Keller Company Differential Pressure Sensor Series 33X
High-precision differential pressure sensor with RS485 digital output - capable of liquid/liquid differential pressure measurement!
The differential pressure sensor 33X achieves an extremely high accuracy of 0.05% full scale (FS) in the temperature range of 10 to 40°C through a mathematical correction method. In addition to a digital RS485 interface, analog current or voltage outputs are also available. 【Features】 • Piezo-resistive differential pressure sensor capable of measuring liquid/liquid differential pressure • Accuracy of ±0.05 %FS in the temperature range of 10 to 40°C • Standard dual outputs of digital RS485 and analog output (Analog output options include 4–20 mA, 0–5 V, 0–10 V, and 0.1–2.5 V) • Analog output range can be changed via digital RS485 • Line pressure: up to 60MPa • Excellent long-term stability • Correction technology using a mathematical model to provide accurate pressure values
