Current output 4...20 mA
(PT24xx)
P = system pressure, MEW = final value of the measuring range
In the measuring range the output signal is between 4 and 20 mA.
If the system pressure is above or below the measuring range, the analogue output
behaves, without achieving the accuracy, as follows:
• System pressure above the measuring range: 20...25 mA.
• System pressure below the measuring range: 4...3 mA.
5 Installation
Before installing and removing the unit: make sure that no pressure is
applied to the system.
►
Insert the unit in a ¼-18 NPT process connection.
►
Tighten firmly. Recommended tightening torque: max. 50 Nm.
Depends on lubrication, seal and pressure load!
