Accubar SDI-12 Barometric Pressure Sensor Operations & Maintenance Manual Rev-B 30 Nov 2017

6. Installation
The ACCUBAR
®
will return accurate and reliable pressure data in any mounting position. We
recommend, however, mounting the sensor with the connector and cable gland pointing downward.
This will prevent any moisture from following the cable or tubing down to the ACCUBAR
®
sensor.
The ACCUBAR
®
mounts to a panel or surface through two holes that are accessible under the sensor
cover. The through-holes accommodate #4, #6, M3, or M3.5 hardware. In addition, the unit is supplied
with optional external mounting feet. The external mounting feet support #8, #10, #12, M4, or M5
hardware.
The ACCUBAR
®
barometric pressure fitting is a hose barb for a 3/16" ID tubing.
If the supplied cable is to be replaced with an installation specific one, then it should be noted that the
terminal block accommodates wire sizes from 30 AWG to 14 AWG or up to 1.5 mm2. The recommended
length of bare wire is 0.22" or 5.5 mm. The cable gland accepts cables with an O.D. anywhere between
0.12” and 0.26” (3
-6.5 mm).
