Many processes and stored goods depend on stable conditions. Food production and storage need documented temperatures for HACCP, pharmaceuticals and blood products need controlled storage, laboratories and server rooms need a stable climate, and museums and archives need controlled humidity. The common requirement is continuous measurement, reliable logging and an alarm when a limit is exceeded.

Typical tasks

  • Temperature monitoring of cold rooms, freezers and storage areas
  • Humidity, dew point, CO2 and CO measurement for indoor climate and safety
  • Leak detection under raised floors, along pipes and in technical rooms
  • Logging measurements as documentation for HACCP and quality audits
  • Local and remote alarms with sirens, displays and notifications

Sensors and data loggers

The CL series data loggers measure temperature, humidity and dew point, combined with CO2, CO, particulate matter (PM1, PM2.5, PM10), TVOC or gases such as O2, NH3 and H2S depending on the model. They log data internally, communicate over RS-485 and Ethernet with PoE using Modbus RTU, Modbus TCP and MQTT, and are also available with Wi-Fi. Liquid leakage detection uses sensing cable laid along pipes and floors, and signals a leak to the monitoring system.

I/O for existing sensors

Where sensors are already installed, temperature input modules read thermocouples, RTDs and thermistors directly. RS-485 modules such as the M-7000 series do this over Modbus RTU, Ethernet modules over Modbus TCP, and wireless I/O covers locations that are difficult to cable.

Alarms and displays

Alert modules play voice or tone messages and drive sirens, and iKAN LED message displays show measured values or alarm texts where staff can see them. Combined with an edge controller or an I/O module with logic rules, alarms can also be sent by e-mail.

Documentation and data

For HACCP and quality systems, measurements must be stored with time stamps and kept available for inspection. Data can be logged locally in the sensor or module, collected by an edge controller, or stored centrally in SCADA, a database or IoTstar.

Example: cold storage for food

Each cold room and freezer gets a temperature sensor read by M-7000 RTD input modules on a shared RS-485 line, and a CL series logger monitors humidity and CO2 in the packing area. An edge controller collects all values, stores them with time stamps for the HACCP records and sends an e-mail and switches a siren if a room stays above its limit for longer than the set delay.

What to check before you choose

  • Measuring range and accuracy, especially for freezers at −30 °C and below, and for humidity
  • Logging interval, storage capacity and how long records must be kept
  • Power and connection: mains, PoE or battery; wired, Wi-Fi or ZigBee
  • Ingress protection and condensation in cold rooms and wet areas
  • Who receives the alarm and how: local siren, display, e-mail or SCADA

Send us a list of rooms or measuring points, and we will propose sensors, logging and alarm handling.
