Alphasense Pellistors are available in two housing
sizes: A and D for fixed installation applications. The innovative
design of the Alphasense Pellistor range provides high quality,
low power (only 190mW) and excellent poison resistance.
CH-A3 is a drop-in (20mm diameter) replacement
to existing products with improved stability and poison resistance.
CH-D3 is a unique miniature size - 11.5mm height,
15mm diameter, complementing the existing and fast-growing Alphasense
D sensor family - with the same good stability and high poison resistance
of the CH-A3. The CH-D3 has full ATEX, IECEx, UL and CSA certification
from -40°C to +50°C at 1.25W, optimising portable gas detector
battery life.
All pellistors are housed in certified flameproof
chambers.
Alphasense tests the performance of every sensor;
results are stored on our database, giving full traceability for
all sensors. The unique Automatic Test and Validation (ATAV) system
controls initial sensor stabilisation and runs complex tests under
computer control. This computerised system also ensures traceability
as tested sensors are moved direct to despatch with their unique
barcodes. The ATAV system also runs full validation testing, monitors
sensors for long term performance and its generated statistics are
used for statistical process control.
