Knowing the relative saturation and the exact endpoint criterion for any oil processing or filtering application can save many man-hours
The Domino range of moisture-in-oil sensors available from Vector
Instruments can now be configured to cover an extended range of
Originally designed to monitor the water content of
transformer insulating oils, algorithms have now been developed
which enable the equipment to be used with a much wider range of
mineral, vegetable and silicone oils including proprietary
branded oil products from several suppliers.
There is also the
potential for applications with other liquids which have varying
solubility characteristics for water.
Knowing the relative
saturation (RS) and the exact endpoint criterion for any oil
processing or filtering application can save many man-hours,
materials and chemicals together with hazardous-waste disposal
and analysis costs.
This is particularly applicable to utilities
involved with power generation and distribution, but also has
growing use for both lubrication and hydraulic oils together with
general processing and laboratory testing applications in many
The Domino product is an accurate, simple, robust and
versatile instrument which provides instantaneous and continuous
measurement of water content.
This eliminates the potential time
delays and system errors that can be associated with Karl Fisher
Measurements provided as display information
include water content as relative saturation in %, concentration
in parts per million mg/kg (ppm), and temperature.
the relative saturation (0 to 100%) and temperature can be
displayed, indicating the actual water content in relation to the
media solubility level at a given temperature.
accuracy is claimed to be the best in the industry at +/-1%
including non-linearity and repeatability.
comprises a stainless steel probe housing the moisture and
temperature sensors, rated for operating temperatures up to 180C
and pressures from vacuum to 290psi.
The probe is connected by
cable to a compact transmitter and display unit within a Nema 4
(IP65) housing, suitable for external mounting into any valve
that is 1/2" NPT or larger.
Power supply can be 24Vdc or
115/230Vac, with two analogue outputs default set to 4 to 20mA.
An RS232c connection is also provided to facilitate changing
algorithms for different fluid applications and requirements.
Domino equipment can be supplied suitable for permanent or
temporary mounting, complete with various length cable
A portable sampler version also available is ideal
for use by field service personnel.
