1.6 Temperature Probe
The Temperature Probe [1910-852] is an
RTD type. The probe itself is 1/4” diameter 18” long, stainless steel,
with an aluminum connector head. It screws into a 1/2” NPT port and is provided with a cable which plugs into
the J3 connector at the bottom of the Control Box. The operational range for OFS 2000CW is -40° to +932°F [-
40° to +500°C].

Figure 1.10 Activator Heater
The Activator Heater [1910-850] is rated at 1500W @ 120V. It
is recommended that a dedicated branch circuit controlled with
a 15A breaker be provided. The heater element is 3/4” in
diameter 36” long with an INCONEL sheath and threaded to
fit a 3/4” NPT port. The active portion of the heating element
begins 12” from the base and extends the remaining 24” to the
end of the rod. The connector head is Class I, Div. 1 & 2,
Groups C,D rated. The heater element is equipped with a K-
type thermocouple. For OFS 2000CW application a current-
sensing circuit is used. The connecting cable (provided) plugs
into the J4 connector at the bottom of the Control Box.
