NLS pneumatic level sensors feature a minimum number of moving parts and are designed for operational reliability and long life (more than 50,000 switch operations). They install quickly and easily with a standard 1/2 in. pipe and G1 connection at the top of the tank. The NLS is engineered for use in high viscosity liquids and is ideal for use in process industry applications where electrical power is not available or hazardous locations exist. It may be used in conjunction with an STI intrinsic safety barrier to meet hazardous location requirements for level control devices.
