Why Eltek
Rugged monitoring from the factory floor to the cloud
Whether you are proving thermal uniformity through a curing or heat-treatment oven, tracking conditions across a production line, or consolidating dozens of sites onto one platform, Eltek keeps measuring, and keeps its data, in demanding industrial settings. Wired and wireless loggers, including the high-channel-count Grant Squirrel SQ16Plus, work together on one connected solution.
What is industrial process and environmental monitoring?
Industrial process and environmental monitoring uses wired and wireless data loggers to track temperature, humidity and energy performance continuously across ovens, production lines, warehouses and multi-site estates, rather than by manual spot checks. Eltek's Grant Squirrel SQ16Plus and wireless GenII sensors work on one connected platform, alarming a breach by SMS or email and keeping audit-ready records for quality and process teams.
Process and through-process monitoring
Prove thermal uniformity through ovens, curing and heat-treatment with probes built for high-temperature and harsh settings, where close enough is not good enough.
High channel counts for complex sites
The Grant Squirrel SQ16Plus multi-channel logger handles process monitoring, energy analysis and HVAC performance alongside wireless GenII, on one platform.
Built so you never lose data
Robust wired and wireless links, long battery life and repeaters hold the network together across large, obstructed floorplates.
Real-time alarms and reporting
Instant SMS and email alerts on breach, plus scheduled, audit-ready reports for quality and process teams.
One platform, many sites
Integrate wired and wireless monitoring on a single platform that scales from one line to a national, multi-site estate.
Wireless or wired, matched to the measurement
Wireless GenII suits flexible, distributed and temporary monitoring, while wired Grant Squirrel DAQ suits high-density, high-precision measurements. Run both together on one connected platform.

From process ovens and production lines to cold stores and multi-site estates, Eltek provides the right monitoring solution for every industrial and manufacturing environment.
Oven & process profiling
Through-process temperature mapping to prove thermal uniformity in ovens, curing and heat-treatment, with high-accuracy probes built for demanding industrial settings.
Production environments
Continuous monitoring across the factory floor — from chilled production lines to ambient assembly areas — with wired and wireless sensors on one connected platform.
Food production & storage
Temperature and humidity monitoring for food production facilities, cold rooms and storage areas, with HACCP-ready records and real-time alarms.
ExploreWarehouses & cold storage
From ambient distribution warehouses to chilled and frozen stores, Eltek monitors continuously with real-time alarms, audit-ready records and multi-site consolidation.
ExploreEnergy & electrical measurement
Track energy consumption through the monitoring platform, plus voltage and current measurement using wired Grant Squirrel DAQ systems, alongside HVAC performance over time, to support efficiency improvements, carbon reporting and building-services optimisation.
Pressure monitoring
Monitor pressure across processes and plant using wireless GenII sensors and transmitters, on the same connected platform as your temperature and humidity monitoring.
Doors & equipment status
Monitor door and contact status, and use wired Grant Squirrel DAQ systems to monitor fixed plant equipment and complex sensor inputs.
Remote & multi-site monitoring
Consolidate dozens of sites or an unmanned facility onto one cloud platform with 4G/LTE connectivity, real-time dashboards and scheduled reports.
The platform
The Darca Solutions Suite
Three connected solutions. One complete platform for manufacturing and industrial environments.
Darca Collect
High-temperature and harsh-environment probes, the Grant Squirrel SQ16Plus, GenII transmitters and repeaters, the wired and wireless sensing layer for the plant floor.
Explore
Darca Connect
The SRV450 hub gathers the wireless network and SMS450 alarms escalate breaches to the right person fast.
Explore
Darca Command
One dashboard across every line and site, with the trend analysis and reports quality and process teams need.
ExploreProven on the plant floor
When “close enough” is not good enough
In through-process and oven applications, a few degrees of variation across the load is the difference between a sound cure and a failed batch. Eltek proves compliance batch by batch: eight lance probes (±0.1 °C) deliver the kill-phase temperature evidence regulators require in large-scale composting, and on mixed industrial sites wireless GENII and wired Grant Squirrel DAQ combine into one hybrid architecture under one supplier. On multi-site estates, one connected Darca platform ties every line and location together.

ExploreFrequently asked questions
What is the best temperature monitoring system for a manufacturing or production line?
The best system depends on the process, but a manufacturing temperature monitoring system should combine rugged wired probes for high-temperature and harsh points with wireless GenII transmitters for hard-to-cable areas, on one platform. Eltek logs continuously across the line, alarms on breach by SMS and email, and produces audit-ready reports for quality and process teams.
What features should an industrial temperature monitoring system have?
An industrial temperature monitoring system should capture data continuously without gaps, hold high and low alarm thresholds that escalate a breach by SMS and email, scale to high channel counts across large or multi-site estates, and generate audit-ready reports. Eltek delivers all of this, including the high-channel-count Grant Squirrel SQ16Plus logger, on one connected Darca platform.
What types of temperature sensors are used in manufacturing?
Industrial temperature monitoring typically uses thermistor, thermocouple and PT100 probes chosen for the temperature range and environment, from chilled storage to high-temperature ovens, alongside 4-20mA and voltage inputs for other process signals. Eltek data loggers accept these wired probe types and combine them with wireless GenII transmitters on one connected Darca platform.
Should a factory use wired or wireless temperature monitoring?
Both have a place. Wired probes suit fixed, high-accuracy points such as process ovens and permanently installed equipment, while wireless GenII transmitters reach moving lines, large obstructed floorplates and areas where cabling is impractical. Eltek runs wired and wireless sensing together on one connected platform, so a plant is not locked into a single architecture.
How does temperature monitoring support HACCP and food-safety compliance?
Under HACCP, temperature is a critical control point at steps such as chilled storage, cooking and cold holding, and it must be monitored and recorded against defined limits. Eltek monitors these points continuously rather than by spot checks, alarms the moment a limit is breached, and stores time-stamped records that evidence control for HACCP and BRCGS audits.
How do you prove thermal uniformity through an industrial oven or curing process?
Through-process mapping places probes at every point in the load that matters, built for high-temperature and harsh settings, so a few degrees of variation across the load is caught rather than assumed. The Grant Squirrel SQ16Plus multi-channel logger handles this alongside wireless GenII sensors on one platform, with real-time SMS and email alerts on breach and scheduled, audit-ready reports for quality and process teams.
