With both a dual and quad-channel Pt100 version available, Signatrol's SL400 Radio Link Data Collector allows the user to measure, display and record real time temperature and humidity data
Signatrol's claim to be the UK's leading supplier of data loggers has been strengthened further by the introduction of the SL400 radio link data collector.
This system, which allows the user to measure, display and record real time temperature and humidity data, 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 basestation, permanently connected to a PC, and up to 256 remote monitoring stations.
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 The SL400 uses a pan-European licence-free 434MHz radio transmission frequency and offers significant savings in terms of wiring and installation costs, whilst providing the ultimate in flexibility.
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 basestation, 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 multiline traces - and graphics can be added which show the location of the remote transmitters.
The basestation 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 offers 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.
