New pneumatic level sensors

The new NLS pneumatic level sensors feature a minimum number of moving parts.

They are designed for operational reliability and long life (more than 50,000 switch operations). They install quickly and easily with a standard 12 in. pipe and G1 connection at the top of the tank.

The NLS is engineered for use in high viscosity liquids and is suited for use in process uses where electrical power is not available or hazardous locations exist. It may be used in conjunction with one of this firm’s intrinsic safety barriers to meet hazardous location requirements for level control devices.

UV curable compound laminates and seals

Newly developed UV19, a low viscosity, flexible UV curable composition, is formulated for fast, high performance laminating, sealing, bonding, and casting.

It is an optically clear, mobile liquid that cures readily upon exposure to UV light at ambient temperatures to a flexible, strong solid with what the company says are superior mechanical strength properties and excellent adhesion to substrates including most plastics and glasses as well as metals.

The UV19 system is 100% reactive and does not contain any volatiles. Its cure is not inhibited by air and it exhibits minimal shrinkage when cured. UV19 has excellent resistance to water and many other aggressive chemicals, the company notes.

Low viscosity of less than 300 cps at 75° F. helps enhance its utility for laminating as well as sealing, bonding, and coating applications. Its flexibility (more than 100% elongation) and adhesive properties help suit it for laminating, sealing, and bonding to substrates with widely different thermal expansion coefficients such as, for example, glass and polycarbonate. UV19 has a tensile strength in excess of 800 psi.
