Measurements:

 

 

 

 

 

 

 

 

 

 

 

1

Measure voltage between terminal

 

 

V DC

Voltage should be in the range 14 to 33 V DC.

 

5 and 6

 

 

 

Check power supply.

 

 

 

 

 

 

 

 

 

 

 

2

Measure ripple voltage between

 

 

V AC

Voltage must not exceed 2 V AC. Check power

 

terminal 5 and 6

 

 

 

supply.

 

 

 

 

 

 

 

 

 

 

 

3

Measure sensor excitation voltage

 

 

 

V DC

Voltage should be in the range 3.0 to 6.2 V DC

 

between terminal 7 and 10

 

 

 

 

 

 

 

 

 

 

 

 

 

4

Measure sensor excitation voltage

 

 

mV DC

Voltage should be in the range -15 to 100 mV DC

 

between terminal 8 and 9

 

 

 

 

 

 

 

 

 

 

 

 

5

Measure current in supply lead to

 

 

 

 

 

Current should be in the range 4 to 20 mA and the

 

terminal 5

 

 

 

mA DC

same value as measured in point 6. If not the

 

 

 

 

 

 

 

 

 

amplifier may be defect.

6

Measure current in supply lead to

 

 

 

 

 

Current should be in the range 4 to 20 mA and the

 

terminal 6

 

 

 

mA DC

same value as measured in point 5. If not the

 

 

 

 

 

 

 

 

 

amplifier may be defect.

7

Measure sensor resistance with

 

 

 

 

 

If the resistance measured is less that 1 M Ohm the

 

sensor cable unconnected

 

 

 

 

 

sensor is defect.

 

 

 

Terminal 7 to cable shield

 

 

M Ohm

 

 

 

 

 

Terminal 8 to cable shield

 

 

M Ohm

 

 

 

 

 

Terminal 9 to cable shield

 

 

M Ohm

 

 

 

 

 

Terminal 10 to cable shield

 

 

M Ohm

 

 

 

 

8

Measure sensor bridge resistance

 

 

 

 

 

If the resistance measured is less than 1 K Ohm or

 

with sensor cable unconnected

 

 

 

 

 

greater that 50 K Ohm the sensor is defect.

Visual inspection of the transmitter:

 

 

 

 

 

 

 

 

 

 

Is the cable damaged?

 

 

 

 

 

 

 

 

 

Are there sharp bends on the cable?

 

 

 

 

 

 

 

 

 

Are there moisture/liquids in the breather tube?

 

 

 

 

 

Is the diaphragm damaged?
