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.

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.

Proven 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 logs temperature at every point that matters and proves uniformity, and on multi-site estates one connected Darca solution ties every line and location together, with the trend analysis and audit-ready reports quality and process teams rely on.

Frequently asked questions

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.

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.

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.

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.

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.

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.
