Environmental & temperature monitoring

Sensors, data loggers and alarm modules for temperature, humidity, CO2 and leaks in food, pharma, laboratories and storage.

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.

PET-7017-10 CR PET-7017-10 PoE Ethernet I/O Module, 10/20-ch Analog Input

The PET-7017-10 is a PoE-powered Ethernet analog input module for engineers who need voltage or current measurement on a networked I/O node. Its inputs can be set as 10 differential or 20 single-ended channels in software, and each channel can be given its own range, so one module can serve mixed sensor types on the same network.Each channel offers a choice of voltage ranges from ±150 mV to ±10 V and current ranges of ±20 mA, 0 ~ 20 mA and 4 ~ 20 mA, selected with jumpers. Resolution is 16-bit, and the module has two sampling modes: normal mode at 10 Hz total and fast mode at 50 Hz total. Open wire detection is available for 4 ~ 20 mA inputs, and differential channels are rated for 240 Vrms overvoltage protection.Configuration and monitoring are handled through a built-in web server with Web HMI, and the module supports Modbus TCP and Modbus UDP. Access is controlled by ID, password and IP filter. The unit is powered either from PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block, and it mounts on a DIN rail.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment
