Ethernet, wireless, temperature, humidity monitoring

The new Testo Saveris system monitors temperature and humidity in industrial control, food service, and processing applications via either wireless or Ethernet connection. Saveris “effectively automates data collection and transmission with built-in data security and integrity,” says U.S. marketing manager for industry & food, Robert Bove. Three main components are wireless and / or Ethernet probes, a base, and system software. Wireless probes measure and record temperature and humidity and transmit recorded data at regular intervals to the base, which records only the data from the probes and sounds an alarm if the link is interrupted. In that event, the data in the probe and base are secure until operation resumes. In the field, the wireless probe to base transmission path is about 328 ft (100 m) at 2.4 GHz. A router can optimize signal strength around structural walls, equipment, or metal doors. Ethernet capable probes are available for longer distance data transfer from the probe to the base using an existing LAN infrastructure. The base can save up to 40,000 readings without a PC connection. Basic software provides essential data collection and alarm functions. Professional software adds network integration, multiple data display screens, on-line monitoring, integration of data displays into photo references, and integration into a client-server network. www.testo.com Testo Inc.
Probes are available with internal and external temperature and humidity sensors and easily adapt to any application. Current measurement data, battery status, and signal strength are shown on optional displays.
Since Ethernet probes run on ac power, rather than batteries, they can be used continuously. Even in the event of a power outage or the loss of the LAN connection, data remains safe in the probes’ on-board memory.
Each base can accommodate a maximum of 254 channels or up to 150 single channel probes in many combinations. Like a command center it displays and issues alarms when limit values are exceeded via SMS or email alert.
Configuration can suit an application based on specifications or it can be purchased pre-configured and supplemented with individual components. Set 1 starter set consists of a base, three NTC wireless temperature probes with without display, a power supply for the base and the SBE software package including a USB cable. Set 2 consists of a base, five NTC wireless temperature probes with display, a router, two power supplies and SBE software with USB cable. Set 3 has a base including GSM module for SMS alarm, antenna with magnetic base, five wireless probes with display, router, two power supplies and SBE software with USB cable.
