ALTHEN P6420-57 Pressure Sensor
The ALTHEN P6420-57 is a pressure sensor featuring a two-wire 4-20mA output. Its standard pressure range is from 5 bar to 50 bar, and it can be scaled according to customer requirements.
Based on a four-arm strain gauge bridge fused with a high-purity ceramic diaphragm, the sensor provides high natural output and excellent resistance to chemical corrosion. It is primarily designed for use with concrete slurry and other abrasive fluids, featuring a pore-free, flush sensing diaphragm covered by a flexible polypropylene shield.
The P6420-57 offers a two-wire 4-20mA output proportional to fluid pressure, with other outputs available as options. The sensing element and its associated electronics are housed in a robust stainless steel casing, ensuring durability and reliability in harsh environments.
