general description

1. ur series insert type magnetic floating ball liquid level transmitter

floating ball with magnetic steel ring rises and falls as change of liquid level resulting in open and close of reed pipe inside main tube of the transmitter and transforming liquid level into resistance output. in connection with intellectual digit display instrument produced by us, remote test, alarm and control of liquid level could be realized.

1. ub series insert type magnetic floating ball liquid level transmitter

on the basis of ur series liquid level transmitter, through special module process (electronic amplifier), resistance signal output is transformed into 4~20ma signal of double wire system, which could be directly connected with ddz-ⅲ electromotive unit instrument for realization of remote test, alarm and control of liquid level, or connected with intellectual digit display instrument produced by us.
insert type magnetic floating ball liquid level transmitter is used for measuring liquid level of media in container under pressure (or open) in chemical industry, power, papermaking, shipbuilding, environment protection, and foodstuff industry, etc. it is much more easier and electric to test liquid level of underground trough, pond, and water container for high-rise building. it is made of corrosion-resistant stainless steel and suitable for place with combustible or explosive.
working theory
there are a group of reed pipes and precision resistance in main tube of insert type magnetic floating ball liquid level transmitter. the floating ball with magnetic steel ring rises and falls as liquid level change with buoyancy resulting in close (connection) one by one reed pipes on the liquid surface in main tube of the transmitter under magnetic field effect. accordingly, resistance value of return circuit changes transforming into electric current output through special module.
