Industrial site temperature monitoring

Temperature monitoring is often required in industrial halls due to strict regulations. Most industrial halls and sites have complex structures and a high level of electric/radio jamming so the standard industrial RS-485 bus for sensor network covers most cases.

The solution with Poseidon2 4002 offers many benefits:

  • High scalability of sensors (temperature, construction, producer, costs)

  • Combining RS-485 bus (up to 1200m), 1-Wire bus (max 60m), Digital Inputs

  • High reliability of data transmission

  • Quick and easy fault detection

  • Remote access to monitoring data and alerts

  • Sending data and alerts by e-mail, SMS gateway, SensDesk Technology portal, custom SW, or cloud third-party applications

  • Uses standard protocols HTTPs, IPv6, SNMPv3, MQTT

RJ45 - RS-485 sensors have maximal distance of 1000 meters, a daisychain wiring structure from the RJ45 port on the Poseidon2 4002 device.

Poseidon2 4002

  • 16x 1W UNI (RJ11) sensors,

  • 24x RS-485 sensors (daisy chain topology),

  • 12x DI (Digital Inputs / dry contact),

  • 8x VDO (Virtual Digital Output),

  • 4x DO (Digital Outputs / relay NO/NC)

Poseidon2 monitors and controls sensors and digital I/O over the network using secure M2M protocols (HTTPs, IPv6, SNMPv3). With support for over 50 SNMP and SCADA applications, Poseidon2 devices can be integrated in a wide range of monitoring and control systems. MQTT protocol enables integration in IoT solutions.

SensDesk Technology portal

SensDesk Technology portal provides essential monitoring of your technology and workspace reliably and economically 24/7.With the SensDesk Technology portal, you can have a perfect overview of critical temperatures, power to the machines, motion, air conditioning, battery backups, and more. All of that is in one reliable system that can be installed in your factory and does not have to be in a public cloud.By using the portal you get:

  • Overview of all your sensor values - All your sensors are in your pocket 24/7

  • Reliable e-mail/SMS/Call alerting in case of a problem (data out of safe range)

  • Reports and multigraphs with several measured values for better orientation

  • system that can be integrated with 3rd party software thanks to open API (XML, SNMP)

  • easily accessible data history up to 2 years
