ANSI / ISA Classification of Corrosion
| Category | Severy | Copper | Silver |
|---|---|---|---|
| G1 | Mild | <300 Å | <200 Å |
| G2 | Moderate | <1,000 Å | <1,000 Å |
| G3 | Harsh | <2,000 Å | <2,000 Å |
| GX | Severe | >2,000 Å | >2,000 Å |
Equipment manufacturers (OEM) for mission critical infrastructure will typically specify the conditions in which systems can be used. It will be typically be mentioned as G1 - Mild. That standard is defined by the ISA 71.04 standard.
The sensor monitors for silver and copper corrosion and computes the severity over a rolling 30 days times frame.

MTBF impacted by corrosion
Corrosion impacts the life span of critical equipment. That life span is expressed in MTBF or Mean Time Before Failure.
In some level of corrosion can reduce the life span by up to 25%. In severe corrosive environments, this increases to more than 75%.
This shows that uptime in mission critical is significantly impacted by the level of corrosion.

| ISA Severity | MTBF Reduction |

| GX | more than 75% |
Corrosion: an OPEX and CAPEX risk
In the above table we've seen the impact corrosion has on the life span of equipment in mission critical environments.
A reduced MTBF entails a significant OPEX and CAPEX risk:
- OPEX: corrosion will cause systems to fail resulting in business continuity being impacted
- CAPEX: equipment manufacturers will typically void warranty if damage is caused by corrosion

Where does corrosion come from?
Electronic circuits use copper. Prior to RoHS, the exposed copper in electronics was soldered with lead protecting it against corrosion.
With the introduction of RoHS, lead could no longer be used and that protection is gone.
With the weakened protection of equipment due to RoHS, there are 4 main contributors to corrosion:
- temperature
- humidity
- air particles
- corrosive gasses
Monitoring for those risks with the right sensors enables you to put a corrosion risk mitigation strategy into place.

Recommended settings for G1 class environment
| Risk | Action | Part number |
|---|---|---|
| Temperature | Ideal temperature is 21°C (70F) with a ±1°C temperature change | ENV-TEMP or ENV-THUM |
| Humidity | rH should be below 55% and not change more than 6% per hour | ENV-THUM |
| Air Circulation | Air filtration and purification is paramount to keep corrosive contaminants out of the facility. Minimum 3 air changes per hour should be performed | ENV-AIRPRESSURE or ENV-AIRFLOW |
| Particles | Air particles from PM1 to PM10 should be kept below 70µg/m3. Particles larger than 1mm should be below 1,000µg/m3 | ENV-PARTICLE or ENV-DUST |
| Corrosive Gasses | Following limits in parts per billion (ppb) apply to mild environments: H2S <3 ppb SO2 <10 ppb CL2 <1 ppb NOx <50 ppb HF <1 ppb NH3 <500 ppb O3 <2 ppb |

Why monitoring corrosion
in mission critical?
Corrosion is the degradation of materials due to a chemical reaction with their environment.
It can be a major issue in data centers, substations, electrical panels, switchgear and other mission critical infrastructure for several reasons:
Safety: Corrosion can compromise the structural integrity of the equipment, potentially leading to failure and posing a safety hazard to personnel.
Reliability: Corrosion can cause equipment to malfunction or fail, leading to downtime and reduced reliability.
Cost: Repairing or replacing corroded equipment can be costly. In addition, corrosion can reduce the efficiency of the equipment, leading to higher energy consumption and costs.
ne of the main benefits of real-time atmospheric corrosion monitoring using sensors is the ability to detect corrosion early, before it becomes a major problem. Sensors can continuously monitor the environment and alert maintenance staff when corrosion is detected, allowing them to take corrective action before the corrosion causes significant damage.
Real-time corrosion monitoring can also help to prevent equipment failures and downtime. If corrosion is allowed to progress, it can weaken structural components and cause equipment to fail, leading to costly repairs and lost productivity. By detecting corrosion early and taking preventive action, real-time corrosion monitoring can help to extend the life of equipment and reduce the risk of costly failures.

Wired or Wireless
By default all sensors are connected to the SensorGateway (BASE-WIRED) using a CAT6 or higher RJ45 cable.
Using the optional Wireless Hub & Node modules, any sensor can be turned into a wireless sensor.
