FAQ

Water level sensor

How to install it.

See the diagram below.
*The dimensions of the mounting part in the diagram below are for reference only, and should be used after considering the amount of O-ring compression, compression ratio, etc.

Is it possible to directly pressurize the liquid?

Yes. It can receive pressure.

Can it be used for pressure media other than water or hot water?

Please contact us for availability.

How much kPa of pressure can be applied?

The pressure resistance is up to 980kPa, but please use it within the rated range and in an environment where impact pressure such as water hammer is not applied.

What happens if the power supply voltage fluctuates?

There is almost no output fluctuation within our recommended power supply voltage (11 to 16V).

What is full scale (%FS)?

Refers to the output span voltage. When showing error and accuracy, it is indicated as a percentage of full scale.

What will happen if a pressure higher than the maximum load pressure is applied?

Offset voltage deviation occurs. In the worst case, the pressure sensor chip may be destroyed.

Is the output signal affected by atmospheric variations?

Gauge type pressure sensors detect differential pressure against atmospheric pressure. Therefore, the output of the pressure sensor is not affected by everyday fluctuations in atmospheric pressure.
* Accurate pressure detection cannot be performed if the atmospheric pressure inlet provided on the side of the pressure sensor package is blocked.

Are there any oil leaks?

If sudden negative pressure is applied repeatedly, some oil may leak out, but since the purpose is to protect the sensor chip, there is no functional problem as long as there is enough oil in the sensor chip.

Will there be any effect on the output if bubbles intervene when measuring water pressure?

Accurate water pressure cannot be transmitted to the sensor chip, which may lead to output errors.

Is there a recommended standard for O-rings to be used during installation?

Please use JIS standard, P-6 size.

Which is the size of the mounting screw?

Assuming M4 size.

Is it possible to use pressure ranges, output voltages, and power supply voltages that are not in the lineup?

The pressure range, output voltage range, and power supply voltage range can be customized, so please feel free to contact us.

Is it possible to detect the water level while submerging?

It is not a waterproof type. Please use it in air.

What is the upper limit of water temperature?

Accuracy is guaranteed up to 50°C. It is possible to use more than that, but it will be out of the temperature compensation range.

What is the detection medium?

The detection medium of the water level sensor is assumed to be “domestic water”
