FAQ's of HEAVY DUTY GEMTECH Differential Pressure Gauges:
Q: How does the GEMTECH Differential Pressure Gauge operate for industrial gas measurements?
A: The GEMTECH Differential Pressure Gauge uses an analog display to measure the pressure difference between two points in a gas system. By connecting high and low pressure taps to the respective lines, it provides real-time, accurate pressure readings essential for monitoring various industrial processes.
Q: What accuracy can be expected from the gauge across different pressure ranges?
A: Accuracy varies according to the pressure range selected: 2% of full scale for standard ranges, 3% for specific lower ranges (such as -100PA, -125PA), and 4% for the lowest ranges (like -60PA). These figures are valid at 70F (21.1C), ensuring reliability for diverse measurement applications.
Q: When should I use this gauge in my industrial setup?
A: Install this gauge when you need to monitor or control differential gas pressure within process systems, such as filtration, ventilation, or pressure balancing in plants like pharmaceuticals, cement, or power generation. It helps maintain operational safety and system efficiency.
Q: Where is the GEMTECH gauge typically mounted and how is it installed?
A: This gauge is back-mounted and features 1/8" female NPT dual taps on both the side and the back, accommodating various installation preferences. Position the gauge at easily accessible points within the pipeline or equipment for convenient monitoring and maintenance.
Q: What process media is the gauge suitable for measuring?
A: The GEMTECH gauge is designed to measure the pressure of gases only. It's not intended for use with liquids or corrosive chemicals, making it a dependable choice for gas-based systems across multiple industries.
Q: What are the key benefits of using this differential pressure gauge?
A: Key advantages include highly accurate, repeatable readings, a tough metal alloy body for enhanced durability, compatibility with multiple pressure units, and an easy-to-read analog dial. These features improve safety, process control, and maintenance scheduling in critical environments.
