Advanced Applications as a Cryogenic Level Sensor

When measuring non conductive liquids at extreme temperatures, standard float switches can fail. The DCS IS operates flawlessly as a dedicated cryogenic level sensor, with the low temperature version capable of withstanding environments down to 200 degrees Celsius below zero. This makes it the ideal safety and measurement solution for liquid nitrogen, argon, and other specialist cryogenic fluids used in the scientific and medical sectors. Because it utilises microprocessor based pulse counting technology, this cryogenic level sensor provides continuous, high resolution feedback without moving parts that could freeze or degrade.

Dimensions

The DCS-IS can be ordered with any length of sensor stem up to 5975mm (19’ 7¼”). The stem length is the active measuring length of the sensor and should not be confused with the stem depth. The stem depth is 60mm longer and includes the non-active section above the measuring length. The stem depth (measuring +60mm) is the length from the shoulder of the mounting thread to the end of the stem probe (Non-standard mounting may have a different length of non-active section).

Operation

The DCS-IS is suitable for measuring non viscus liquids with a dielectric constant (also known as relative permittivity) shown in the tabulated data above. Viscous liquids may produce a delayed level reading, block the sensor stem and eventually dislodge the internal stem spacers.

The sensor stem is constructed from a stainless steel 316 tube around a stainless steel 316 solid rod. The rod is held centrally inside the tube using a PTFE spacer with cut outs to allow the liquid to flow inside the tube. A breather hole at the top of the stem equalises the air pressure.
