Product Description
The P101 ultrasonic level meter is a compact measurement device containing an ultrasonic transmitter and an electronic module. The level meter transmits a series of ultrasonic pulses that spread towards the level surface. The transmitter recuperates reflected acoustic waves that are subsequently processed in the electronic module. Based on the period during which the individual pulses spread towards the level and back, this period is averaged by the electronics that performs temperature compensation and subsequently a conversion to an output current 4 -20 mA, voltage 0 - 10 V or output RS-485 Modbus.
Thanks to the contactless measuring principle, the P101 ultrasonic level sensor is suitable for continuous measurement or limit level switch sensing of liquids, waste water, sludge, suspensions, adhesives, resins in various open and closed vessels, sumps, open channels and drains.
Setting is carried out either using two buttons or a magnetic pen or by
remote setting in case of Modbus RTU output. The device is equipped with optical indication of its state (RUN) and the setting
process (STATE). It is manufactured in designs for normal (N) and explosive atmospheres (Xi).
