The only fixed gas detector where the transmitter lives inside the sensor.

Every other system on the market separates them. We don’t. That’s not a small difference - it’s a fundamentally better architecture.

Safeguard’s smart sensor carries the intelligence traditionally housed in the transmitter - creating a more connected, traceable, and intelligent gas detection architecture.

Foresight by Safeguard Analytics

Continuous monitoring of gas activity and sensor health across the site.

Gas readings tell you what is happening. Sensor behavior tells you whether you can trust the reading.

Foresight continuously monitors gas activity and sensor performance across the site, helping distinguish emerging leak conditions from abnormal sensor behavior and degradation.

Because the sensors and analytics platform are engineered together, Foresight can evaluate trends across the entire monitoring system - helping teams identify potential sensor issues earlier, reduce unnecessary maintenance, and prioritize service before reliability is compromised.

Continuous monitoring. Earlier insight. Smarter maintenance decisions.

Comparing platforms? See how Foresight compares to device apps and remote notification.

Three distributed systems. One platform.

Wired fixed detection, meshed POD-zone monitoring, and a combustion analyzer fleet. Foresight works across all three, and all three deploy into the same range of applications - so you can start anywhere and scale without replacing hardware or re-engineering communications.

Wired Fixed System

SA-220s Wired to an SCX

SA-220 fixed gas detectors wired back to an SCX control system and connected to Foresight and/or your customer SCADA. Local relays, Modbus RTU, and 4-20 mA output keep safety decisions independent of any network.

The Grid-Distributed monitoring

The Grid

Multiple 4DS-E PODs and a MET weather station, meshed to a Hub and reported through Foresight. Our sensor Pods combined with our meteorological pod feed continuous data to Foresight to correlate readings to where issues might be coming from.

Products: 4DS-E PODs, MET Station, Hub, Foresight
Portable or Fixed Fleet Management

Combustion Fleet Management

SA-PMSA portable and SA-FMSA fixed gas analyzers running as a fleet on Foresight. Every gas type monitored - O2, NOx, CO, CH4, C3H8, etc - becomes a ranked, explainable diagnosis instead of a raw reading, with data being captured.

Where facilities see the return

Modeled outcomes from predictive monitoring, smart sensor architecture, and site-wide leak correlation, based on typical deployment profiles.

Fixed Gas Sensors

Sensor Replacement Reduction

Replace sensors based on actual performance instead of fixed calendar intervals.

  • Fewer sensor replacements vs. 2-year replace cycles
  • Less calibration and bump-test labor
  • Longer sensor service life
  • Lower annual sensor and calibration cost per site
Site-Wide Leak Correlation

Uptime from Early Leak Detection

Detect and correlate leaks before they escalate into shutdowns or emergency response.

  • More production uptime
  • Unplanned downtime avoided annually
  • Earlier leak detection than monthly manual rounds
Natural Gas & Diesel Gas Combustion

Combustion Fleet Optimization

Tune exhaust emissions and fuel/air ratios across combustion units to cut downtime and operating cost.

  • Less unplanned downtime
  • Fewer forced outages
  • Lower fuel cost
  • Higher production output
