2.9.2 Connecting One or Two Sensors
• The ST95 Uplink Client is designed to be installed di-
rectly to specific sensor assemblies and equipment that
conforms to industry 4–20mA standards.
• It is the customers responsibility for sensor selection
and compatibility with these standards.
• When the uplink is connected to multiple devices the
total loop resistance must be calculated and understood.
• The ST95 Uplink Client itself has a resistance of 350
Ohms at 21 Volts.
• Refer to the System Control Drawings for a picture of
the installation. Route the sensor cable to the Tank Sen-
sor and select the appropriate wire colors to connect to
the Sensor per the Termination Table.
• When routing the cable down the side of a tank, secure
it using cable ties or other fasteners as required.
• Refer to ST95 Family wiring guides for better illustration
(see previous pages).
• Wire the Sensor positive and negative wires to the col-
ors marked Circuit 1, 21V+ (Orange) and Circuit 1, Input
(Yellow) respectively.
• For the second sensor, wire the sensor positive and
negative wires to the colors marked Circuit 2, 21V+
(Green) and Circuit 2, Input (White) respectively.
NOTE: The customer will need to supply any additional cabling as
appropriate within safety limits.

2.10 Mounting the Electronics Housing

Determine the best place to mount the Electronics/
Housing one of the optional mounting kits. The ST95
can be mounted using the included universal mounts
or a sensors specific mount. The ST95 kit contains
both Hose Clamps and a Pipe Clamp to hold the ST95.
Select the combination of parts suited to your space.
Use the 2" Brass spacer to extend the pipe or Hose
clamp away from the mounting surface if needed. The
hose clamps can be used to secure the mount to a pole
if desired. Both clamps can be connected for a larger
diameter pole. For wall mount you can screw one of the
clamps directly to it. Once you have selected the loca-
tion, mount the ST95 and route the cable from the tank
to that location and secure it appropriately.
The sensor specific mount (if ordered) can be mounted
to the sensor electronics housing.
