Since thissensor is designed for detecting small pressures, if excessive pressure or shockis applied to the pressure ports, the diaphragm (pressure sensing device) in thesensor may get damaged.Please do not compress the tube. If the tube is compressed, pressure exceedingthe rated value may be generated, damaging the diaphragm (pressure sensingdevice).Pressure Hi-portFix tubes on ports securelyPressure Lo-port Flexible tubes(silicone tube etc.)࣭TYGON tube, size: internal dia 4mm, external dia 6mm, madeby SAINT-GOBAIN.Not goodەەApply higher pressure to the Hi-port and lower pressure to theLo-port.Use flexible tubes (silicone tube etc.) that can fit the pressureports, ȭ4.6mm in diameter. The tubes should cover more thanhalf the length of the pressure ports.ەەەNever use this product as a sensing device forpersonnel protection.In case of using sensing devices for personnel protec-tion, use products which meet laws and standards,such as OSHA, ANSI or IEC etc., for personnelprotection applicable in each region or country.In case this sensor is used within Japan, SI unitmust be used since use of pressure units in Japanis restricted to SI units.WARNINGCAUTIONS2ەەەەەەەەەەەەەەەThis product has been developed / produced for industrial useonly.Use within the rated pressure range.Make sure that the power supply is off while wiring.Take care that wrong wiring will damage the sensor.Verify that the supply voltage variation is within the rating.If power is supplied from a commercial switching regulator,ensure that the frame ground (F.G.) terminal of the power supplyis connected to an actual ground.In case noise generating equipment (switching regulator, invertermotor, etc.) is used in the vicinity of this sensor, connect theframe ground (F.G.) terminal of the equipment to an actualground.Do not use during the initial transient time (0.5 sec.) after thepower supply is switched on.Do not run the wires together with high-voltage lines or powerlines or put them in the same raceway. This can cause malfunc-tion due to induction.Avoid dust, dirt, and steam.Take care that the sensor does not come in contact with water,oil, grease, organic solvents, such as, thinner etc., or strongacid, and alkaline.Do not insert wires, etc, into the pressure port. The diaphragm(pressure sensing device) will get damaged and correct opera-tion shall not be maintained.Do not operate the keys with pointed or sharp objects.Make sure that stress by forcible bend or pulling is not applieddirectly to the sensor cable joint.Extension up to total 100m is possible with 0.3mm 2 , or more,cable. However, in case of using this product as a CE conformityproduct, the power wire connected to this product must be within10m.DP-M series is designed for use with non-corrosive gas. It cannotbe used for liquid or corrosive gas.LED Display࣭ Digital Differential Pressure SensorDP-M Series For use outside JapanINSTRUCTION MANUAL
