SPIROL specializes in the manufacture of precision machined AAR Nuts for the railroad industry. SPIROL's Railroad Nuts are held 100% square to the tap. SPIROL's thread pitch diameter allowances are engineered for ease of assembly after plating, yet manufactured to strict standards with specific gages. Each production lot has a unique identification number and is traceable through each manufacturing process back to the original raw material test certificate. SPIROL's Railroad Nuts, otherwise referred to as AAR Clamp Nuts, Binding Nuts, and Gold Test Nuts or AAR Signal Nuts are used in signal lights, crossing bells and terminal blocks.

BEDIA level monitoring sensors are used to monitor the filling levels of liquids. The sensors detect when a filling level is exceeded or falls below a limit. Water-based liquids like coolants, AdBlue®, fresh water, waste water and oil-based liquids like motor oils, hydraulic oils, fuels and brake fluids can be monitored. Operating Principle The function of the sensor is based on the capacitive principle. It detects the change in capacitance that occurs when an electrode surrounded by air is immersed into a liquid medium. This change in capacitance at the electrode of the sensor excites an oscillator. This signal is processed by a microcontroller-based evaluation circuit which activates or deactivates an output stage. Types of Media The level monitoring sensors are designed for two different media types: For electrically conductive liquid media with relative permittivity within a range of εr 35 … 85 (water, coolant, water/glycol mixture) For electrically non-conductive liquid media
