To Ensure Safe Usage

● Avoid dew condensation or freeze because the transducer is not drip-proof.
● If using as a gage pressure meter, apply pressure to the HIGH side, and open the LOW side to the atmosphere.
● For atmospheric observation, prepare piping to prevent rainwater from entering the pressure inlet.
● When using the bridge power supply of a strain amplifier, use a model (CDV-900A, WGA-710C)which supports 10 VDC.
● The suitable power supply is a series regulator type which generates less noise than the switching type.

Remarks

(Note 1) Use the transducer with general air
(Note 2) If water or any other liquid enters the low side, the transducer gets out of order.
