Product Details
NOHKEN Japan Nengyan tuning fork type liquid level gauge SG21-20
Manufacturer: NOHKEN (Nengyan)
Working Principle:
SG type is a tuning fork type liquid level gauge.
The detection section contains two piezoelectric components, one for vibrating the tuning fork of the detection section, and the other for detecting the frequency of the vibration, acting as a pickup. When the fork shaped part is in the air, it will vibrate at a certain frequency, but if the fork shaped part is immersed in liquid, the vibration frequency will change. Based on the frequency variation, detect the presence or absence of liquid.
Main parameters:
Wiring: Relay contact output type
Measurement object: Liquid (specific gravity: 0.6~2.0, viscosity: 0.2~10000cP)
Work instruction: ON: light on OFF: light off (1HZ) Fault: flashing (3HZ) Short circuit/overload: flashing (1/4HZ)
Delay: 0.3, 1, 3, 10, 30 seconds (switch on/off)
Working position: 13.5mm ± 1mm from the front end (measuring no water, can be installed horizontally or vertically)
Switch deviation: about 2mm (measured without water)
Wiring: 2 power lines, contact signal lines
Power supply: 24~240V AC ± 10% or 24~54V DC ± 10%
Current consumption: 6mA (when the sensor is turned off)
Surrounding temperature: -40~+80 ℃
Operating temperature: -40~+150 ℃
Operating pressure: -25kPa~10MPa
Structure: IP66/IP67
Material of the liquid receiving part: SUS316L
Shell Material: Glass Fiber Reinforced Nylon (PA66 30% GF)
Installation size: R1 '
