80T-150UA

80T-150UA Universal Temperature Probe Instruction Sheet 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.
