PrimeLog Input Connections
The connectors on PrimeLog include logos for identification. The following 
sections describe the connections and show the corresponding logos. 
WARNING: Due to the operational requirements of depth 
transducers, never immerse the connector in or expose it to water. The 
vent tube from the transducer sensor terminates at the connector and 
must be open to the atmosphere to sense pressure in vented gauge 
mode. If water enters the vent tube, the sensor may become 
operationally impaired or irreparably damaged. This damage is not 
covered by the ADS warranty. 
Digital Inputs
Typically, connecting the sensor correctly ensures the logger provides the 
necessary power. However, for sensors requiring an external power source, 
refer to Interfacing on page 18 for more information. 
If the logger starts before the sensor is connected, a malfunction will not 
occur. However, the logger will record only zero values until the sensor is 
connected. 
Internal Pressure Transducer
(no logo)
Loggers equipped with an internal pressure transducer have a male quick-
release connector mounted on the logger end cap. 
This integrated pressure transducer is available in a wide range of sensitivities, 
from 44 to 363 psi. Pressures of more than 150% of its range may damage the 
transducer. Subjecting the transducer to shocks may change the zero point 
calibration of the transducer; however, calibrating the logger can compensate 
for this offset. 
A hose with male and female connectors is available to connect the logger to 
the pressure monitoring point. 
Avoid pressure shock when connecting to the transducer. This can damage or 
destroy the sensing diaphragm.
