The Bosch Rexroth HM 20-2X/400-C-K35 (R901342033) is a high-performance pressure transducer designed for monitoring and controlling hydraulic pressures in demanding applications. This transducer is capable of converting measured pressure into a normalized, linear electrical output signal, ensuring accurate and reliable pressure readings. It features a robust thin film measuring cell and all components that come into contact with media are constructed from durable stainless steel, enhancing its longevity and resistance to harsh conditions. The HM 20-2X/400-C-K35 offers operational safety through its high bursting pressure capacity and built-in protections against reversed polarity, overvoltage, and short circuits. Its accuracy class is 0.5, with an impressive non-repeatability of less than 0.1%, ensuring precise measurements every time. The device can operate within a wide temperature range from -40 to +125 degrees Celsius, making it suitable for use in various environments. This model has received marine approval from DNVGL for all variants with current output, indicating its suitability for maritime applications. It belongs to component series X and can handle maximum operating pressures up to 400 bar. The available pressure ratings include 100, 160, 250, 315, 400, 600, and up to 1000 bar. Additionally, the HM 20-2X/400-C-K35 is cULus listed, confirming its compliance with North American safety standards. With its comprehensive range of features and certifications, the Bosch Rexroth HM 20-2X/400-C-K35 pressure transducer is an essential component for hydraulic systems requiring precise pressure monitoring and control across various industries and applications.
Unpacked Weight: 0.0605 kg
Pressure transducers are used to monitor and control hydraulic pressures. They transform the measured pressure into a normalized, linear, electrical output signal.
