Keller Company Differential Pressure Sensor Series 23X
High-precision differential pressure sensor with RS485 digital output (±0.1%). Liquid/liquid differential pressure measurement is also possible!
The differential pressure transmitter PD-23X is a high-precision differential pressure sensor that can also handle liquid/liquid differential pressure. A single silicon diaphragm integrated inside directly measures the pressure difference applied from both ports. This design allows for the measurement of small pressure differences under very high line pressures. It achieves an extremely high accuracy of 0.1% full scale (FS) using correction technology based on a mathematical model that provides accurate pressure values. 【Features】 - ±0.1% FS accuracy - Capable of measuring liquid/liquid differential pressure - Standard dual outputs of digital RS485 and analog output - Analog output can be range-adjusted via digital RS485 - Temperature range of -20 to 125℃ - High line pressure (up to 60 MPa) - Excellent long-term stability 【Technology】 - Piezo-resistive pressure sensor - Correction technology using a mathematical model for accurate pressure values
