8.1.5 Barometric Reference Specifications
Accuracy: 0.01% of reading. Uncertainties include all pressure effects, temperature effects over the
calibrated range and calibration stability for 365 days after re-zeroing.
Pressure Range: The standard Barometric Reference Transducer is calibrated from 8 to 17 psia.
Resolution: 6 digits.
8.2 External Transducers (CPT6100 and CPT6180)
The CPT6100 and CPT6180 are stand alone Digital Pressure Transducers that can be purchased
separately and connected to the remote transducer port on the back of the CPA2501. The CPT6100 and
CPT6180 have their own data sheets and manuals.
8.2.1 External Pressure Transducer Connection Cable
A shielded ribbon cable is required to connect an external transducer and can be supplied with or without
an external Transducer. The part number is: 4060090001.
8.3 Rack Mount Kit
The CPA2501 can be supplied with a single or dual 19” rack mount kit.
Dual Rack Mount Single Rack Mount
8.4 Fittings
A variety of fittings are available at the time of order on transducers with a max range of ≤ 6015 psi (410
bar), or the CPA2501 can be ordered without adaptor fittings. Available fittings are shown in Section 9.2 -
Spare Parts.
8.5 Remote Calibration
A remote calibration sled, power supply, cable and software are available to calibrate the optional baro-
metric reference. A cable / power supply and software are available to remotely calibrate the internal
transducers outside of the CPA2501. In both cases a PC with a serial connection is required. Both kits are
supplied with an instruction manual.
