A unique miniature radiation thermometer measuring just 28mm x 4mm, JRG/A is specifically designed to monitor temperature consistency in plate and float glass applications.
JRG/A’s compact design enables it to make difficult near-field temperature uniformity measurements – ensuring temperatures are kept stable or altered with highly controlled gradients during cooling and annealing, and kept uniform across the bath width in the float process.
JRG/A’s fast response measurement is provided by precise infrared waveband monitoring between 4.8-5.2µm. This ensure the thermometer does not ‘see’ through the glass, providing the critical accurate surface measurement you depend on.
Available in operating lengths of up to 4.5m (15ft), the precision glass thermometer and probe is ideal for use in the tin bath and annealing lehr on a glass float line.
MADE FOR GLASS MEASUREMENT
With the wavelength restricted to ensure surface temperature measurement, the JRG/A is designed specifically to provide the most accurate result possible for one application – measuring glass temperatures. This makes it easy to set up, use and maintain in this process.
RUGGED DESIGN
JRG/A is protected by a water-cooled probe incorporating an air purge, ensuring the measurement is unaffected by the high process temperatures. The only maintenance requirement is occasional inspection and wipe clean of the probe if necessary.
FAST RESPONSE
After a short setting time of 15s to acclimatise to the hot ambient temperature of the process, the thermometer quickly reacts to temperature anomalies - taking just 1s to reach 98% of an instantaneous change.
The JRG/A is AMETEK Land’s application-specific temperature measurement solution for plate and float glass.
