(at 25℃, Absolutely flat target under the condition of standard)

OEM: FS≤1m, accuracy can be ±1mm

FS≤2m, accuracy can be ±3mm

FS≤15m, accuracy can be ±0.25% FS

Output signal

Standard: 4-20mA (3 wires)

OEM: 4-20mA(4 wires), 0-20mA, 0-5v, 1-5v

0-10v, 1-10v (both signal can not be customized DC12v)

RS485(MCU protocol as default, Address=01, bps=9600)

4-20mA+RS485; 1-5V+RS485, 1~2NPN

1-10V, 0-10V, 4-20mA(two wire) - Power supply 24VDC can not be OEM

Measuring mode

Standard: Distance mode, the distance of ultrasonic sensor surface to measuring target surface

OEM: Level mode; the distance of level surface to level bottom(the bottom of tank)

NOTE: Ensuring the distance of sensor surface to the level bottom is the actual mounting

height, otherwise might be have installation error.

Working temp.Standard: 0~50℃
OEM: Negative Temp. -10℃,-20℃,-30℃; Positive Temp. 60℃,70℃,80℃
Wiring ModeQuick connect type terminal(can be customized cable outlet about 1m)
InstallationScrew type or sifter clamping ; screw size: M68*2.0mm
Protection classIP65, OEM of IP66, IP67, IP68

Working environment

Normal pressure, non-explosion-proof; non-corrosive environment

OEM: Anti-explosion symbol Exia II AT3 (DC12 V,range≤10m )

The material sensor housing: PTFE for large power sensor

Strong in corrosion resistance


1.When level range ≥15m, equip with other type ultrasonic sensors

2.Users no need to set the address, bps, installation height, so please verify to factory

before ordering

3.For RS485-PC product, users can adjust the parameter by software(the default software)

The max measure range depends on the smooth level surface, so please confirm the real

using environment and level surface when ordering.
