FORGOT YOUR DETAILS?

A new wireless system for continuous accurate & reliable data monitoring of temperature and humidity that makes your HACCP compliance requirements an easy task

An easy-to-use system that automatically measures, documents and issues alarms whenever limit values are exceeded.

The system is ideal for: 

  • Recording quality data in production and storage environments
  • Continuous monitoring of climate in industrial plants and facility maintenance
  • Quality assurance in the pharmaceutical and cosmetics industry
  • Ensuring ambient conditions are maintained in buildings such as hospitals and museums
  • Research and development laboratories

Sigma offers an extensive range of Radio and Ethernet probes making it a truly flexible temperature and humidity monitoring solution for a wide range of applications. The software is easy to set up and use and stores data centrally, providing traceability of important quality data.”

The heart of the wireless system is the Base Unit, which has the ability to store 40,000 readings per measurement channel, the equivalent to around one year of memory capacity at a rate of 15 minutes. Unlike previously available monitoring systems, a PC is not required to be continuously connected to the system as the Base Unit has the ability to record and document measurements.

 

The base unit can incorporate data from up to 150 radio and Ethernet probes or 254 measurement channels, making it a truly flexible system. A benefit of the new measuring system is the  radio probe,

which removes the need for complex cable routing and which can be used in conjuction with Ethernet probes in one system. During a monitoring cycle, the probes save their measurement data and send it to the central Base Unit at regular intervals. If a limit value is exceeded, a radio link is established immediately. The bidirectional transmission ensures that the measurement data is only recorded by the Base Unit and not interfered with by other radio systems. An alarm sounds in the event that the radio link is interrupted by

obstacles. The memory in the probe ensures that the measurement data is not lost in the event of interference to the radio link.

As the radio probes are available with internal and external sensors, with or without displays, they cater for every application.

In open space the transmission distance is approx. 300m at a frequency of 868MHz and approx. 100m at a frequency of 2.4 GHz. In buildings the transmission distance is influenced by the structural conditions such as walls, refrigerator doors, or metal doors. When necessary the radio link can be strengthened and the distance increased by using a router.

The Ethernet probes can be connected directly to existing LAN infrastructure. This allows for data transfer over greater distances. Ethernet probes use mains power and therefore can be used over long periods.
The internal memory guarantees the data is not lost in the event of a network failure or power failure. Ethernet probes are equipped with a display which shows the current measurement data and probe status.   Through the use of a converter the signal from a radio probe can be converted into an Ethernet signal. This allows the system to be as dynamic and flexible as you need it to be.

The Software is easy to install and use and does all the initial system and probe configurations. All measurement data can be saved centrally on the programs database and called up as a table or graph.

Uses/Applications:
