    Keller LEO3 Digital Manometer (300bar)

    With an absolute pressure range of 0 to 300bar, the Keller LEO3 Digital Manometer is a useful pressure gauge and pressure transmitter that has uses across a number of different industries. Readings are accurate to ±0.1% FS and precise to 100mbar. The G1/4” male connector is used to measure pressure.

    As a pressure gauge, the Keller LEO3 shows pressure readings on its digital screen in a number of different units (bar, mbar/hPa, kPa, MPa, PSI, kp/cm2). It has a minimum and maximum recording feature and the zero function enables relative measurements.

    The Keller LEO3 produces an analogue signal alongside its on-screen digital readouts. This 4mA to 20mA signal can be accessed via the 723 Binder connection on the back of the manometer and allows it to be used as part of a wider monitoring system. The signal can be reset to 4mA or 20mA to allow relative measurement and it is displayed on screen with the pressure reading.

    In order to best use the analogue signal from the Keller LEO3, a Keller K114B adaptor cable is required to link up to a USB port. With Keller ControlCenterSeries30 software, up to 128 separate devices can be used to monitor a system as part of a Keller-Bus protocol. The manometer is rated as IP65 and runs from the current loop.
