The UB200-12GM-E4-V1 is an ultrasonic level sensor manufactured by Pepperl & Fuchs. It is a straight look-through device, mounted to the surface of a tank, with a range of 15÷200mm. It provides an NPN/NO/NC output, up to 30 mA. This part is suitable for detecting liquid levels in tanks, regardless of size, shape, material or color. It uses an ultrasonic pulse to measure the distance of the object in front of the sensor and can be used in process control, batching, filling level and overflow protection applications.
