A. handling and installation.
1)Equip the pressure sensor with following our guideline in safety.
We can guarantee the quality of the product by the protective grade(IP) that is a
certificate for preventing from moisture, water or dust etc. If you need further
information, Please refer to catalogue or ask to the main office or agent.
2)Do not drop or shock the sensor.
It may cause a breakdown or malfunction.
3)Do not pull the cable strongly.
It may cause a breakdown or malfunction.
4)Do not insert a sharp-point like a needle into the pressure port.
It may cause a breakdown or malfunction.
5)Do not touch each setting key with a sharp-point.
It may cause a damage to the setting key.
6)Do not touch a diaphragm or a flush diaphragm(F/D)with hands or any
instruments.
It may cause a breakdown or malfunction.
7)Please install the sensor after getting rid of dust ,which remains in the
pressure line, or any
overpressure when you tighten the product.
It may cause a breakdown. Especially, in case of being
pressure line, it may generate beyond rated pressure just to conjoin the pressure port.
8)Please tighten a hexagon head in the pressure port with a wrench when
installing.
It may cause a damage to the product if you tighten other part to install.
9)There will be a possibility of being changed the zero output itself after
equipping the product to the pressure line.
Please arrange the zero out after installment.
B. Connection
1)Do not bend, pull or overload on the cable repeatedly.
It may cause a disconnection.
2)Fix the cable close to the sensor minimizing vibration in a surrounding
quaked place.
It may cause a breakdown or malfunction.
3)Do not operate wiring works while the line is live.
It may cause a breakdown or malfunction.
4)Do not use the same route as a power supply cord and a high tension
wire.
It may cause a breakdown or malfunction owing to noises from the power
supply cord and the high tension wire.
5)Please check electrical insulation.
Digital Pressure Gauge
pressurized materials, which
full of materials in the
PDR250 Users Manual
If electrical insulation occurred, the overvoltage or overcurrent were
applied
malfunction.
6) In case of using a switching power, please ground it to the FG terminal.
C. Use environment
1)Do not use the pressure sensor at the place where there is possibility
of the electrical surge.
If there were an equipment which generated a mass of electric surge or a lightning
surge surrounding a pressure sensor, there would be possibilities of heat deterioration
or destruction of the internal circuit.
2)Do not use the pressure sensor nearby the devices which generate
strong high frequency noise.
It may cause malfunction owing to inpouring the high frequency noises from the
devices which generate strong high frequency noise(a high frequency welding machine,
mass capacity of SCR controls etc.)
3)Be careful not to freeze the pressure materials.
It may cause a breakdown.
4)Please install orifices in front of the pressure port to protect a diaphragm
from a electrical surge. When installation at
water hammer where there is possibility of generating impact pressure.
5)Be careful not to change the surrounding temperature abruptly.
It may cause falling the accuracy slightly.
D. Repair and Inspection
1)Please do the inspection and the repairing the pressure sensor after
shutting the power supply off.
It may cause a breakdown or malfunction.
2)Please do the inspection and the repairing the pressure sensor periodically.
3)When operating the calibration for Zero/Span output, must do with
authorized instruments.
There will be possibilities of malfunction due to the calibration with unauthorized
instruments. Please ask this company how to do.
4)Do not use water or any organic solvent but a dry towel for the
cleaning.
Cleaning with an wetted material, it may cause a breakdown, malfunction or damages
to the surface and a label.
