Dimensions
To Ensure Safe Usage
High-carrier-based dynamic strain amplifier DPM-912,913 or 952 may not satisfy the specified rated output insome rare case.
Use dynamic strain amplifier DPM-911,951, signal conditioner CDV-900A or request us to
calibrate the transducer in combination with the strain amplifier.
Remarks
(Note 1) Copper alloy is used for liquid-contacting part.
Avoid measuring corrosive liquid or gas.
(Note 2) An epoxy adhesive is used to assemble the liquid-contacting part.
Therefore, avoid using the sensor to measure organic solvents (Toluene, ketone, etc.)
(Note 3) It should not be used under high temperature and high humidity environments for a long time.
(Note 4) It should not be used under water.
