Overview
CPC supplies Eclipse

Pressure Transducers for use in
some refrigeration control systems. All 100, 200, and 500
PSIG pressure transducers ordered for use with RMCC sys-
tems or shipped with new RMCC systems will be Eclipse

transducers.The part numbers and hardware specifications
are listed in Table 8. Software setup is described below.
Description
The Eclipse

pressure transducer is a pressure-sensing
device that converts pressure readings to a proportional
electrical signal between 0.5 - 4.5 volts DC. The transducer
is designed with a 1/8” male national pipe thread (NPT) fit-
ting for connection to a standard access fitting.
If the access fitting is configured with a Schrader valve,
this fitting will have to be replaced with a standard 1/8”
NPT female fitting. Each transducer is supplied with 20
feet of cable for connection to a 16AI input board. Table 9-
shows pressure/voltage ranges for each transducer.
Do NOT connect an Eclipse

Pressure Transducer to
a 12V supply. Eclipse

transducers are rated for 5V
DC.
