Robust submersible pressure sensors
WIKA
has extended its portfolio by two high-performance
s
ubmersible pressure sensors with a slimline design. Asa
result of the many options in a single instrument, they offer an exceptionally attractive price-performance ratio. The model LW-1 is suitable for level monitoring of watera
nd wastewater. The model LF-1 features long-lasting resistance withina
ll common oils and fuels. Both submersible pressures
ensors are, with their slimline case diameter of 22 mm(
< 1 inch), ideal for use within pipes. Thanks to a newly developed sealing concept, specialc
able and further options, such as Ex and overvoltage protection during lightning strikes, the instruments work reliably even under harsh conditions.The new submers- ible pressure sensors are available with a variety of output signals.The low-power signals enable battery operation from 3,6 V, and its life is increased enormously through the fast response times and a low current consumption. The monitoring of the medium temperature is possible via an optional analogue output.The parameterisation of unit and error signal, and also the scaling of themeasuring range, is carried out via HART communication.

VEGA
launched theVEGAPULS 64 in 2016, and a new standard was
set for radar sensors.This was the first radar sensor that operated
at a frequency of 80 GHz, producing a beam angle of just 3°. The
focused beam angle allows the sensor to be used in vessels with
internal installations or heavy build up on the walls, producing
accurate measurements even with foam, condensation or tur-
bulent product surfaces. With the new entrant to the market, the
VEGAPULSWL S 61 has reached what John Groom (VEGA Group
Director for Africa), refers to as the ‘holy grail’ of achievement in
the development of radar technology. Designed specifically for
the water supply and sewerage sectors, this radar sensor comes
with an equivalent price tag to the ultrasonic sensors, but with so
many more added advantages.TheWL S 61 comes standard with
built-in Bluetooth capability, a submersion-proof housing and an
encapsulated antenna system. Mounting options include a wall
holder and a ceiling reflector for awkward angles. The integrated
Bluetooth module enables wireless communication with a smart
phone, tablet or PC, making commissioning of the instrument and
diagnosis of operating parameters simpler and safer. As an aside,
VEGA guarantees that Bluetooth can be retrofitted to any of their
sensors sold since 1999.
