14 CPT6010 Operating Instructions
Digital Pressure Transducer
CPT6010
The pressure to be measured is applied to the 1/4 inch NPT fitting. A 10-32 tapped opening on the
opposite end is used as the reference port for gauge pressure. This port is normally left open to
atmosphere, but it can be connected to another source for a reference pressure.
Use either Loctite® Hydraulic Sealant or fresh teflon tape on the threads of the male pipe fittings
when making up pressure connections. The integrity of the seal to the pressure port is important
since even microscopic leaks can cause errors in pressure measurements.
!
Caution
Do not install by grabbing the case and turning it with a wrench or pliers.
Use the wrench flats near the pipe threads. Wrench size is 7/8 inch.
5.6 Electrical Connections
5.6.1 Connector J1 Wiring
Power and signals are applied to J1, a circular 6 pin male connector. A positive power supply
voltage is supplied to pin A, and ground (power and signal common) is connected to pin B. The
CPT6010 is protected against power input reversal. A mating connector (Bendix #PT06E-10-6S
SR) is shipped with the transducer. Wiring between the host and J1 is described by Figures 5.6.2
and 5.6.3.
5.6.2 RS-232 Operation
For RS-232 serial port operation, connect the CPT6010 to the host computer per Figure 5.6.2 No-
tice that the host TRANSMIT line is connected to the CPT6010 RECEIVE line (TX to RX), and vice
versa. One limitation of the RS-232 bus is that a host can support only one instrument. See section
5.6.3, RS-485 Operation, for multiple CPT6010 operation.
Note: Connectors are female, shown from the wired end.
