Setting resolution 0.01 kPa.D {1 mmH2O.D} Detecting clogging of filter The clogging of a filter can be reliably detected by the differential pressure, indicating the time for filter replacement. Repeatability Within ±1 % F.S. Lo Hi MODE FUNCTIONS Bright display and easy key operation Versatile control with two output modes Three bright red 7-segment LEDs, 12 mm 0.472 in high, are incorporated in the compact body. They can be clearly read not only in a dark place, but also, in a welllit place. Further, initialization or pressure settings can be easily done with key operation while looking at the display. 1 Hysteresis mode The lower threshold value and the upper threshold value establish the hysteresis of the comparative output. Pressure unit selectable The pressure unit can be selected from “kPa” and “mmH2O” according to your requirement. Further, during measurement, the pressure unit can be recognized at a glance from the pressure unit indicator. kPa mmH2O When the pressure unit is changed, threshold values and the measured pressure value are automatically converted. 2 Window comparator mode The comparative outputs can be made ON or OFF by a pressure within the limits set by the upper and the lower threshold levels. VARIETIES Analog current output type: DP-M2A DP-M2A is incorporated also with the analog current output (4 to 20 mA). Hence, it is ideally suited for real time monitoring and multi-point control in combination with an analog controller (ultra-compact digital panel controller CA2 series). Micro-differential Pressure High-precision Digital Pressure Sensor DP-M SERIES ORDER GUIDE 752 FIBER SENSORS LASER SENSORS Appearance Rated pressure range Model No. Standard Type Pressure port Output MICRO PHOTOELECTRIC SENSORS DP-M2 With analog current output AREA SENSORS ø4.6 mm ø0.181 in resin pipe 0 to 2.00 kPa.D {0 to 204 mmH2O.D} PHOTOELECTRIC SENSORS NPN open-collector transistor DP-M2A LIGHT CURTAINS / SAFETY COMPONENTS PRESSURE / FLOW SENSORS INDUCTIVE PROXIMITY SENSORS PARTICULAR USE SENSORS OPTIONS Designation SENSOR OPTIONS Model No. Description Sensor mounting bracket MS-PE-1 L-shaped bracket [Two M3 (length 8 mm 0.315 in) screws with washers are attached.] Panel mounting bracket MS-PE-2 It can be used for mounting on a panel (1 to 3.2 mm 0.039 to 0.126 in thick).

PRECAUTIONS FOR PROPER USE Refer to p.1472 for general precautions. • Never use this product as a sensing device for personnel protection. • In case of using sensing devices for personnel protection, use products which meet laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country. • The DP-M series is designed for use with non-corrosive gas. It cannot be used for liquid or corrosive gas. Mounting • The displayed value may vary by 1 digit (0.01 kPa.D {1 mmH2O.D}) maximum depending on whether the sensor is installed vertically or horizontally. • A sensor mounting bracket MS-PE-1 (optional) may be used. When mounting the sensor with the sensor mounting M3 (length 8 mm 0.315 in) screw with washers bracket, the (Accessory for MS-PE-1) tightening torque should be mounting bracket 0.5 N·m or Sensor MS-PE-1 (Optional) less. Operation • If setting is impossible even with pressing the MODE key, verify whether the key-protect function is enabled. Please note that pressing down on the MODE key for an extended moment (for 4 sec. or more) will enable the key-protect function as soon as the key is released. The key-protect function is set when the display shows and is released when the display shows . • If using the window comparator mode, lower threshold value (M1) and upper threshold value (M2) should be set with a difference of 3 digits (0.03 kPa.D {3 mmH2O.D}) or more. No output will be possible with a 0 to 2 digits difference.

MACHINE VISION SYSTEMS UV CURING SYSTEMS • Use flexible tubes (silicone tube etc.) that can fit the pressure ports, ø4.6 mm ø0.181 in in diameter. The tubes should cover more than half the length of the pressure ports. Lo H i Recommended tube Selection Guide • TYGON® tube R-3603, size: internal dia 4 mm 0.157 in, external dia 6 mm 0.236 in, manufactured by Saint-Gobain K. K. Contact the manufacturer for details of the recommended product. Pressure/ Digital Display Flow Pressure Lo-port Flexible tube (Silicone tube etc.) Conditions in use for CE conformity • The DP-M series is a CE conformity product complying with EMC Directive. The harmonized standard with regard to immunity that applies to this product is EN 61000-6-2 and the following condition must be met to conform to that standard. Conditions • The sensor should be connected less than 10 m 32.808 ft from the power supply. • The signal line to connect with this sensor should be less than 30 m 98.425 ft. Pressure/ Head-separated DP-100 Pressure Hi-port Fix tubes on ports securely Notes: 1) TYGON is registered trademarks of Saint-Gobain K. K. 2) Ensure that excessive pressure is not applied to the pressure ports. Since this sensor is designed for detecting small pressures, if excessive pressure or shock is applied to the pressure ports, the diaphragm (pressure sensing device) in the sensor may get damaged. 3) Please do not compress the tube. If the tube is compressed, pressure exceeding the rated value may be generated, damaging the diaphragm (pressure sensing device).
