4. Sensor Hook-up and Example Diagrams

There are three options available when ordering the A150. The first option
includes a stripped and tinned continuation cable. The length of this cable is
specified when ordering the A150.

The second option includes a PWENC connector, allowing the A150 to be
attached to prewired enclosures.

The third option includes a connector to attach the A150 to the CWS900
wireless sensor interface. The CWS900 completes the connection to the
datalogger through a wireless sensor network.

Figure 3 shows the pin-out of the CWS900 connector. Take care that the
sensor wires attached to the A150 correspond to the correct pins as shown in
the diagram.
