New RFID technology wireless pressure sensors and data loggers

Bestech Australia has released the new 21D/ DC RFID series designed
to provide unique solutions that combine industrial pressure sensing
with RFID wireless communication and data logging.

Integrating extremely sturdy, tried-and-tested industrial pressure transmitters
and RFID wireless technology, the new pressure transponders are highly
resistant to environmental impact, with an ultra-compact stainless steel
housing, also available in Hastelloy C-276.

The new RFID wireless pressure transponders offer high accuracy with
outstanding long-term stability, hysteresis-free; display temperature alongside
accurate pressure reading; operate in a pressure range of 3 to 1000 bar; and
have freely programmable measuring point numbers (8 alphanumeric characters).

The D line piezo-resistive transmitters used to measure pressure are
based on KELLER’s chip-in-oil technology. The laser-welded, hermetically sealed
stainless steel housing, which is filled with oil for pressure transmission,
contains the pressure transducer and the ultra-energy-efficient compensation
electronics with I2C interface.

Series 21 D Passive RFID
pressure transponders

The plastic cap houses the interface to the pressure transmitter as well
as all RFID components including the antenna. The scanner provides the power
required to log instantaneous values.

Series 21 DC RFID data loggers

Featuring an extra data recording functionality, the pressure
transponders also include an integrated battery that allows data to be measured
and stored. Stored measurements are transmitted wirelessly and exclusively via
the RFID interface.

Series 21D/ DC RFID are recommended for maintenance applications where concerns
of power supply and long term monitoring of pressure feedback are
addressed. The pressure transponders can also be used in mining where 360-ton
trucks run non-stop and require preventive maintenance at regular intervals.

RFID pressure sensors deliver multiple advantages include time and cost savings;
safety; nil oil loss; and digital traceable readings instead of manual readings.
