Rugged Level Switch excels in high pressures
 
Gems Sensors has announced availability of its most rugged
electro-optic level switch, the ELS-1200CR.

The level switch provides broad chemical compatibility and accurately
monitors liquids within vessels pressurised to 170 bar.

Wetted materials are comprised of glass and Hastelloy C, with a body
made of 316 stainless steel. 

Ideal for outdoor applications, these high pressure units provide
excellent resistance to corrosive environments – both in and out of the tank.
They are suitable for use in most liquids that do not crystallise or leave a
solid residue.

The ELS-1200CR switches feature integrated electronics that eliminate
the need for a separate controller and solid-state design with no moving parts.
These solid-state electronics ensure dependability over a long service life
and are accurate to within +/- 1mm. Operating temperatures range from
–40°C to +100°C.
 
Input power requirements are 5 VDC or 12 VDC, whilst current consumption
is approximately 45mA. Output is TTL or separate solid state relay.

 The ELS-1200CR mounts in a horizontal position (or up to 45 degrees
from horizontal), and easily installs through ¾ inch NPT holes.
The switch body is conveniently formed as a 29mm hex.

The electro-optical switches are designed for OEM use in refrigeration
systems, compressor oil and hydraulic fluid systems, pump, machine
tool and on and off highway vehicle applications.
