Superior Construction for Demanding Environments

The Series 900 gauges are engineered using stainless steel 304/316 for the case, with brass or stainless steel movement options. Their shatterproof glass and durable components shield them from harsh industrial settings, making them suitable for challenging conditions in chemical, petrochemical, and power plants.

Precision Measurement and Versatile Application

With Bourdon tube sensors (C-type or helical), these gauges provide precise analog readings with a scale range up to 1000 kg/cm and accuracy of 1% of FSD. They are versatile, supporting direct, flanged, or diaphragm sealed connections, and can measure liquid, gas, or vapour pressure reliably.

Customizable and Reliable Design

Available in bottom or back mounts and two sizes, the Series 900 gauges include optional accessories like overload stop and blow-out disc. Their polished stainless steel finish, neoprene/nitrile rubber seals, and aluminum dials provide longevity and easy readability. Various thread types and process connections accommodate specific user requirements.

FAQs of Process Gauges Series 900:

Q: How are Process Gauges Series 900 installed for different applications?

A: Process Gauges Series 900 can be installed using direct, flanged, or diaphragm sealed connections, accommodating both bottom and back mount types. They are adaptable to various process requirements, with 1/2 NPT threading standard and other thread sizes available on request.

Q: What benefits do stainless steel construction and shatterproof glass offer?

A: Stainless steel provides resistance to corrosion and ensures durability in harsh environments, while the shatterproof glass window protects the gauge from physical damage, maintaining clarity and operational safety in industrial settings.

Q: Where are these gauges commonly used?

A: Series 900 gauges are widely used in chemical plants, petrochemical facilities, power plants, oil and gas operations, and general industrial applications across India and around the world.

Q: When should I select a diaphragm sealed process connection?

A: Diaphragm sealed connections are recommended when measuring corrosive, viscous, or contaminated media. They protect the Bourdon tube and gauge internals, ensuring accurate readings and extended lifespan.

Q: What is the process for calibrating these pressure gauges?

A: All Series 900 gauges are precision calibrated during manufacturing to ensure an accuracy of 1% of full scale. For critical applications, calibration should be verified and adjusted periodically to maintain optimum measurement performance.

Q: How do I determine which size or mount type is suitable for my system?

A: Select the outer size (100 mm or 150 mm) and mount type (bottom or back) based on your equipments spatial constraints and the visibility required for readings. Both options provide clear analog displays for effective monitoring.

Q: What usage precautions should be followed for optimal performance?

A: To maintain accurate readings and product longevity, ensure ambient temperature remains between -20C and +60C, avoid mechanical overload, and periodically inspect seals and connections for leaks or wear, following manufacturer guidelines.
