The analog dial is easy to read and built to withstand continuous use in harsh environments.
FAQ's of GEMTECH Differential Pressure Gauge - ENVIRO TECH INDUSTRIAL PRODUCTS:
Q: How does the GEMTECH Differential Pressure Gauge measure pressure?
A: The gauge measures the difference between two pressure points using its analog dial, providing direct readings in selected units such as MM WC, CM, KPA, INCH, or PSI. Dual high and low pressure taps at the side and back improve flexibility and accuracy for a range of industrial applications.
Q: What industries commonly use this pressure gauge?
A: Industries such as power plants, cement production, steel manufacturing, fertilizer processing, and textile facilities typically use this gauge due to its durable build, reliable accuracy, and compatibility with gas pressure measurement in complex systems.
Q: When should I opt for this analog differential pressure gauge?
A: You should choose this gauge when there is a need for robust, precise, and real-time pressure monitoring in environments where electronic or digital options may be less suitable due to harsh conditions or limited electronic infrastructure.
Q: Where can the GEMTECH gauge be installed?
A: The gauge can be securely mounted onto process panels or directly onto pipelines using its back mount and 1/8" NPT female thread connections. Its versatile taps allow installation in both new projects and as replacements in existing systems across different industries.
Q: What is the installation process for this gauge?
A: To install, simply select the appropriate pressure tap location (back or side), secure the gauge using the specified mounting method, and connect the process lines to the 1/8" NPT female threads. Ensure the connections are tight for leak-proof performance before placing the gauge in operation.
Q: How is the accuracy of the GEMTECH gauge ensured?
A: The gauge offers a standard accuracy of 2% of full scale, with high-accuracy (HA) models providing even tighter tolerances. For specific low-range models, the accuracy may vary as detailed in the technical specifications, making it reliable for critical applications.
