Reactor Temperature Monitoring (Batch Control & Product Quality) — ATEX
Quality control, energy efficiency
Temperature
Quick Overview
| Problem | In chemical and process industries, reactor temperature is the most critical parameter for reaction kinetics, product quality, and safety. Temperature deviations can trigger runaway reactions, off-spec batches, or emergency shutdowns—especially in ATEX-classified environments where manual intervention is risky and slow. |
| Solution | Sensa.io’s ATEX-certified temperature sensors provide continuous, high-accuracy monitoring of reactor temperature, delivering real-time visibility for safe batch control and process optimisation. |
| Value | Improved batch quality • Reduced safety risk • Lower scrap rate • Stable, repeatable processes |
| ATEX | Zones 0–2 • Ex ia IIC T4 Gb certified temperature sensors |
The Operational Challenge
Chemical reactors are used for:
- Batch and semi-batch reactions
- Continuous chemical synthesis
- Polymerisation, neutralisation, and mixing processes
Temperature directly affects:
- Reaction speed and yield
- Selectivity and by-product formation
- Pressure generation inside the reactor
- Safety margins during exothermic reactions
Common challenges include:
- Localised overheating or hot spots
- Sensor drift or loss of signal from wired probes
- Limited measurement points on legacy reactors
- Delayed operator response to rapid temperature rise
Traditional temperature monitoring often relies on:
- Single wired thermocouples
- Periodic manual verification
- Reactive alarms after thresholds are exceeded
These approaches can be insufficient in fast-changing reaction conditions.
Why Continuous Temperature Monitoring Matters
Temperature is the primary control variable in most chemical reactions.
Continuous monitoring enables operators to:
- Detect deviations before runaway conditions develop
- Maintain tight temperature control during critical phases
- Improve repeatability between batches
- Reduce thermal stress on reactor walls and seals
Accurate, real-time temperature trends support safer operation and higher product consistency.

FAQ - Common Questions
Are Sensa.io sensors compatible with any gateway or network?
What ATEX certifications apply to Sensa.io devices?
All hazardous-area models are certified Ex II 2 G Ex ia IIC T4 Gb and IECEx approved for Zones 0–2.
What is the typical battery life?
Up to 10 years at 15-minute intervals, depending on signal strength and environment.
How are the sensors integrated into existing systems?
Through standard protocols — LoRaWAN, Modbus, MQTT, REST API — no proprietary middleware needed.
How does predictive maintenance reduce OPEX?
Early anomaly detection reduces emergency interventions by 30–40 %, extends equipment life and lowers energy costs.
What does the Sensa.io Valve Position Sensor actually measure?
The device detects real-time valve position states—open, closed, or intermediate—with high accuracy. It continuously sends this information wirelessly to your monitoring dashboard.
Can this sensor detect partial valve movement or stuck valves?
Yes. The sensor identifies irregular patterns such as partial movement, delayed response, or stuck valves, enabling early maintenance before failure occurs.
Is this sensor suitable for manual, motorized, and actuated valves?
Yes. It supports a wide range of valve types including ball, gate, butterfly, actuator-driven, and manual valves.
How fast does it update the valve position?
You can configure the reporting interval—from seconds to minutes—depending on your operational and battery needs.
How long does installation take?
Most installations take under 10 minutes. The sensor mounts using brackets or clamps without modifying existing valves.
