Differential pressure transducer 20Kpa for level measurement


Hello, we are interested in differential pressure transducer and the range should be 1 to 2 PSI, we don’t need the sensors giving the direct out put of 4-20mA. We have our own circuit to convert the signal to extracted square root and give the 4-20 mA.  SS120 series is more suitable for our application, in this your range start from 35 KPa, where we are looking something lower than this, even 20 KPa will do.

SS120 series piezoresistive silicon differential pressure sensor, working follows the principle of piezoresistive effect. the main part is a high stability diffused silicon chip. It utilizes silicone oil to transfer pressure from 316L stainless steel diaphragm to sensing element. All stainless steel integrated structure, high stability, good reliability, high static pressure, is widely used in to measure liquid and gas differential pressure.
