Model 109SS Temperature Probe 1. General The –L portion of this probe’s m odel number i ndicates the probe has a user- specified lead length. For readab ility purposes, the pro b e will be referred to as the 109SS throughout this docum ent. The 109SS consists of a thermistor encas ed in a stainless-steel sheath. The rugged stainless-steel sheat[...]

Model 109SS Temperature Probe 1.1 Specifications Temperature Range: -40° to +70°C Survival Range: -50° to +100°C (thermist or); -50°C to +70°C (overm olded joint and cable) Thermistor Interchangeability Tolerance: Temperature Tolerance -40°C ± 0.6°C 0°C ± 0.38°C 25°C ± 0.1°C 50°C ± 0.3°C 70°C ± 0.45°C Time Constant: Fluid τ St[...]

Model 109SS Temperature Probe 2. Accuracy The overall probe accuracy is a combinati on of the thermi stor's interchangeability specification and the accuracy of the bri dge resistor. The Steinhart and Hart equation used to calculate temperature has a negl igible error (Figure 2-1). In a "worst case" the errors add to an accuracy of ?[...]

Model 109SS Temperature Probe 3. Installation and Wiring 3.1 Burial The 109SS is suitable for shallow burial onl y. It should be placed horizontally at the desired depth to avoid thermal conduction from the surface to the thermistor. Placem ent of the cable in side a rugged conduit may be advisable for long cable runs, especially in locations subje[...]
