Level switches

Our level switches have been developed and calibrated for level detection with a series of models such as Capacitance type, Vibration type, Impedance type, etc.
The level switches deliver a contact output (On and Off) with detecting the level of objects to be measured.
Level switches with simple construction and more cost-effective than level transmitters does not deliver the signal of a middle value, thus a number of level switches are required for the case of obtaining the signals at several points such as upper, middle and lower levels.

Capacitive Level switch

Model NQH
(Non-explosion-proof type)

Model NSH
(Intrinsically safe construction)
(Flameproof construction)

Capacitance type level switches are available with a series of models such as Straight-rod probe type, Flat probe type, Wire type, In-pipeline type and etc. which are mainly suitable for measuring the insulating material.

Net capacitive Level switch

Model DLS
(Non-explosion-proof type)

DITECH’s proprietary net capacitive level switch is immune to the influences of electrical conductivity variations and offers the highest sensitivity among electronic level switches.

Impedance type Level switch

Model NQS
(Non-explosion-proof type)

Model NSS
(Intrinsically safe construction)

This models are designed to fully meet the demands to measure the various material from conducting substance to insulating material.

Guard type Level switch

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

Model NSS-G
(Intrinsically safe construction)

The guard type level switch was developed by combining DITECH’s two proprietary techniques, Impedance & guard measurement systems which means it will not be affected by the adhering substance.

Vibrating Level switch for sediment

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

Model STA-D
(Intrinsically safe construction)

This level switch is suitable for water storage tanks and excavated-material tanks in order to detect the level of underwater (seawater) settling sand or slurry.

Level switch for molten metals

Model DIM-LS・Model IPM-LS
(Non-explosion-proof type)

At ultrahigh temperatures, conventional capacitive level switches cannot measure the level of good conductors. DITECH’s proprietary level switch for molten metals has been developed to make this possible.

Conductive Level switch

Model NQS-CL・Model DR-L
(Non-explosion-proof type)

Model NSS-CL
(Intrinsically safe construction)

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

Blower-equipped Level switch

Model NQH-BL・Model DTA-BL
(Non-explosion-proof type)

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

Model STA-BL
(Intrinsically safe construction)

This blower-equipped level switch blows out a small amount of air (nitrogen) through a port at the tip or side of the probe to keep the powder from solidifying while detecting the level of the powder.
