Bosch Rexroth Pressure Sensor HM20-2X/400-C-K35

Pressure SensorA Pressure Transducer is a device or apparatus capable of sensing pressure signals and converting them into usable electrical signals according to a certain pattern.

Pressure sensors are typically composed of pressure-sensitive elements and a signal processing unit. Depending on the different types of test pressure, pressure sensors can be categorized into gauge pressure sensors.SensorDifferential Pressure Sensors and Absolute Pressure Sensors.

SensorA transducer/sensor is a detection device capable of sensing measured information and converting the sensed information into electrical signals or other required forms of information according to certain rules, to meet the requirements for information transmission, processing, storage, display, recording, and control.

The characteristics of sensors include miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. They are the primary components for achieving automatic detection and control. The presence and development of sensors give objects tactile, gustatory, and olfactory senses, gradually bringing them to life. They are typically categorized based on their basic sensing functions into thermosensitive elements, photosensitive elements, gas-sensitive elements, force-sensitive elements, magnetic-sensitive elements, humidity-sensitive elements, sound-sensitive elements, radiation-sensitive elements, color-sensitive elements, and taste-sensitive elements, among others.
