1.1.1.2. RF Long-Range Ambient Sen-
sors
The RF Long-Range Ambient Sensor
improves on the 150 feet transmitter-to-receiver
maximum distance of the other internal & exter-
nal sensor models. The cylindrical enclosure
holds a “whip” antenna capable of transmitting
to receivers as far away as 200 feet.
Like the shorter-range sensors described in
Section 1.2.1.1., there are both internal and
external models of the long-range sensors, both
with either clean switch or digital defrost termi-
nation inputs. Table 1-2 lists each long-range
sensor model.
1.1.1.3. RF Product Simulator
The RF Product Simulator (P/N 809-3548)
mimics the thermal characteristics of product
within refrigerated cases or freezers. Tempera-
ture readings from product simulators can be
used to verify product remains within acceptable
food safety levels.
