Introduction

The Model 80T-150UA Universal Temperature Probe is a self-contained
temperature-to-voltage converter. The probe is designed to provide a
direct temperature reading when it is connected to any high impedance
DMM that is capable of 1 mV resolution and at least a 300-count full
scale readout capability. Output is 1 mV per degree (Celsius or
Fahrenheit). Two switch-selected temperature output scalings are
provided: -50 to +150

C or -58 to +302

F. The probe will stand off 60 V

dc or 30 V ac rms (42.4 V peak).

The unit is housed in two separate but attached assemblies: a
temperature probe and a temperature-to-voltage converter. The probe
contains the temperature-sensing element and is electrically connected to
the temperature-to-voltage converter through a 46-inch cable. A three-
position switch on the converter acts as a power switch and is used for
selecting Celsius or Fahrenheit scaling for the output. Two banana plugs
with standard 0.75-inch spacing are provided for connecting the 80T-
150UA to the DMM.

Operating power for the 80T-150UA is derived from a standard 9 V
battery. Typically, an alkaline battery provides more than 600 hours of
continuous operation before replacement is necessary. An OFF switch is
provided on the temperature-to-voltage converter to allow battery
conservation when the unit is not in use. In addition, the OFF position of
the power switch allows the battery condition to be determined via the
external DMM.

Temperature is measured by exposing the probe tip directly to the
material to be measured (non-corrosive liquid, gas, or solid). A direct
temperature reading is displayed on the DMM.
