Page 7: General Information
The datalogger measures the signal differentially and scales it to the excitation current. This current is detected by the datalogger by measuring the voltage drop across a 100-Ohm precision resistor such as Campbell Scientific’s part #7977 in series with the black excitation wire. CS400/CS405 transducers are vented so that changes in barometric pressure are compensated for in the measurement. -
Page 8: Installation
Before operation, visually confirm the vent tube is open. The vent tube opening must terminate inside a desiccated enclosure or a Campbell Scientific DES2 desiccant case. The desiccant must be changed regularly. -
Page 9: Transient Protection
Using the CS400/CS405 Submersible Pressure Transducer with Campbell Scientific Dataloggers 3.3 Transient Protection Campbell Scientific recommends transient surge protection for sensors installed in lightning prone areas. No lightning protection is capable of withstanding a direct hit, but surge protectors afford a degree of protection for near misses. -

Wiring diagram for a CS400/CS405 and a DES-2 connected to a BDR301. 3.8 PST3/8 The PST3/8 has a #7977 built-in. Figure 3-2 shows the wiring for a CS400/CS405 and a DES-1 which can be connected to the PST3/8. -
Page 11: Using Short Cut
Short Cut’s (Windows or DOS) Help for more detail on using the offset. Older versions of Short Cut for DOS required the transducer’s sensitivity be entered in the units of mV. Visit Campbell Scientific’s web site (www.campbellsci.com) or talk to an applications engineer to receive your free copy of the latest Short Cut release. - Page 12 Using the CS400/CS405 Submersible Pressure Transducer with Campbell Scientific Dataloggers Factory calibration: Each CS400/CS405 transducer is shipped with a calibration report specific to that unit. The report specifies calibration conditions and actual data reflecting the transducer's static accuracy and thermal characteristics. Newer calibration reports from KPSI include a slope figure near the bottom of the page that may make the following calculations unnecessary.

Using the CS400/CS405 Submersible Pressure Transducer with Campbell Scientific Dataloggers Field calibration hints: Make the two depths as far apart vertically as practical within the pressure range of the transducer to minimize the slope error. Repeated observations will increase your accuracy. -
