Sawing machine
A connected industrial saw has its coolant monitored and records status and process data such as cutting volume per hour. Inspection rounds are no longer needed, and operators see downtime and fault causes in real time.

Industrial saw monitoring: coolant levels and sawmill KPIs
On a hacksaw machine, ifm uses the LR7020 level sensor with a probe cut to length to measure the coolant in a tank holding around 50 litres. The io-key sends the values via cellular network to the moneo Cloud with no on-site IT infrastructure; only the power supply and sensor need connecting. In moneo, warning and alarm limits can be set, and notifications go to the responsible colleagues by email or Teams. In the sawmill, machine data is recorded with sensors and sent via an edge gateway to the Cumulocity IoT cloud platform. logicline's KPI app, built with its assets360 toolkit, also integrates data from existing databases.
The examples come from metalworking and the timber industry. ifm uses the io-key to monitor the coolant of a hacksaw located in an area without IT infrastructure: when the level drops, the alert arrives with enough lead time for refilling, before a shortage wears out the saw blade. A global manufacturer of sawmill technology is expanding its portfolio with digital services together with logicline. In the app, sawmill and manufacturer see machine availability and performance, production targets, downtime and fault causes. Podcast episode #49 describes how the machine builder offers its customers digital added value such as condition monitoring.

Industrial saw monitoring: frequently asked questions
How is the metalworking fluid of an industrial saw monitored automatically?
A level sensor in the tank monitors a saw's metalworking fluid and reports its values automatically to a platform. On a hacksaw, ifm uses the LR7020 sensor and the io-key, which transmits the data via cellular network to moneo. The level fluctuates due to carry-over on the material and evaporation, and the emulsion should not become too concentrated. If the level falls below a defined limit, maintenance receives a notification.
Why does metalworking fluid concentration rise on a saw?
Concentration rises because water evaporates from the open tank and is carried away on the material during sawing. To keep the emulsion from becoming too concentrated, it needs regular topping up. ifm measures the level with the LR7020 sensor, whose probe rod is shortened to 19 cm so that it does not measure the bottom of the 20-centimetre-deep container. When the level drops, moneo sends a notification with lead time for maintenance.
What does sawmill software for connected saws deliver?
Sawmill software such as logicline's KPI app provides real-time saw data on availability, performance, downtime and fault causes. In the logicline solution, machine data is recorded with sensors and sent via an edge gateway to the Cumulocity IoT cloud platform. A mobile KPI app shows figures such as cutting volume per hour and whether production targets are being met. Learning algorithms are also intended to detect whether faults are emerging.
Which digital services can a sawmill equipment manufacturer offer?
A sawmill equipment manufacturer can offer services based on connected machines, such as condition monitoring, predictive maintenance and an overview of where each machine is in use. A global maker of band saws and breakdown saws is expanding its portfolio this way with logicline. The data can be accessed via a smartphone app. According to podcast episode #49, only those who really need specific data are given access to it.

Pump
Pump monitoring with IoT records vibration, temperature, pressure and energy consumption of running pumps. Operators detect damage and faults before a pump fails and plan maintenance by condition rather than at fixed intervals.
Compressor
With IoT, compressor maintenance follows actual condition: sensors record current consumption, pressure, temperature and running times. Operators detect creeping damage and unused running time early and cut energy and service costs.
Electric motor
Motor condition monitoring with IoT continuously measures the vibration, temperature and current draw of electric motors. Operators detect imbalance, bearing damage or winding faults early and replace motors based on condition rather than after a failure.
Packaging machine
OEE software automatically records run times, downtime, speed and rejects on packaging machines from the machine signals. Operators see where their lines lose performance, and machine builders use the same data for remote access and digital services.
Refrigeration system
A refrigeration monitoring system makes service plannable: temperatures, refrigerant circuit pressures, compressor status and energy consumption flow into a platform in real time. Operators and service partners detect faults early, avoid unnecessary site visits and reduce excess consumption.
Air conditioning system
Commercial air conditioning systems in offices, retail branches and data centres can be monitored remotely with IoT. Operators see energy consumption, temperatures and faults in one place, detect failing compressors or refrigerant shortages early and plan service visits precisely.
