Abstract
Abstract A temperature transmitter includes a temperature probe, such as an RTD or thermocouple, and a transmitter housing. Electrical circuitry in the transmitter housing is adapted for coupling to the temperature probe and providing an output related to a sensed temperature. The temperature housing has a first side for coupling to the temperature probe and a second side which carried a plurality of electrical connections electrically connected to the circuitry carried in the transmitter housing. An elongated recess on an outer surface of the first side of the transmitter housing channels electrical wiring which connects to the temperature probe in a direction away from the temperature probe and toward the electrical connections carried on the second side of the transmitter housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
148 words
A temperature transmitter, comprising: a temperature probe for sensing a temperature, said probe having probe wires connected to a temperature responsive element; electrical circuitry coupled to the probe wires and providing an output related to sensed temperature; a housing which contains the electrical circuitry and has a first side coupled to the temperature probe and a second side carrying a plurality of electrical terminals connected to the electrical circuitry; and an elongated recess in an outer surface of the first side of the housing adjacent the probe and extending in a direction away from the probe, the elongated recess receiving the probe wires and channeling the probe wires along the outer surface in a direction away from the probe and to the plurality of electrical terminals on the second side of the housing the coupling between the electrical circuitry and the probe wires being through the electrical terminals.
