Overview
Standard transducers are available as replacements for
BEC, BCU, and RMCC systems.
Table 10 lists the part numbers for the 100, 200, and
500 lb. pressure transducers along with pressure/voltage
ranges for each CPC standard pressure transducer type.
Description
Computer Process Controls pressure transducer is a
pressure sensing device that converts pressure readings to
a proportional electrical signal between one and six volts
DC. The transducer is designed with a 1/4” flare fitting for
connection to a standard access fitting. If the fitting is con-
figured with a Schrader valve, installation of a shut-off
valve is not required. If the access fitting is not configured
with a Schrader valve, install a shut-off valve between the
transducer and the system. The standard pressure transduc-
er is not compatible with ammonia however, the standard
pressure transducer may be subjected to a vacuum without
damage.
Standard pressure transducers should be mounted in a
vertical position (pressure port down) above crank case
oil level to prevent accumulation of oil in the transducer
port.
