Other Information:
Thermistor: BetaTherm - Micro-BetaCHIP Probe 10K3MCD1 0.018"
diameter, 10Kohms at 25 C
Probe:
stainless steel sheath 0.063 inch (0.16 cm) diameter, 2.3 inch (5.84 cm) length
overmolded joint 0.40 inch (1.02 cm) diameter, 1.67 inch (4.24 cm) length
Cable: Santoprene 0.220 inch diameter
Cable/probe connection: "ATUM" heat shrink, "Macromelt" overmolded joint
Weight: 0.2 lbs/10 1/2 ft cable
The black outer jacket of the cable is Santoprene
®
rubber. This
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.
