HD350 series | Ultrasonic Level Meter｜HD350-A / HD353-A
[Measurement Equipment [ Level meters ]]
●For screen mode can be selected
●Large display is adopted for HD353-A (Display size : 50 x 25mm, 49% larger than HD350-A)●Mask function
Unnecessary signal can be eliminated from the received signal by manually.
Echo signal from existing structure positioned between sensor and target cause interference. Mask function removes these unnecessary echo effectively.●Interface
Three interface methods are prepared for remote operation.
1) RS-485 (MODBUS protocol)
2) 4-20 ｍA current output
3) Contact points (relay output)
