AVD Series Low Profile Pressure Transmitters

     TDK's AVD series of high-precision pressure transmitters feature an ultra-low profile design and are available in three versions for different pressure measurement ranges: 0 mbar to 16 mbar, 0 mbar to 100 mbar and 0 bar to 7 bar.

     The AVD series provides high accuracy levels for low pressure ranges, such as ±1.75% full scale (FS), over a pressure range of 100 mbar. With a base surface of 31 mm x 40 mm and an insertion height of only 12.9 mm, it can be used even in confined space applications. The compact piezoresistive pressure transmitter based on MEMS technology is suitable for pressure measurement of atmospheric and non-corrosive gases. In addition to differential pressure measurement, these transmitters can also be used for overpressure measurement in the temperature range from -20°C to +70°C.

     The transmitter has two self-locking pressure ports for assembling a 4 mm ID hose and provides an Inter-Integrated Circuit (I2C) digital output with 14-bit resolution. I2C is a standard digital interface for communicating with controls in industrial applications. Additional temperature signal output is also available through the I2C digital interface. The transmitter is equipped with two plug connectors for easy daisy-chaining systems enabling multiple sensors in a single network.

     These sensor systems are ideal for demanding industrial applications such as pressure level measurement, flow control and filter monitoring. Applications include pumps and compressors, pneumatic systems, building management systems, etc. in the Industry 4.0 market.
