Keller Company Pressure Sensor Series 23SX
High-precision and low-cost pressure sensor
The pressure sensor series 23SX is a high-precision pressure sensor that compensates for temperature dependence and non-linearity through mathematical correction within the microcontroller. It comes standard with two outputs: digital RS485 and analog output via a D/A converter. With a fully welded structure that does not use internal seals, it can be used in a wide range of applications. Only stainless steel comes into contact with the measured medium. 【Features】 - Standard equipped with two outputs: digital RS485 and analog output - The analog output can be range-changed via digital RS485 - Achieves excellent long-term stability - Fully welded structure without internal seals 【Technology】 - Piezo-resistive pressure sensor - Correction technology using a mathematical model to provide accurate pressure values - Based on the technology used in the 33X series, achieving the highest level of accuracy
