Miniature stainless steel temperature data loggers are about the same size as a watch battery, opening up possibilities for temperature logging in places previously not possible
Signatrol is introducing its SL50 series of miniature stainless steel temperature data loggers.
The company says that the SL51T and SL52T, measuring about the same size as a watch battery, open up exciting possibilities for temperature data logging, hitherto not possible because of size and sealing constraints.
An Atex certified version, due to be available shortly, will further extend the SL50's capabilities.
Both versions are self contained, single channel temperature data loggers, and depending upon the model chosen, they can operate over a temperature range from to -40 to +125C.
This offers the opportunity for them to be used in many sterilising and high temperature washing environments, as well as freezers and chillers.
The low cost, water resistant, SL51T can store up to 2000 readings over a temperature range of -40 to +85C: the fully waterproof SL52T can be set up to record 4000 temperature readings in high resolution mode (11 bit or 0.0625 C) or 8000 readings in low resolution (8 Bit or 0.5 C) mode with an accuracy of better than 0.5C over a range of 0 to +125C.
Their small size makes them ideal for use in a wide range of applications, especially in the food and beverage, and pharmaceutical industries.
The loggers are small enough to fit inside glass bottles and food packs, and units have already been used in areas as diverse as vinegar distillation and chocolate manufacture.
Set up and data download is achieved simply and quickly using the SL50R Button Reader, which interfaces to the RS232 or USB port of a PC.
Sampling rates can be set from one second to twenty-four hours and the built-in battery can power the logger for up to ten years or one million readings, depending on the application.
The reader is totally compatible with Signatrol's universal TempIT-lite operating software and data can be securely stored and retrieved at a later time for display in graphical format.
Both models can be set up to record in a continuous first-in,-first-out, or stop when full mode.
The software can be up-graded to TempIT-Pro which provides important additional features such as data table, export data, email graphs, snap to trace, and automated MKT (mean kinetic temperature) calculations.
The TempIT software is a single package that is used to set up all Signatrol's data loggers and enables different types of logger to be seamlessly integrated for different applications.
Each unit has the capability of storing specific manifest details and features a unique serial number etched into the base for traceability purposes.
The delayed start facility of up to 45 days allows the logger to be programmed to commence with a particular process or transport schedule.
Alternatively it can be set to start logging when triggered by an event, for instance, when a particular temperature threshold is exceeded.
