Temperature Sensor (Gauge): Testing and Inspection
Fig. 45 Thermal Transmitter Inspection
Connect an ohmmeter to the thermal transmitter as shown in Fig. 45. With water temperature at 140°F, resistance should be approximately 70-90
ohms. With water temperature at 212°F, resistance should be approximately 21-24 ohms.
