Product Overview

P499 Series Electronic Pressure Transducers Product/Technical Bulletin 5
3. Measure the current between the transducer
SUPPLY (red wire) and COMMON (black wire) with
a multimeter set to measure milliamperes (mA).
This is the measured output current.
4. Compare the ideal output current (Step 2) to the
measured output current (Step 3). If the current
from measured output current differs greatly from
the ideal output current, replace the transducer.
Note: It is normal for the transducer reading to differ
somewhat from pressure gauge readings due to
multimeter and gauge tolerances, and other factors.
Repair Information
Do not attempt to repair or recalibrate the P499 Series
Electronic Pressure Transducers. If repair or
replacement is needed, contact your nearest
Johnson Controls/PENN authorized distributor or sales
representative.
Ordering
Figure 6 is a type identification matrix that identifies all
the potential P499 Series electronic pressure
transducer types. Not all combinations in Figure 6 are
manufactured and available. Contact your local
Johnson Controls/PENN representative for more
information on options available for high-volume
models with specific application requirements.
Table 3 through Table 5 list the features on standard
P499 transducer models available through most
Johnson Controls/PENN authorized distributors.
See Table 2 for information on wire harnesses.
