Testing the Pressure Transducer Circuit

BNCJHT01.C06 0000191880 C.2 F.3 A.9 1/2/20 1:16 PM Released

The pressure transducer (illustrated in

Figure 11: Pressure Transducer Component Identification,

) outputs a microvolt-level signal that increases proportionally according to the pressure

in the plastic tube. The instrumentation amplifier magnifies this signal by a factor of 1000 for the
microprocessor. Because only very sensitive voltmeters are capable of reading a signal of less
than one millivolt, better results are available by measuring the output voltage from the instru-
mentation amplifier. This procedure is described below:

CAUTION:

Electrocution and Electrical Burn Hazards —

Electric box doors—Op-

erating the machine with any electric box door unlocked can expose high
voltage conductors inside the box.

1. Locate the instrumentation amplifier on the processor board. This is a small integrated circuit

chip with eight leads in socket IC20, near the pressure transducer.

2. Set your digital voltmeter to read a maximum of 5 volts DC. The output of this component,

even when failed, will not exceed 5 VDC.

3. Locate pin 6 on the instrumentation amplifier. Note the notch in one end of the amplifier chip.

If the board is oriented so the notch on the chip is at the left side of the chip, then pin 1 is the
leftmost pin on the bottom row. Count pins counterclockwise to pin 6. If the orientation of the
board is maintained (pin 1 at the lower left), then pin 6 will be the second chip from the right
on the top row. This is the amplifier output pin.

4. Put the positive lead from your voltmeter on pin 6 of the amplifier chip, and the negative lead

to a reliable electronic ground. Pin 5 (rightmost pin on top row) of the amplifier chip provides
a suitable ground.

The output voltage read on the meter should be approximately 0.085 volts per inch of water in
the machine cylinder. That is, if the machine is filled to a level of 4 inches (10 cm), the voltage
measured between pins 5 and 6 of a functioning amplifier will be about 0.33 volts.

NOTE:

If your voltmeter is capable of reading microvolts, the transducer can be tested

without the effect of the instrumentation amplifier. The notched pin on the transducer is
pin 1 (ground). The reference voltage of slightly less than 1.5 VDC is applied to pin 3.
Pins 2, 3, and 4 will all read the reference voltage relative to pin 1. The output voltage be-
tween pins 2 and 4 should equal approximately 0.085 millivolt per inch of water.

If the voltage is lower than expected, first check for leaks in the plastic tube connected to the
pressure transducer. If no leaks are found, or if the voltage is significantly higher than expected,
replace the processor board.
