To Ensure Safe Usage

• Avoid dew condensation or freeze, because thess transducers are designed for general indoor use.
• 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.
* If dimensions of the pressure connection are desired to change, contact us.

Remarks

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