Bestech Australia provides a wide range of products including sensors, transducers, signal conditioners, controllers and displays. They supply the PDA/PDB series of miniature pressure gauges from TML, Japan. These pressure transducers measure 6.5mm in diameter and are 1mm thick. They are water proofed for daily ordinary use and use a scratch resistant Teflon-covered cable. These pressure gauges are protected with a rating of IP67.
The measuring range of these pressure gauges is from 200 kPa to 3 MPa. Rated output is 1 mV/V and non-linearity is within 1%. The sensor can withstand temperatures of -20 to 70 degrees (no icing). The difference between these two models lies in their cable connection, with the sensor arrangement different relative to the cable. These transducers are used mainly for civil engineering applications.
