MOUNTING TRANSDUCERS ON A 1012 TRANSDUCER TEST BLOCK
1. Identify the side of the simulator that applies to the transducers under test. Rotate the clamping brac-
ket as required to mount transducers on the test surface.
2. Using a coupling compound (preferably CC-102), mount the transducers on the pipe simulator as
shown above. Slide each transducer until it presses against the pin-stop. Use the clamping screws to
hold the transducers in place.
3. Connect transducer cables between each transducer and the meter connectors for the channel
under test. The Up and Down orientation is not important.
Troubleshooting With Transducer Test Blocks
To resolve an apparent system malfunction, you have to determine whether the problem is due to equip-
ment failure or an application condition. Our 1012 and 996 Transducer Test Blocks allow you to bench
test the flow computer, transducers and their cables. If the system operates properly using the test block,
then focus on application conditions as the source of the problem. Series A and B 1011 transducers use
the 1012TB-1 Test Block and series C and D use the 1012TB-2 Test Block. At the present time, neither
one support the 1011 High Precision transducers.
The 996PSP-pipe simulator allows you to test a Sitrans F 1010 flowmeter and 991 transducers from size
0 to size 3. Note that although our flowmeter operates with our 991 size 4 and 5 transducers, testing of
these sizes with our flowmeter is not currently supported.
2.11.10 USING THE 1012TB-1 AND 2 TEST BLOCKS
The 1012TB-1 and 1012TB-2 test blocks provide two test surfaces. Each surface supports a specific
transducer size. For example, one surface of the 1010TB-1 supports Size “A” transducers and the other
supports Size “B” transducers. The 1012 pipe simulators include two labels, one on each side-plate. The
labels identify the transducer size, data to be entered, and the surface to be used with the specific
transducer size. See drawing on next page.
