Pressure Sensors / Flow Sensors

Q-1
When using DP2 vacuum pressure type, "－－－" is displayed even though there was no pressure. Normally, it is supposed to be displayed as "0 (zero)", but it is displayed as error. I have been using this sensor for a while already. Why does such an error occur just recently?
Q-2
What is the slew rate of analog output of sensor head DPH-A27 for DP5 series?
Q-3
Will pressure sensor PLX-2L get damaged if negative pressure is imposed for a second?
Q-4
Please tell me how to release auto-reference of DP3.
Q-5
With the DP2 series, I would like to use window comparator mode on the output mode. Are both outputs based on the same logic?
Q-6
When using compound pressure type of DP4/DP5 series, I want to set ?45 or less kPa as ON; -30 or more kPa as OFF. How can we set the magnitude relation of the pressure setting to the reverse when vacuum pressure is used on compound pressure type?
Q-7
When using DP2 series, is there a way to read the outputs of both the value above the upper limit value and the one below the lower limit value separately?
Q-8
After conducting zero-adjustment during the installation of DP2-20Z, by how much will an error of display occur at atmospheric pressure?
Q-9
In the input/output circuit diagram of DP3 series, there is a pull-up resistor drawn in dotted line between auto reference input and + V. Is this needed?
Q-10
DP-M2Z has a HI side of pressure port and a LO side. Is high-pressure decided to be on the HI?
Q-11
Is it okay to apply a reverse pressure against rated pressure on pressure sensors such as DP2 and DP3?
Q-12
Can I use multiple sensors PLX to connect to a controller PAD?
Q-13
If I use a vacuum pump to draw out high vacuum on a pressure sensor of vacuum pressure type, why is that the sensor does not display -101.3 kPa?
Q-14
What does "1 digit" mean as noted in the catalog?
Q-15
Can a pressure sensor be used in air or water?
Q-16
How to set up a pressure sensor?
Q-17
What is non-corrosive gas?
Q-18
Can nitrogen be detected?
Q-19
What is the amount of leakage in a pressure sensor? (Pneumatic type)
Q-20
Sensor PLX and controller PAD are in use within the rated pressure range. However, PAD display is shown as "－－－". Does this mean the applied pressure has overcome the rated pressure range?
Q-21
Can calibration be performed on pressure sensors or flow sensors?
Q-22
Why are the digital display value and the actual pressure value of a pressure sensor slightly different? Zero-adjustment is performed on the pressure sensor.
