Model 109SS Temperature Probe 1. General The –L portion of this probe’s m odel number indicat es the probe has a user- specified lead length. For readab ility purposes, the pr obe will be referred to as the 109SS throughout this docum ent. The 109SS consists of a thermistor encas ed in a stainless-steel sheath.
Model 109SS Temperature Probe 1.1 Specifications Temperature Range: -40° to +70°C Survival Range: -50° to +100°C (thermistor); -50°C to +70°C (overmolded joint and cable) Thermistor Interchangeability Tolerance: Temperature Tolerance -40°C ± 0.
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 negligi ble error (Figure 2-1).
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.
Model 109SS Temperature Probe The datalogger is programme d using eith er CRBasic or Edlog. Dataloggers that use CRBasic include our CR 200-series, CR800, CR850, CR1000, CR3000, CR5000, and CR9000(X); see Section 5.1. Dataloggers that use Edlog include our CR10, CR 10(X), CR23X, and CR7; refer to Secti on 5.
