To Ensure Safe Usage

To Ensure Safe Usage
●Avoid dew condensation or freeze, because these transducers are designed for general indoor use.
●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.
●Signal conditioners CDV-900A and instrumentation amplifier WGA-710C with built-in bridge power supply of 10 VDC are available for PDS-A series. In the case of WGA-710C, connection cable N-70 is required.
●Use a series type power supply.
*If dimensions of the pressure connection are desired to change, contact us.

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.
