Practical guidance for correct selection, installation & use of instruments

Quick Engineering Guide

Pressure Range

Always select 1.5–2× operating pressure to avoid fatigue and failure.

Vibration

Use glycerin-filled gauges to stabilize pointer movement.

Steam Use

Install a syphon to protect gauge from high temperature steam.

Corrosive Media

Use diaphragm seals to prevent damage and clogging.

Temperature Accuracy

Ensure proper immersion length for correct readings.

Pressure Gauge Selection

Range

Choose 1.5–2× working pressure for longer life.

Accuracy

Select based on application criticality and precision required.

Dial Size

Larger dial improves readability from distance.

Material

Select wetted parts based on media compatibility.

Application

Use liquid-filled gauges for pulsating conditions.

Safety

Blow-out back ensures safety in case of failure.

Temperature Gauge Selection

Types

Choose between bimetal, gas-filled or RTD based on need.

Stem Length

Incorrect immersion causes major measurement error.

Mounting

Select orientation for easy reading and access.

Thermowell

Protects sensor and allows removal without shutdown.

Accessories Guide

Syphon

  • Reduces temperature impact in steam applications.

Snubber

  • Dampens pressure spikes and pulsations.

Needle Valve

  • Allows isolation and controlled pressure entry.

Diaphragm Seal

  • Isolates instrument from harsh process media.

Capillary

  • Used for remote mounting away from process heat.

Thermowell

  • Provides mechanical protection for temperature sensors.

Diaphragm Seals

Purpose

Protects instruments from corrosion, clogging and extreme conditions.

Types

Available in threaded, flanged and sanitary designs.

Fill Fluid

Determines operating temperature limits and response.

Accuracy Impact

Incorrect selection can affect response time and readings.

Common Mistakes

Overpressure

  • Operating beyond range causes permanent damage to sensing element.

Temperature Overload

  • Excess heat affects accuracy and damages internal components.

Vibration

  • Continuous vibration loosens parts and disturbs calibration.

Pulsation

  • Pressure spikes cause pointer fluctuation and mechanical wear.

Corrosion

  • Wrong material selection leads to chemical attack and leakage.

Mechanical Shock / Fall

  • Impact damage can misalign internal mechanism or break parts.

Improper Mounting

  • Wrong installation causes stress and inaccurate readings.

Clogging / Blockage

  • Dirty or viscous media blocks pressure entry.

No Accessories

  • Missing syphon/snubber leads to premature failure.

Installation Tips

Mounting Location

Avoid high vibration and shock areas.

Connections

Use flexible connections where required.

Sealing

Ensure leak-proof installation using proper sealing.

Visibility

Install where readings can be easily monitored.

Maintenance & Calibration

Calibration

Regular calibration ensures accuracy over time.

Standards

Use NABL certified labs for reliable results.

Replacement

Replace gauges if accuracy deviates significantly.
