OVERVIEW
Oil mix water monitor, suitable medium: oil based liquid.Max working pressure:16bar.Medium temperature 0…100℃.Source: DC24V AC220V.Protection classic IP65. 4~20mA analog+ two way output, brass alloy material, LED digital display ,Use key operation to set menu.
THEORY&STRUCTURE
Device adopts capacitive theory. Capacitive sensor is composed of internal and external electrode (equivalent to two plate of capacitance) and circuit part.When oil mix water or hydrops,due to both dielectric constant have big difference,so the capacitance value composed of internal and external significantly change.Sensor circuit produce a stabe and high frequency square wave,When the capacitance value changes, the square wave frequency changes.After the signal deal to amplify and compare, output corresponding transmit analog quantity alarm signal.
CHARACTERISTICS
No moved elements,free for maintenance,easy to install,one type suitable for various nominal diameter demands.Switch value continue adjustable, very low pressure loss,various output functions optional.Can satisfied different users for the demand of automatic control.With LED digital display,use key to set menu.
APPLICATIONS
Oil mix water signal device used to monitor hydropower station , heat -engine plants and the mix water or hydrops quantity of large pump station oil system .it will give out alarm signal when the oil tank, oil pipeline mixed in water or hydrops,to warning the duty person to check the system in time and make sure to insure generator set operate safely.
