Signatrol's spYdaq System

Wireless Temperature and Relative Humidity Monitoring

spYdaq® is a system comprising of a number of radio transmitting sensors that measure parameters and send them securely by using a license free radio network to a central Basestation. The data are sent using a Manchester Encoded error correcting code with multiple transmissions which, when combined with Antenna Diversity, ensures there is no loss of data in normal use from a properly installed system.
Up to 16 transmitters can communicate to a single base station with each transmitter capable of having up to three inputs: Temperature, Relative Humidity or Universal inputs can be configured to accept almost any type of measurement sensor. The base station collects the data from the transmitters and connects via an RS232 serial port configured as a Modbus slave to spYview software or any other Modbus master.
The Basestation checks locally for alarm conditions with inbuilt audio and visual alarms as well as providing a switched contact output that can be used to trigger external devices. Alarming locally means that potential trouble spots can be quickly detected and corrective action taken immediately, perhaps saving an entire batch from damage.
Main Features   Benefits and Applications
The wide range of inputs offered by the universal transmitter design enables virtually any parameter to be measured and logged by connecting an appropriate sensor. Parameters that can be measured and logged are:
  • Temperature
  • Humidity
  • Pt100
  • Thermocouple Types J, K, T, R, S
  • 4-20 mA - Scaled in engineering units
  • Voltage
  • Contact Closure
  Museums and art galleries are in constant need of collecting and collating critical environmental data to ensure the preservation of their displayed artifacts. Whether on public display or in storage, old and delicate items are mostly susceptible to damage when changes occur to their surrounding environment. It is important that the relative humidity and temperature in particular are logged on a regular basis. Using radio telemetry gives several advantages. The installation cost is low, the transmitters do not have to be wired; so the building fabric is not disturbed, labor savings are made because the data does not have to be collected and the data is provided on a live basis. It is not just the large national museums that have found this technique advantageous; smaller, established regional galleries and museums have also benefited from the cost savings that radio brings. The ability to transfer data via modem has enabled establishments to monitor remote site storage, museums and properties without the need to travel to the site on a regular basis.
    With multiple channel Pt100 transmitters and single channel mA and DC voltage transmitters available the possible applications are limitless. It is now becoming more and more of a requirement to monitor critical control points to satisfy HACCP or EFSIS requirements. Using the SL413, a single radio transmitter can handle up to four Pt100 temperature sensors which, when placed in chill cabinets, cold rooms or freezers, enable the temperature to be accurately monitored. With up to 200 radio transmitters available in a system over 800 temperature points can be monitored without having to move from your office.
