PRECAUTIONS FOR SAFE USE

PRECAUTIONS FOR CORRECT USE

Observe the following precautions to ensure safe operation. 

· Places subject to exposure to water, oil, or chemicals

· Dispose of the Fine Differential Pressure Sensor as industrial waste.

· Do not subject the product to a shock by an accident such as dropping the 

product. Doing so may cause damage to or malfunction of the product. To 

prevent damage from dropping the product, secure screws to the wall 

surface. If strong impact is applied to the product, stop use of the product.

 Applicable standards

                                                   (EN/IEC

 

61326-1

 

Table 2)

1. Avoid installing the product in the following places: 

· Places exceeded the rated ambient temperature

· Places exposed to extreme temperature changes (prevent condensation.)

· Places exceeded the rated RH level

· Places subject to corrosive or flammable gases

· Places subject to mist, droplets, coarse particles, fiber, salt, metal dust, or 

large amount of particles

· Places subject to direct shock or vibration

· Places subject to direct sunlight

· Places subject to exposure to water, oil, or chemicals

· Places subject to strong magnetic field or electric field

2. Wiring

· Lay the product cable away from any high-voltage cable or power line.  If 

laid in the same conduit or duct, induction noise from them may cause 

malfunction or breakdown of the product.

· Do not connect the product to a controller other than ZN-DPX

□□

-S. Do 

not hold this sensor alone with the controller mounted (where the controller 

mounted).

3. Fine differential pressure measurement

· To conduct measurement, fine air flow will be required. To conduct 

accurate measurement, shorten the air tube length to be connected as much 

as possible and do not bend or fold the air tube. Connecting a bent air tube 

or air tube with a length of more than 1 m may cause failure of proper 

measurement.

· When installing the air tube on the wall, be careful for vibrations not to 

be transmitted to the air tube. Failure to do so may cause failure of 

proper measurement.

4. Others

· Do not apply pressure that exceeds the rated pressure. Doing so may 

cause malfunction or damage of the product.

* For the precision under a rated environment, an offset less than 0.1 Pa/year may 

occur.

Secure the product on the wall, etc. using screw holes.

M3x8 screws are provided.

Insert the air tube into the pressure inlet. There are inscriptions at the high pressure 

side ( 

 Hi) and low pressure side ( 

 Lo) at the top of the pressure inlet. Properly 

connect air tubes according to a subject to be measured. When pressure at the high 

pressure side is high, the measured value is positive, and when pressure at the low 

pressure side is high, the measured value is negative.

Mounting

Insert the connector (male) of the product into the sensor head connector (female) of 

the controller.

Install the product according to the mounting method described in the Instruction 

Sheet of the controller.

Be sure to contact OMRON for the calibration of the differential pressure sensor head.

When sending the sensor head to OMRON, take care to prevent foreign substances 

from entering into the sensor head.
