Model 109SS Temperature Probe

1. General

The –L portion of this probe’s model number indicates the probe has a user­specified lead length. For readability purposes, the probe will be referred to as
the 109SS throughout this document.

The 109SS consists of a thermistor encased in a stainless-steel sheath. The
rugged stainless-steel sheath protects the thermistor allowing the 109SS to be
buried or submerged in harsh, corrosive environments. It also has a fast time
response. This probe measures temperature from -40°C to +70°C. The
thermistor can survive temperatures up to 100°C, but the overmolded joint and
cable should not be exposed to temperatures greater than +70°C (see Figure
1-1).

The 109SS probe is typically used with the CR200-series, CR800, CR850,
CR1000, and CR3000 dataloggers which have a special instruction for
measuring it. The probe can also be measured with other Campbell Scientific
dataloggers using generic measurement instructions.

The 109SS ships with:

compound was chosen for its resistance to temperature extremes,
moisture, and UV degradation. However, this jacket will
support combustion in air. It is rated as slow burning when
tested according to U.L. 94 H.B. and will pass FMVSS302.
Local fire codes may preclude its use inside buildings.
