Robust Construction for Demanding Environments

Crafted from top-grade SS 304 with optional SS 316, these diaphragm sealed gauges are engineered to withstand harsh chemical, petrochemical, food, and pharmaceutical applications. Their polished finish and precision machined components ensure both durability and corrosion resistance, making them suitable for challenging process industry settings.

Reliable Measurement and Versatile Configuration

Equipped with a stainless steel Bourdon tube sensor and filling options (glycerin filled or dry), these gauges deliver high accuracy (1.6% FSD) pressure readings for both liquids and gases. Their 100 mm dial and shatterproof glass window provide clear visibility, while the mounting flexibility (bottom/back flanged) ensures convenient integration into various systems.

Safety, Compliance, and Operational Confidence

Protection class IP65 shields the gauges against dust and water ingress. Overload protection up to 130% of full scale defends the device from sudden pressure surges. Fully conforming to EN837-3 standards, users benefit from consistent reliability and international compliance in industrial-grade pressure monitoring.

FAQs of Diaphragm Sealed Gauges:

Q: How are Diaphragm Sealed Gauges typically installed in process industries?

A: These gauges feature a 1/2 NPT (male) threaded connection and can be mounted either bottom or back flanged. Accessories such as mounting clamps and rubber gaskets are included to ensure a secure and leak-free installation in a wide range of industrial setups.

Q: What is the operational temperature range for these gauges, and can they handle harsh environments?

A: The gauges are designed for operation between -20C and +65C, making them suitable for most industrial environments. Their SS 304 (or optional SS 316) construction and IP65 protection ensure resistance to corrosive substances, dust, and water exposure.

Q: When should I choose a glycerin filled gauge versus a dry gauge?

A: Glycerin filled gauges are recommended when there is high vibration or pulsation in the process, as the fluid dampens needle movement and extends gauge life. Dry gauges are suitable for stable, low-vibration environments.

Q: Where are these diaphragm gauges commonly used?

A: These gauges are extensively used in chemical, petrochemical, food, pharmaceutical, paper, and pulp process industries, where precise and sanitary pressure measurement is essential for fluid and gas systems.

Q: What benefits do the optional diaphragm wetted parts (SS 316, Hastelloy, or Monel) offer?

A: Selecting optional wetted parts like SS 316, Hastelloy, or Monel enhances compatibility with aggressive or corrosive process media, providing improved longevity and reliability in specialized industrial applications.

Q: How does the gauge protect against overload and sudden pressure spikes?

A: Each gauge is equipped with overload protection up to 130% of full scale deflection, safeguarding the internal mechanism against potential damage from pressure surges.

Q: What compliance and standards do these gauges fulfill?

A: The gauges fully conform to EN837-3 standards, ensuring consistent measurement accuracy and reliability required in international industrial operations.
