Analog Retransmit 1 and 2
One of the optional features often specified with environmental chambers is the circular chart recorder. The
chart recorder is a graphing device used to record chamber data such as temperature, humidity and
pressure over time. An example of a Tenney Chamber with a circular chart recorder is shown below.
Note that the Synergy Nano includes built in Logging features that can often eliminate the need for a
conventional chart recorder.
The Synergy Nano features two analog signals called Analog Retransmit 1 and 2 that can output setpoints,
actual process data and internal PID values. The outputs can either be graphed on the chart recorder or, in
some equipment; the PID output values can be used to control external steam valve (heat), chilled water
(cool) or LN2 liquid nitrogen outputs.
The following section will guide you through the setup for graphing and for custom external heat and cool
systems.
