Radio link data collector meets EU
directive
Latest radio link data collector which meets the new European RTTE directive 99/5/EC, which becomes mandatory in December 2002, and covers a wide range of radio and telecommunications equipment.
Signatrol's claim to be the UK's leading supplier of data loggers has been strengthened further by the introduction of their new SL400 Radio Link Data Collector which meets the new European RTTE directive 99/5/EC .This directive, which becomes mandatory in December 2002, covers a wide range of radio and telecommunications equipment and sets about harmonising the massive array of existing legislation relating to emissions and allocation of frequency bands New style EU directives are having a steadily increasing influence on equipment and because there are transition periods to allow changes to take effect, it is not uncommon for these directives to enter the European market place with a whimper rather than a bang

Data collected remotely
Signatrol's claim to be the UK's leading supplier of data loggers has been strengthened further by the introduction of their new SL400 Radio Link Data Collector.
Miniature logger gets into tighter places
Measuring only 17mm in diameter and 6mm high, this fully sealed, stainless steel unit truly can be described as miniature and opens exciting applications for temperature data logging.
Unfortunately the consequences for manufacturers and users alike can be significant and more often than not, companies leave it to the last moment before implementing the directives.
Radio telemetry equipment which is covered by 99/5/EC is increasingly being used in a wide range of industrial and domestic applications.
The SL400 is one of the few products of its kind which is already approved to meet the new legislation.

Remote pressure data logger has built-in display
A stainless steel pressure data logger is ideal for applications where remote recording of pressure trends is required.
Radio link data collector offers high accuracy
A very accurate 16 bit radio link data collector allows the user to measure, display and record real time temperature and humidity data.
Portable data log tags watch sensitive products
Self-contained temperature logging tags monitor temperature sensitive products such as food, pharmaceuticals and blood products during transportation or processing.
The new directive is abolishing the old wide band 435 MHz frequency range replacing it with a narrower, lower power band, covering frequencies from 433.050 MHz to 434.790 MHz.
Existing equipment using the old frequency can continue to operate for a fixed period but systems cannot be extended or partially upgraded with new equipment.
If equipment needs replacing or extending then the complete system must be replaced.
The SL400 system allows the user to measure, display and record real time temperature and humidity data and is already finding application in cold stores, supermarkets, warehouses, laboratories, computer buildings, museums and art galleries.
Both a dual and quad-channel Pt100 version is also available.
In addition to measuring temperature and humidity, the SL400 can also be configured to measure light level and UV content, vital parameters in buildings such as art galleries, museums and stately homes.
The SL400 system consists of a receiving base station, permanently connected to a PC, and up to 256 remote monitoring stations.This offers significant savings in terms of wiring and installation costs, whilst providing the ultimate in flexibility Each station transmits data to the base unit and can have up to four sensor inputs, giving a total capability of 1024 channels per installation.
The frequency of data transmission can be set from 15 seconds up to 90 minutes Each remote transmitter has a built-in, long life, battery providing up to five years life at a sampling rate of 20 minutes and can be mounted up to 300m away from the base station, extending to 1000m with a direct line of sight.
An optimal liquid crystal display is also available to provide local indication of temperature and humidity.
The Windows based software can be configured to provide the operator with measured values in a variety of standard formats -from simple bar graphs to multi-line traces, and graphics can be added which show the location of the remote transmitters.
The base station uses the PC's hard disk to store readings.
However, if the computer is turned off, the base station will store readings in its own internal memory for up to a week and then down load them automatically when the PC is turned on again.
Signatrol offer full support on installing and setting up the SL400 as well as advice on how to get the best out of the system.
The SL400 is part of Signatrol's extensive range of data loggers and instrumentation.
