressure vessels and piping systems from excessive internal pressure. When a system reaches a predetermined pressure the PSV opens, a portion of the media discharges, and the pressure inside drops to a safe limit. Once the pressure reaches the valve’s reseating set point, the valve closes. …
Why Digital Manometer Accuracy Matters
In industries where precise pressure measurement is critical, digital manometers have become a standard tool. As demand for tighter tolerances grows, understanding the accuracy, resolution, and calibration requirements of these instruments ensures reliable performance in the field. Digital manometer accuracy matters because small measurement errors can lead to big problems – from inefficiency and poor performance to regulatory violations and safety hazards. At JM Test Systems,…
What is Traceability?
Traceability plays a critical role in modern supply chains, regulatory compliance, and quality assurance. At its core, traceability refers to the ability to track and verify the history, location, and application of an item through recorded identification. Organizations use traceability to enhance transparency, improve efficiency, and ensure accountability across various sectors, including manufacturing, food production, healthcare, and information technology. The Purpose of Traceability Traceability enables companies to monitor the flow of products and components from origin…
BSPT vs NPT vs BSPP: Which Thread Standard Should You Use?
Pipe fitting selection for pressure systems requires a solid understanding of BSPT, NPT, and BSPP thread standards to create leak-free connections and maintain system integrity. NPT (National Pipe Thread) seals remain the most popular choice in pressure calibration systems across the U.S. and Canada. BSPP (British Standard Parallel Pipe) leads the market in the UK, Europe, Asia, Australia, New Zealand, and South Africa. Chinese and Japanese systems commonly use BSPT (British Standard Pipe Taper), though it’s rare…
How to Reduce Electromagnetic Interference (EMI) And Its Effects
Electronic devices malfunction when electromagnetic interference (EMI) disrupts their operation. Engineers and technicians in military, defense, communication, appliance, and aerospace industries need to know how to reduce EMI. EMI can cause problems ranging from minor glitches to complete system failures. Electromagnetic compatibility (EMC) is a vital part of electrical equipment’s ability to work properly in an electromagnetic environment. Both manufacturers and users consider this one of their biggest concerns. Most electronic devices must comply with EMI regulations like…
