Keller LEO3 Digital Manometer (1000bar)
The Keller LEO3 Digital Manometer works as a pressure transmitter and an industrial digital pressure gauge. It has an absolute pressure measurement range of 0 to 1000bar, accuracy of ±0.1% FS, and a resolution of 200mbar. Pressure measurements are taken via the G 1/4” male connector.
Readings are shown in different units of pressure (bar, mbar/hPa, kPa, MPa, PSI, kp/cm2) on the Keller LEO3’s clear digital display. There is a min/max recording feature that shows the highest or lowest value recorded alongside the current pressure reading whilst a zero function facilitates relative measurements.
The Keller LEO3 can produce an analogue current signal from 4mA to 20mA that allows it function as part of a wider monitoring system. It has a Binder 723 / RS485 connection to transmit the signal and the output can be set to 4mA or 20mA for relative measurement. The output value is shown on screen alongside the digital readout.
To connect the Keller LEO3 to a USB port, an optional Keller K114B adaptor cable is required. It can be coordinated along with up to 127 other instruments in a Keller-Bus protocol via Keller ControlCenterSeries30. The IP65 rating certifies that it is compatible with challenging environments.
