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.

Operating Notes

The following paragraphs are intended to familiarize the operator with

the 80T-150UA. The operator should read these paragraphs before

attempting to operate the probe.

Probe Limitations

The 80T-150UA probe is constructed of a highly durable plastic and is

suitable for measuring the temperature of liquids, gases, and solid

surfaces up to 150 °C. When measuring temperature, observe the

following precautions to prevent damage to the probe:

1. Do not expose the probe end (probe tip plus about 2 inches of the

probe body) to temperatures exceeding +150 °C (+302 °F). The

remainder of the probe body should not be exposed to temperatures

above +70 °C (+160 °F).

2. Do not expose the probe end (probe tip plus about 2 inches of the

probe body) to temperatures below -50 °C (-58 °F). The remainder

of the probe body should not be exposed to temperatures below

-40 °C (-40 °F).

3. For liquid measurements, recommended applications range from

water, lubricants, and fuels to most solvents. Liquids as shallow as

1.27 cm (0.5 inch) can be measured since the temperature sensor is

inch the probe tip. XWWarning

To avoid electrical shock, do not use this instrument when

voltages exceeding 60 V dc or 30 V ac rms (42.4 V peak )

are present. The probe tip is electrically connected to the

output terminals.

WCaution

Long-term exposure of the probe to corrosive

environments will result in pitting and deterioration of the

aluminum probe tip. If equipment is used in a manner not

specified by the manufacturer, the protection provided by

the equipment may be impaired.

Error Sources

When the probe tip is applied to a solid surface, it draws or sinks heat

from the surface. Therefore, if the measured surface has a low mass

(e.g., a transistor case), the indicated temperature may be lower than

the actual temperature.

Similarly, a steady-state error or gradient exists between the measured

surface and the sensing device in the probe tip. This is due to the flow of

heat from the measurement surface to the probe body. The effect of the

steady-state error increases as the differential between ambient and

surface temperature increases.

To determine the actual surface temperature of a device, both the heat-

sinking and steady-state errors must be considered. The correction curve

given in Figure 1 approximates the effect of both error sources on TO-3,

TO-5, and TO-18 transistor cases.
