AVD Series Low-Profile Pressure Transmitters
TDK’s compact piezoresistive pressure transmitters are suitable for the pressure measurement of air and non-aggressive gases
TDK’s AVD series high-precision pressure transmitters with an extremely low-profile design are available in three versions for different pressure measurement ranges, including 0 mbar to 16 mbar, 0 mbar to 100 mbar, and 0 bar to 7 bar.
The AVD 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 mm x 40 mm footprint, the insertion height is only 12.9 mm, enabling use even in confined spaces applications. 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, these transmitters can 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 inter-integrated circuit (I2C) 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.
These 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.
