Description

3 Blinks (contd.)

- Disconnect the White wire in the sensor cable from terminal 6.

- Set the meter to read DC current (mA)

- Connect the black lead from the meter to terminal 6

(TRANSDUCER INPUT)

- Connect the red lead from the meter to the White wire in the

sensor cable.

- The meter will display the output of the sensor. If functioning

properly, the output of the sensor will be between 4mA and

20mA depending on the pressure in the system. Refer to the

chart below to determine the sensor feedback at various pressures.

The following formula gives the transducer output based on applied

pressure:

Output Current = Output Current Range x System Pressure + 4mA

Pressure Range

Where:

• Output Current is the transducer output

• Output Current Range is the maximum output signal of the

transducer minus the minimum output signal of the transducer. In

this case:

Output Current Range = 20mA – 4mA, or 16mA

• Pressure Range is the pressure that corresponds to the maximum

output signal. For a 300 PSI transducer the Pressure Range =

300 PSI – 0 PSI = 300 PSI

• System Pressure is the system pressure as read on the pressure

gauge.
