New from Keller
is the LEO 3, an additional model to the Mano 2000 series of
digital pressure gauges which is a micro-processor controlled,
accurate and versatile transmitter with a digital pressure indictator
and 4...20mA current output.
The LEO 3 is
available in four ranges, -1...3 bar, -1...30 bar, 0...300 bar
and 0...700 bar, offering a typical accuracy of 0.2%. The display
automatically turns on when the 4...20mA (2 wire, 12...28 V DC
supply) circuit is excited, the top display indicating the actual
pressure and the bottom display showing the actual current of
the 4...20mA output.
A max. or min
feature is also included on the lower display. It can be programmed
using the keys for zero and full scale of the analogue output,
together with unit selection in bar, psi, mbar/hPa, kPa and MPa.
With the Keller
PROG 30 software, the K106 converter and a PC, the zero and full
scale selection of the 4...20mA output and the unit can be programmed
via the RS 485 without applying the pressure to the transmitter.
The LEO 3 is bus compatible and can be provided with an address
and the range changed in operation.
The unit is protected
to IP65 and is fitted with a G 1/4" pressure connection.
It measures 76(diam) x 118(high) x 42(deep)mm, weighs just 230
grams and will operate over as temperature range of 0...50ºC.
