Note: 1. Lead Wire (Compensating Conductor)
• Standard (−20°C to 70°C):
10
10
Fully vinyl-covered with seven 0.3-dia. conductors (0.5 mm
thick) and external dimensions of 3.2 × 5.0.
• Heat Resistive (0°C to 150°C):
900°C
Fully glass-wool-covered with seven 0.3-dia. conductors
(0.5 mm thick) with external shield of stainless steel and
external dimensions of 2.9 × 4.6
The heat-resistive lead wires cannot be used in locations
exposed to water or other liquids.
• Lead Wire Length (M): 1, 2, 4, or 8 m
2. The sleeve resists temperatures ranging between −20°C and 70°C
for standard models and 0°C and 100°C for heat-resistive models.
