XM/XT-860 Series – Compact, Resistive Easy online ordering too! Output Level Sensors
High Volume/Low Cost OEM Design
Brass or Stainless Steel Construction
1/2˝ or 1˝ Resolution
Lengths to 24 inches (610 mm)
OEMs with fluid gauging requirements now have an affordable, yet robust continuous output sensor they can use to great value. Gems XM-860 liquid level sensors are a durable, low-cost solution for applications that don’t require high-resolution output. Made of brass or stainless steel, this series offers rugged construction, utilizing a
new, coated reed switch core that stands up to high levels of shock and vibration. They are equally at home in applications ranging from tranquil storage day tanks to the challenge of off-highway vehicle fluids tank gauging. Minimum order for this series is 250 units.
Gems XM-860 Advantages
• Floats provide true reading of liquid’s surface position
• Floats can be used to sense dissimilar liquid interfaces (e.g. water/oil interface), including resulting emulsions.
• Unaffected by dielectric property of fluid
• Intrinsically-safe and Explosion-proof models available
• Unaffected by turbulence and motion
Typical Applications
