DESCRIPTION

Setra’s Model 231 Multi-Sense Wet-to-Wet differential pressure transducer all-inclusive design provides users with ﬁeld accessible ranging, choice of output and ﬁeld zeroing. Choose from three conﬁgurable Model 231 pressure transducers: 5 up to 50 psid, 10 up to 100 psid, or 25 up to 250 psid. Each Model 231 has 4 unidirectional and 4 bidirectional switch selectable pressure ranges and can be reconﬁgured in the ﬁeld for 0-5 VDC, 1-5 VDC, -0-10 VDC, or 4 to 20 mA output. The Model 231 jumper selectable port swap feature eliminates costly replumbing if the pressure transducer is improperly installed or replaced. An optional LCD display is available for on-site indication of line and differential pressure.

PRESSURE RANGE CODE SELECTOR (IMportant: rEaD BEForE orDErInG)

Examine the pressure application and determine what is the Highest System Line Pressure. Determine what is the Differential Pressure being measured. Find the MAX. Line Pressure in the table on the right that is > to your Highest System Line Pressure. Verify that your DP falls within the selectable ranges in that row. Follow that row to the left and select that range code.

Example: Highest System Line Pressure: 125 psig
