Capacitive Pressure Transducer

Capacitive Pressure Transducer

(OP)
I'm using a Setra Model 264 Low Differential Pressure Transducer to measure pressure differences in a water manometer. However, I am getting outputs in voltage using a voltmeter and want to know how to convert these voltages to pressure in mm H2O.

RE: Capacitive Pressure Transducer

RTFM.

RE: Capacitive Pressure Transducer

The specified range of the pressure input will have a linear relationship with the specified range of the (voltage/current) output.

Call Kele (USA) 901-382-4300 and ask for tech support. Doesn't matter if you bought it there or not.  They'll walk you through it.

Good on ya,

RE: Capacitive Pressure Transducer

It's quite straight forward.

Need the voltage range and the pressure range. Here's an example:

Assume you are using the standard voltage output of 0 - 5 VDC.

And let's say the range is 0 - 2.5 in. wc.

If you are reading 2 volts on your meter then you would convert as follows:

(2 volts x 2.5 in. wc.)/ 5 VDC = 1 in. wc.

I noticed you asked for mm, so I'll let you do the conversion.
