System Sensor ST-5 Sampling Tube while maintaining a mechanical power

while maintaining a mechanical power transmission rating of 78 in-lbs of torque

this sensor is commonly used in units branded under Heil

Key Benefits Forged Brass Construction: High-tensile C360/C370 brass provides maximum wall strength and prevents thermal fatigue or cracking

When the temperature exceeds the 150°F threshold

It provides the added benefit of breaking both legs of the power supply for increased safety during servicing
