│Basic Information │

The ABB 1HSB495663-3 1233-4270CNTHB is a heavy-duty industrial gas density gauge specifically engineered to monitor Sulfur Hexafluoride (SF6) gas within high-voltage electrical insulation systems. Operating on a hermetically sealed, temperature-compensated mechanical layout, this gauge tracks real-time gas density instead of raw pressure, ensuring ambient outdoor temperature drops do not trigger false leakage alarms. The instrument features a local analog dial for manual on-site inspections and integrates multiple micro-switch electrical contacts to automatically alert substation control systems of low-pressure thresholds or lock out breaker operations if the gas volume falls below critical safety tolerances.

│Details│

Nominal Gauge Case Diameter: 100 mm (approx. 4.0 inches)

Electrical Contact Configuration: Up to 3 independent micro-switches

Micro-switch Relay Contact Rating: 250 VAC / VDC (at up to 10W / 10VA capacity)

Process Interconnection Connection: Rear or bottom threaded adapter

Operating Ambient Temperature Range: -40 °C to +60 °F (-40 °F to +140 °F)

Internal Gas Leakage Permeability Rating: ≤ 1 × 10⁻⁸ mbar · l/s

│Applications│

➟ High-Voltage Circuit Breaker Monitoring: Mounts directly onto live high-voltage tank circuit breakers to continuously monitor SF6 gas insulating volume and verify arc-quenching capability remains intact.

➟ Substation Automated Safety Interlocking: Rewired directly to main control room alarm relays to send instantaneous "Low Gas Volume Warning" or "Critical Breaker Operation Lockout" signals during active line faults.

➟ Gas-Insulated Busducts (GIB) Inspections: Installed along lengthy cross-country outdoor gas-insulated distribution pipes to monitor physical gas integrity under variable solar heating loads.

Step 1 Email confirmation

After checking out or requesting a quote, you will receive an email confirming that we have received your order. Your quote will be accepted or your web order will be placed.

Step 2 Dedicated customer service rep

One of our customer service reps will be in touch to verify your part(s) and confirm your shipping details.

There's also a principle running through everything amikon does that doesn't show up on a spec sheet: if a customer can't find their part anywhere else, the team will track it down. No dead ends. That's a promise, not a marketing line.

If your line is down or you're trying to source a part that everyone else has given up on, the story continues. So does the search.
