The Bosch Rexroth HM 20-2X/315-C-K35 (R901342029) is a high-precision pressure transducer designed for dynamic pressure control in hydraulic systems. This model boasts an analog output of 4-20 mA, suitable for a pressure range up to 315 bar. It features a rapid signal rise time of less than 10 ms, ensuring timely responses in dynamic applications. The robust construction includes all media-contacting components made from stainless steel, enhancing the durability and longevity of the transducer in challenging environments. The HM 20-2X/315-C-K35 is engineered with a thin-film measuring cell that delivers exceptional measurement accuracy of less than ±0.5% FS. Its superior overload and bursting behavior make it reliable for safety-critical applications. The unit comes with a G1/4 hydraulic connection and includes a throttle element within the pressure channel to stabilize readings. Equipped with an M12, A-coded electrical connector, this device adheres to EN standards, ensuring compatibility and ease of integration into existing systems. It operates on a supply voltage of 9-32 VDC and has a weight of approximately 0.4 kg. The NBR seals are compatible with hydraulic fluids such as HL, HLP, HFC, and Nitrogen up to 350 bar. This transducer is notable for its operational safety features including high bursting pressure resistance and protection against reversed polarity, overvoltage, and short circuits. It offers an accuracy class of 0.5 with excellent non-repeatability below 0.1%. The wide operating temperature range from -40 to +125°C allows for versatile use across various climatic conditions. Additionally, the HM 20-2X/315-C-K35 holds certifications such as CE and UL along with compliance with RoHS directives for environmental considerations. It also has marine approval from DNV GL suitable for maritime applications. This component series X transducer can handle maximum operating pressures up to 630 bar across its different pressure ratings variants, further demonstrating its adaptability to diverse industrial requirements.
