Description
CYW series ultrasonic level meter can adopt two-wire, three-wire or four-wire technology, and the power supply loop and signal output loop are *** vertical. When the ultrasonic level meter adopts dc 24v power supply, a three-core cable can be used. The negative end of power supply and the negative end of signal output share a core wire. When an ac 220v power supply is used, or when a dc 24v power supply is used, requiring complete isolation of the power supply circuit from the signal output circuit, the ultrasonic level gauge shall use a 4-core cable. Dc or ac power supply, 4~20mADC, high and low switch output.
Application: 1, measure, vacuum pressure flow, liquid level, low table and the proportion of 2, two wire system can reach 30 m 3, four wire amount can reach 40 m 4, 5, 1 mm resolution LCD/LED large screen 6 7, intelligent signal processing technology, equipped with high and low a double relay (only four wire) 8, all plastic anti-corrosion shell (protection level lP67) 9, the structure of the transducer (small range level meter flange installation, the length of the flange to take over the no request) 10, simple button to set parameters (without waiting for container empty or full, No additional remote control) 11. Flexible installation (thread/flange, fixed hole/bracket) 12. Optional ac or dc power supply (4-wire only)
