Product Details

Keller LEO3 Digital Manometer

The Keller LEO3 Digital Manometer is an industrial pressure gauge that combines accurate pressure measurement with a digital display and analogue output. It is capable of measuring both relative (-1 to 3bar) and absolute (0 to 4bar) pressure with an accuracy of ±0.1% FS and a resolution of 1mbar, making it suitable for applications where high precision is needed. Measurements are taken via the G1/4” pressure connector.

As both a transmitter and a digital pressure gauge, the Keller LEO3 produces pressure measurements on screen and a 4…20mA analogue current signal from a Binder 723 connection.

Digital readings can be displayed in a range of units with minimum and maximum recording available as well as a zero function that enables relative measurement. Similarly, the analogue output can be adjusted to 4mA or 20mA to allow for relative measurement.

The current loop value is displayed below the digital reading on screen in normal mode whilst the minimum or maximum reading is displayed alongside the current pressure reading in min/max mode.

The analogue output allows the Keller LEO3 to connect to a computer system when a K114B RS485 to USB Binder connector with software is purchased alongside the manometer. Keller ControlCenterSeries30 software is available from the Keller website. The Keller LEO3 runs from the current loop and its IP65 ingress protection rating certifies that it is suitable for use in the field.
