TDK releases high-precision pressure transmitter with ultra-thin design

TDK Corporation recently introduced a new ultra-thin, high-accuracy pressure transmitter in its AVD series. The transmitters with B58621V ordering codes are available in three versions for different pressure measurement ranges including 0 to 16 mbar, 0 to 100 mbar, and 0 to 7 bar.

The series offers high precision levels for low-pressure ranges, such as ±1.75% full scale (FS) with a pressure range of 100 mbar. With a 31 x 40 mm footprint, the insertion height is only 12.9 mm, which enables use even in applications in confined spaces. The compact piezoresistive pressure transmitters based on MEMS technology are suitable for the pressure measurement of air and non-aggressive gases. In addition to differential pressure measurement, they can also be used for overpressure measurement in a temperature range of -20 °C to +70 °C.

The transmitters have two self-locking pressure ports for assembling hoses with an inner diameter of 4 mm and offer an I2C (Inter-Integrated Circuit) digital output with 14-bit resolution; I2C is a standard digital interface for communicating with controls in industrial applications. An additional temperature signal output is also available via the I2C digital interface. The transmitters come equipped with two plug connectors to easily implement daisy chain systems which enable several sensors in one single network. By combining these benefits, the sensor systems are ideally suited for demanding industrial applications such as pressure level measurement, flow control, and filter monitoring. Applications include pumps and compressors, pneumatic systems, building management systems, and more within Industry 4.0 markets.
