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.
