As part of research and development work into lime manufacture, a Tinytag Ultra 2 Thermocouple data logger is being used in the laboratory to accurately record temperature change information.
Lincolnshire-based Singleton Birch is a lime manufacturer and
supplier, extracting the raw material - calcium carbonate - from
their quarry and then burning it in kilns to make lime - calcium
oxide. Their product range includes quicklime, hydrated lime,
natural hydraulic lime, graded chalk, aggregates and other
specialist products and services.
Matt Austin, a Chemist with Singleton Birch, is using a Tinytag Ultra 2
Thermocouple logger in the laboratory to gather information as
part of research and development work to monitor the temperature
rise of calcium oxide when water is added. The rise in temperature
needs to be accurately measured as this indicates how reactive the
lime is at different stages, which means it can then be determined
for what final application the lime can be used. The temperatures
need to be logged at different intervals throughout the process. In
order to gather as much data as possible continuous monitoring is
required with data downloaded after every test.
The thermocouple logger is
ideally suited to providing the versatile and accurate monitoring
demanded by this application. The temperatures being monitored
start at 20°C and peak at about 80°C: as soon as the lime is added
to the water the temperature rises rapidly and needs to be
measured. Matt concludes "I chose the Tinytag thermocouple
logger as it is compact and easy to use with the Tinytag Explorer software provided. It meets my
needs as I can easily configure the unit at the parameters I have
chosen through the software and then download the data when needed.
I am very happy with the performance of this data logger. It has
proved to be reliable and user friendly."
