To Ensure Safe Usage

• Avoid dew condensation or freeze because the transducer is not drip-proof.
• When using for a 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.

Remarks

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