    Keller LEO3 Digital Manometer (700bar)

    The Keller LEO3 Digital Manometer has an absolute pressure measurement range of 0 to 700bar with accuracy of ±0.2% FS and a resolution of 200mbar. It works as both a digital pressure gauge, showing readings on screen, and a pressure transmitter, producing an analogue electrical signal, with measurements taken through the G ¼” male connector.

    Pressure readings are shown in a number of units on the Keller LEO3’s digital screen. When min/max is used, the minimum or maximum value recorded is shown alongside the current pressure reading. This can be reset to renew the process. A zero function allows the user to take relative measurements, thereby cancelling out the effects of barometric pressure.

    In addition to the digital display, the Keller LEO3 also produces a 4…20mA analogue current signal from its 723 Binder / RS485 connection. This allows it to connect to an external system and the signal can be reset to 4mA or 20mA to allow relative measurement. The analogue signal value is shown alongside the pressure reading on screen.

    In order to connect to USB ports in a monitoring system, the Keller LEO3 should be purchased with an optional Keller K114B RS485 / USB adaptor cable. When Keller ControlCenterSeries30 software is purchased, the manometer can be connected as part of a Keller Bus protocol with up to 128 other instruments. An IP65 ingress protection rating makes it suitable for challenging conditions.
