III. INSTALLATION
Plug the RTD Temperature Probe (DVP-94Y) into the “probe” receptacle, the Thermo Container
into the “Thermosel” receptacle, and a strip chart recorder (if used) into the recorder jack. The
rear panel will appear as follows in Figure 1.

III.1 Probe
The probe is a 100 ohm precision platinum RTD (Resistance Temperature Detector) probe
(Brookfield Part No. DVP-94Y) which is plugged into the probe port on the rear panel.
Note : The RTD Probe must be plugged into the Model 75 Controller and the RTD Probe end
must be inserted into the Thermo Container before power is turned on. An error message
will be displayed if the Model 75 Controller is turned on and the RTD Probe is not in-
stalled.
III.2 Recorder
The recorder jack provides a signal to a recording device (the HT-88Y cable is provided for this
service) such as a strip chart recorder. The full scale recorder output signal range is from 0 to 4 V
for the Thermosel. The temperature can be obtained from the output potential (in mV) as follows:
Brookfield Engineering Labs., Inc. Page 4 Manuel No. M/94-203-D89
The 0 to 4 volt output corresponds to a temperature range of -100
°
C (-148
°
F) to 300
°
C (572
°
F).
Realistically, temperatures in the Thermosel will typically be above ambient. Therefore, output
voltages will generally range from slightly less than 2 volts (<100
°
C) to the full 4 volts (300
°
C).
