4-pin socket for connection of the Surface Temperature Transducer
MM 0035. The electrical connections for this socket are similar to Air
Temp. MM 0034 and thus this socket can also be used to connect a
second
Air Temperature Transducer in place of the Surface Tempera-
ture Transducer. This
enables simultaneous measurement of air tem-
perature in two places to be obtained (for example at two different
heights).
6-pin
socket for connection of the Air Velocity Transducer MM 0038 to
the Type 1213.
12-pin
socket for connection of the Radiant Temperature Asymmetry
Transducer MM 0036 to the Type 1213.
8-pin socket for connection of the Humidity Transducer MM 0037 to
the Type 1213.
Two BNC
sockets accepting plug JP 0035 for connection of an X-Y
Recorder, Level Recorder, etc. The outputs and voltage scalings are
given in
Table 2.1.
