The Leo 3 is a digital pressure indicator designed for permanent installation. It is a combination 2 wire 4-20 mA transmitter with programmable dual local indication of pressure in selectable units: (bar, mbar/hPa, kPa, MPa, PSI and kp/cm2).
This is part of Instrotech's successful Leo range of digital pressure indicators manufactured by Keller of Switzerland and is available for vacuum or pressure measurement.
Standard ranges are 0 to 400 kPa (4 bar) absolute, 0 to 3 Mpa (30 bar) absolute, 0 to 30 MPa (0-300) and 0-70 Mpa (0-700 bar) with a measuring rate of up to 90 times/sec. The units work off supply voltages of 8 to 28 V d.c. with temperature compensation over the range 0-50°C.
The output display is in mA. Besides 4 to 20 mA analog current loop, the transmitter also has an RS485 interface to output the pressure value and access instrument characteristics. The analog output can be programmed without applying pressure to the instrument. The min/max and zero adjustments are performed using the two pushbuttons on the front of the instrument.
The pressure connection is standard G quarter inch parallel thread with a seal and the electrical connection is via a Binder back entry plug. Manufactured to ISO 9001 standards, the Keller Leo 3 offers IP65 environmental protection against dust and low-pressure water jets. Dimensions are 76 x 125 x 50 mm, with a weight of 210 grams.
