Product Details
NOHKEN tuning fork level switch SG21/SG31/SG510
Manufacturer: NOHKEN (Nengyan)
Working principle: SG type is a tuning fork type liquid level gauge. The detection section contains two piezoelectric components, one of which vibrates the tuning fork of the detection section,
The other one detects the frequency of vibration and acts 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 of the tested object is fully immersed, the vibration frequency will change. Based on the frequency variation, detect the presence of liquid
None. According to the principle of tuning fork resonance, a piezoelectric crystal located at the root of the tuning fork vibrates, and the vibration frequency is detected by the tuning fork at the other end
Come, but when there is liquid, the vibration frequency will change to detect the presence or absence of the liquid. ）
Main purpose: Suitable for saving operating space, high and low level alarms of high-pressure vessels, environments requiring high-precision devices, and water supply to pipelines
Pump protection.
Main features: Good durability, no need for adjustment or maintenance, AC/DC power supply available (2-wire type), * high withstand voltage up to 10MPa.
Main parameters:
Wiring: 2-wire type, DC 3-wire type, relay contact output type
Measurement object: Liquid (specific gravity: 0.6~2.0, viscosity: 0.2~10000CP)
Operating temperature: SG21/31/41 type: -40~+150 ℃, SG51 type: -10~+150 ℃
Structure: IP66/IP67
Material of the liquid receiving part: SUS316L
Shell Material: Glass Fiber Reinforced Nylon (PA66 30% GF)
Work Confirmation Window: Synthetic Resin (PMMA)
Please refer to our company catalog for specific parameters.
