German RUMMEL sensor RUMMEL model RUMMEL price

RUMMEL sensors are used in robots to mimic tactile functions. Touch is an important sensory function when humans come into direct contact with the external environment. Developing tactile sensors that meet requirements is one of the key technologies in robot development. With the development of microelectronics and the emergence of various organic materials, a variety of development plans for tactile sensors have been proposed, but most are currently in the laboratory stage, with few reaching commercialization. Tactile sensors can be roughly divided by function into contact sensors, force-torque sensors, pressure sensors, and slip sensors.

RUMMEL sensor introduction

Divided into two categories: one is contact type, including single-flange static pressure/dual-flange differential pressure level transmitters, float level transmitters, magnetic level transmitters, submersible level transmitters, electric internal float level transmitters, electric displacer level transmitters, capacitive level transmitters, magnetostrictive level transmitters, servo level transmitters, etc. The second category is non-contact type, including ultrasonic level transmitters, radar level transmitters, etc. Static pressure submersible level transmitters (level gauges) are suitable for level measurement of various media in systems and industries such as petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, and environmental protection. The compact structure, simple calibration, and flexible installation methods provide convenience for users. Standard signal output methods such as 4～20mA, 0～5v, 0～10mA can be selected by users according to needs. Measuring liquid level using the principle of hydrostatics is an important application of pressure sensors. The use of special cables with ventilation conduits in the middle and specialized sealing technology ensures the watertightness of the sensor while allowing the reference pressure chamber to communicate with ambient pressure, thereby ensuring high accuracy and high stability of the measurement.

RUMMEL sensor features

1) Since the output of the liquid level is only related to whether the photoelectric probe contacts the liquid surface, and is unrelated to other characteristics of the medium such as temperature, pressure, density, electricity, etc., the photoelectric level sensor offers accurate detection and high repeatability; fast response speed, very precise liquid level control, and can be directly installed and used without calibration. 2) Due to the relatively compact size of the photoelectric level sensor probe, it can be installed separately in narrow spaces, suitable for use in special tanks or containers. In addition, multiple photoelectric probes can be installed on one measuring body to create multi-point level sensors and controllers. 3) Since all components inside the sensor are encapsulated with resin, there are no mechanical moving parts inside the sensor, so the photoelectric level sensor has high reliability, long life, and is maintenance-free.

RUMMEL sensor applications

Widely used in water plants, refineries, chemical plants, glass factories, sewage treatment plants, high-rise water supply systems, reservoirs, rivers, oceans, etc., for the measurement and control of static and dynamic liquid levels in water supply pools, distribution pools, water treatment pools, wells, water tanks, storage tanks, oil wells, oil tanks, oil pools, and various liquids.
