Keller Company High-Precision Pressure Sensor Series 20SX

High-precision pressure sensor in sensor head type, ideal for OEM applications!

The 20SX series pressure sensor head with screw connection is specially designed and optimized for OEM applications, achieving the highest level of accuracy, excellent long-term stability, and high pressure resistance. Features that many pressure sensor manufacturers offer only as options are standard in Keller products. The 20SX series is characterized by a compact, fully welded design and high-precision, range-changeable digital correction electronics. Accuracy errors, including thermal effects, are minimized or corrected using mathematical models. As a result, it achieves the highest accuracy and an extremely narrow Total Error Band (TEB). The introduction of the 20SX series has further expanded OEM products. 【Features】 • High accuracy of ±0.05% FS • Standard dual outputs of digital RS485 and analog output • Analog output can be range-changed via digital RS485 • Excellent long-term stability 【Technology】 • Piezo-resistive pressure sensor • Fully welded structure without internal seals • Correction technology using mathematical models to provide accurate pressure values • Based on the technology used in the 33X series, achieving the highest level of accuracy.
