Detectors for liquid

Our detectors for liquid such as Conductive switch, oil film detector, etc. have been developed and calibrated for detecting the conductive changes, floating oil film in the water, etc.
Two kinds of detectors are available, one is type to deliver a contact output (On and Off) and other type to deliver a integrated signal continuously to detect at certain setting point.

Conductive switch

Model NQS-CS・Model DR
(Non-explosion-proof type)

Model NSS-CS
(Intrinsically safe construction)

This device has been developed to detect the conductivity of substances that are difficult to measure such as high-viscosity liquids.

μm-class ultrathin oil film detector

Model QBS-OFμ
(Non-explosion-proof type)

Model NSB-OFμ
(Intrinsically safe construction)

This is the μm-class ultrathin oil film detector to detect floating oil films in facilities such as water channels, closed water channels and wastewater pits.

mm-class oil film detector

Model NQH-OFm
(Non-explosion-proof type)

Model NSH-OFm
(Intrinsically safe construction)

This device is designed to detect floating oil films in facilities such as water channels, closed water channels and wastewater pits.

Drain pipe leakage detector

Model NQS-LE
(Non-explosion-proof type)

Model NSS-LE
(Intrinsically safe construction)

The drain pipe leakage detector is designed to detect liquid leaks from drain pipes and pipe joints.

Moisture detector for quenching oil

Model D-Q
(Non-explosion-proof type)

Moisture in an insulating liquid noticeably reduces the liquid’s breakdown voltage. The moisture detector for quenching oil draws on this property to detect moisture in quenching oil.

Foam detecting switch

Model NQH-FO・Model NQS-FO
(Non-explosion-proof type)

Model NSH-FO
(Intrinsically safe construction)
(Flameproof construction)

Model NSS-FO
(Intrinsically safe construction)

This switch is designed to detect the soap foam, beer foam, latex foam, etc.
