Differential pressure transmitter Relative, absolute and differential pressure transmitter Type 664 The pressure transmitter type 664 is designed for low pressure measurements in air and neutral gases environments. The type 664 is based on silicon technology with good accuracy and long term performance characteristics. The compact housing dimensions of the type 664 makes suitable for applications where the size plays an important role, it is also provided with I2C digital output additionally to analogue and ratiometric outputs. + The output signal is temperature compensated (from -20 up to +70 ºC), linearized and amplified + Mounting on PCB possible + Robust design Huba Control Type 664 | Technical data subject to change | Edition 09/2020
