German DR SCHETTER sensor, DR SCHETTER model, DR SCHETTER price

DR SCHETTER sensor is a sensor that measures the air flow drawn into the engine. For electronically controlled gasoline injection engines, to obtain the optimal mixture concentration under various operating conditions, it is necessary to accurately measure the amount of air drawn into the engine at every instant, using this as the main basis for the ECU to calculate (control) the fuel injection quantity. If the air flow sensor or wiring fails, the ECU will not receive the correct intake air signal, preventing normal control of the fuel injection quantity, which will cause the mixture to be too rich or too lean, resulting in abnormal engine operation.

DR SCHETTER 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. Submersible static pressure 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 fluid statics is an important application of pressure sensors. The use of special cables with ventilation ducts 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.

DR SCHETTER sensor features

1) Since the output of the liquid level depends only on 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) Since the photoelectric level sensor probe is relatively compact, it can be installed separately in narrow spaces, making it 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.

DR SCHETTER 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.
