Instruments and Instrumentation
MANY years ago, Klay Instruments developed a hydrostatic pressure level transmitter in response to industry demand.
At the time, there was nothing on the market that allowed the levelling device to be removed from the process, cleaned and calibrated without emptying the tank and shutting down the entire process.
Klay Instruments developed a unique combination of a ball valve and a special transmitter in that the extended diaphragm was completely ‘flush’ with the inside tank-wall.
A unique double O-ring construction made the whole design retractable and fully water-tight up to 10 bars – the valve assembly can handle up to 70 bars.
This provided an excellent solution to reliable level and pressure measurement in the dirty fluid-slurries seen in the mining industry.
Nowadays, these valve transmitters are used in the mining, pulp and paper starch, waste water and shipping industries and many more.
Klay Instruments make three different valve transmitters with a stainless steel diaphragm: series 8000 valve with basic accuracy of 0.2pc, series 2000 valve with accuracy of 0.1pc and Hart 5, and series 4000 valve with accuracy of 0.075pc and Hart 7 or Profibus PA.
These series can be supplied with the IECEx approval (Exi T4 up to T6).
There are flanged transmitters (DIN, ANSI or JIS) for level applications and threaded versions (1-inch BSP or 1.5-inch’ BSP) for pressure applications (limited to 10 bars).
The extra thick SS membrane with backing plate and temperature compensate for the minimum amount of fluid to provide excellent accuracy and reliability of the Klay pressure transmitters.
The series 3000 valves are equipped with a capacitive ceramic diaphragm (99.9pc Al2O3) and can be applied in abrasive applications such as wasted paper treatment, mining slurries and mineral slurries.
The above series is just one of the special designs that Klay Instruments has developed for certain applications.
There are high temperature transmitters (up to 350C), high pressure transmitters (up to 1000 bar), and special alloys like Hasteloy C, tantalum, titanium or even gold plate.
And there is also a full range of submersible level transmitters and level switches.
